Cmake Rpath

After inspecting with otool the problem was the @rpath or LC_RPATH which not set on the Dolphin executable (target dolphin-emu ) which needed by libqcocoa. Not using ELF, no RPATH support. It controls runtime linkage only, not actual linker behaviour - talonmies 5 mins ago. Setting CMAKE_SKIP_RPATH for this version would avoid RPATHs in build-dir too. When the software is installed the executables etc are relinked by CMake to have the install RPATH. INSTALL_NAME_DIR="") works for every case. #At file:///Users/jimw/my/libmysql-1. The ``@rpath`` in an install name is a more flexible and powerful mechanism than ``@executable_path`` or ``@loader_path`` for locating shared libraries. This CMake version should handle RPATHs issues correctly (set them in build-dir, remove them during installation). CMAKE_SKIP_RPATH:BOOL=NO //Flags used by the linker during the creation of static libraries // during all build types. Cross Compiling for Raspberry Pi – Part II February 4, 2016 · by solderspot · in how things work , raspberrypi , software · 17 Comments In a previous post I described how to use a Ubuntu instance to compile a simple “hello world” program that runs on the Raspberry Pi.

The release containing this fix may be available for download as an Early Access Release or a General Availability Release. Other platforms don't have this problem either by not having them (Windows) or library lookups being purely filename based (Linux and other ELF platforms) rather than supporting directory traversal like macOS does. mkdir build cd build/ cmake. If this variable is set to true then the software is always built with the install path for the RPATH and does not need. CMAKE_SKIP_RPATH-ADVANCED: INTERNAL =1 //ADVANCED property for variable: CMAKE_STATIC_LINKER_FLAGS. Use the cmake_policy command to. CMake为了方便用户的安装,默认在make install之后会自动remove删除掉相关的RPATH,这个时候你再去查看exe的RPATH,已经发现没有这个字段了。 因此,当每次make install之后,我们进入到安装路径下执行相关exe的时候,就会发现此时的exe已经找不到相关的库路径了,因为. Manage RPATHs¶. [Openrti-devel] CMake relinking produces broken rpath for libOpenRTI-NG. CMAKE_INSTALL_RPATH_USE_LINK_PATH: Add paths to linker search and installed rpath. Note: if you don't want to modify the cmake scripts themselves, setting property around, you can launch you cmake with a directive asking to not remove the runtime path: See "Variables that Control the Build", with variable: "CMAKE_SKIP_RPATH" If true, do not add run time path information. cmake is loaded. 2 available for download Robert Maynard via CMake [CMake] Suppress a specific path in the RPATH of an executable explicitly Cornelis Bockemühl. 8) project (app. Path /usr/lib/rpm/cmake3. GitHub Gist: instantly share code, notes, and snippets. By default, cmake creates binaries with their RPATH pointing to the appropriate places in the build tree, so they can be run without being installed. Normally CMake uses the build tree for the RPATH when building executables etc on systems that use RPATH. The CMake program provides a great deal of control over how you configure a MySQL source distribution. CMAKE_SKIP_INSTALL_RPATH:BOOL=NO //If set, runtime paths are not added when using shared libraries. When the RPATH was removed, you need to add pyscf/lib and pyscf/lib/deps/lib in LD_LIBRARY_PATH. In addition to improvements in the CMake build system, a new tool called CPack has been added to the CMake family. The -rpath option is also used when locating shared objects which are needed by shared objects explicitly included in the link; see the description of the -rpath-link option. 8) project (app. CMake has introduced CMP0042 in CMake 3. try using -rpath or -rpath-link: knobby67: Programming: 5: 11-12-2015 02:04 PM: cmake: Using find_package(Boost) when FindBoost.

Use the cmake_policy command to set the policy and suppress this warning. The JasPer Project is an open-source initiative to provide a free software-based reference implementation of the JPEG-2000 codec. If this is set to TRUE, then the rpath information is not added to compiled executables. c -L/usr/local/lib -lfoo means that either. 15: CLI upgrade. HAVE_QHULL. Dynamic linking loaders use the rpath to find required libraries. dylib contains absolute (build) path On MacOS library need to find itself and by default they use an absolute path. In Addition to the pkg-config support discussed on the previous pages, HPX comes with full CMake support. I'd like to use CMake, GTest, and TBB for a project on linux, and so far I've been able to build without complaint, but the dynamic linking required by TBB has been a bit of an issue for only one of the libraries. Did you try to play with that? i. If you edit this file, the new values will be used next time you run cmake. Description of problem: Please drop -DCMAKE_SKIP_RPATH:BOOL=ON from %cmake rpm macro. So the rpaths values are:. The current state of affairs is well summarized on the Debian wiki, which lists the library search path: the RPATH binary header (set at build-time) of the library causing the lookup (if any) the RPATH binary header (set at build-time) of the executable; the LD_LIBRARY_PATH environment variable (set at run-time). Variables in conanbuildinfo. The subsequent inclusion and possible path manipulation (by the user) in RootInstallDirs. The current state of affairs is well summarized on the Debian wiki, which lists the library search path: the RPATH binary header (set at build-time) of the library causing the lookup (if any) the RPATH binary header (set at build-time) of the executable; the LD_LIBRARY_PATH environment variable (set at run-time). com/en-us/autonomous tson-nano/). Before Anaconda 5. This variable is used to initialize the MACOSX_RPATH property on all targets. CMake does not support “mex” compiler naturally, so you need to insert the following commands in your CMakeLists. Manage RPATHs¶. Building libobjc2 with CMake + Clang + MinGW on Linux. This is used to initialize the target property INSTALL_RPATH for all targets. txt文件,然后用cmake命令将CMakeLists. 在分发程序的时候,执行文件使用的链接库在系统内不一定会有,或者自带了的版本不对,一般都会在程序文件夹内都会附带相应的链接库,所以最好还是把 rpath 加上。cmake对rpath提供了很多选项支持,我们一般只关注这几个变量就好了: cmake_skip_build_rpath 、 cmake_build_with_install_rpath. Description Qt 5 libraries are built with rpath. This allows improved compiler capabilities, including better security and performance. Manage RPATHs¶. Variables in conanbuildinfo. Okay, so I figured that I would need to add -lobjc to the CMAKE_CXX_FLAGS, but it never occured to me to add a linker search path for the library. This might link binaries against system-libraries (e. CMake和RPATH 默认情况下,CMake在编译时将库文件的搜索路径写入目标文件的DT_RPATH字段。但是在执行make install进行安装后,安装文件的DT_RPATH字段却消失了。. so libraries --- those never have the correct rpath setting. set( CMAKE_BUILD_WITH_INSTALL_RPATH ON ) set( CMAKE_INSTALL_NAME_DIR "@rpath" ) # the RPATH to be used when installing: set( CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib" ) # add the automatically determined parts of the RPATH # which point to directories outside the build tree to the install RPATH: set( CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE ). All steps are performed using Linux on the BeagleBone platform, but the instructions are relevant to most Linux platforms. #At file:///Users/jimw/my/libmysql-1. 在分发程序的时候,执行文件使用的链接库在系统内不一定会有,或者自带了的版本不对,一般都会在程序文件夹内都会附带相应的链接库,所以最好还是把 RPATH 加上。. prov /usr/lib/rpm/fileattrs/cmake3.

The problem is that rpath is not transitive. Help: Fixed typo in CMAKE_INSTALL_RPATH_USE_LINK_PATH. I then set INSTALL_RPATH_USE_LINK_PATH and BUILD_WITH_INSTALL_RPATH to TRUE. The cache is used by the run-time linker, ld. 0 project is to perform builds of Python and wxPython for all of our supported platforms. rpath is an instruction to the linker to hard code a runtime library search path into the executable. Even when this is stripped at installation time, the build-id section will be different. I think I might have stumbled into a bug in the libstdc++, but want to check: Currently I have: # use, i. 4 you can now target Linux from your CMake projects. CMake does not support “mex” compiler naturally, so you need to insert the following commands in your CMakeLists. @executable path, @load path and @rpath Edit Created 11/5/2010 , updated 5 weeks ago Note: this article is actually about the @executable_path , @load_path and @rpath install paths used by the linker on Mac OS X ; wiki titles can't include underscores, however, because they are ambiguous with spaces. Setting CMAKE_SKIP_RPATH for this version would avoid RPATHs in build-dir too. CMake is used to control the software compilation process using simple platform and compiler independent configuration files. These options control various sorts of optimizations. I rechecked every shared library, and those using CMake's install method have the same issue. It's used by many popular open source projects including LLVM, Qt, KDE and Blender. If you have many source files which you don’t want to manually set, you can also do. In any case, @rpath/foo/bar/baz. Other platforms don't have this problem either by not having them (Windows) or library lookups being purely filename based (Linux and other ELF platforms) rather than supporting directory traversal like macOS does. so) is to resolve the executable's dependencies on shared libraries and to load the required ones at run-time. The rpath is encoded inside dynamic libraries and executables and helps the linker to find its required shared libraries. Clang and llvm already use llvm_setup_rpath(), so this change will help standarize rpath usage across all projects. By default if you don't change any RPATH related settings, CMake will link the executables and shared libraries with full RPATH to all used libraries in the build tree. dylib in the build tree. cmake-gui does not seem to be built with the correct rpath. set_target_properties(foolib PROPERTIES SKIP_BUILD_RPATH TRUE) Ideally this change would be upstreamed. Run "cmake --help-policy CMP0042" for policy details. I think I might have stumbled into a bug in the libstdc++, but want to check: Currently I have: # use, i. The defaultis to add rpath information if the platform supports it. This page has moved here. to the properties on the relevant binary in CMakeLists. CMake and friendsmore than just a buildsystem Alexander Neundorf advanced RPATH handling. Package declared variables:. Lets look at tevent. If this is set to TRUE, then the rpath information is not added to compiled executables. m4 /usr/share/bash-completion/ /usr.

CMake Install. So let's look at each step in more detail and how to implement it in CMake. We’ll use CMake as build system in this case but keep in mind that Conan works with any build system and is not limited to using CMake. To begin, change directory (cd) to the pscf/cmake/ directory. When the software is installed the executables etc are relinked by CMake to have the install RPATH. Cmake doesn't work with following output:. so or ld-linux. PROJECT_LABEL can be used to change the name of the target in an IDE like visual studio. 0 Context: I'm currently moving google/or-tools from static dependencies to dynamic one, unfortunately protobuf don't use @rpath/ as prefix path contrary to gflags and glog so it is difficult for me to recreate our sdk since libprotobuf. Possible solutions: - manually add rpath to linker flags (similar as we currently do in releng) - use target_link_libraries to add it as library so that cmake automatically does the right thing. codechaser 349 天前 via Android. mkdir build cd build/ cmake. CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will append directories in the linker search path and outside the project to the INSTALL_RPATH. Considering RPATH and LD_LIBRARY_PATH I've been using rpath embedded in an executable to set a high-priority library search path. CMAKE_SKIP_RPATH TRUE) However, any effect was not visible: the "old" path is still included in RUNPATH. fug-graphics. Reviewers None. txt you can leverage the find_package command integrated into CMake. The executable is hardwired with a path (RPATH) that points to where to look for library dependencies. The program compiles and links perfectly, but when i try to run it i get. Here are some examples of how to use the high-level driver:. The CMake community Wiki has moved to the Kitware GitLab Instance. When combined with other build best-practices, not pasting dependencies in your source tree and locally installing your dependencies, the rule has led to some interesting CMake usage. When the target is created the values of the variables CMAKE_INSTALL_RPATH, CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH, CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to initialize these properties. The cache is used by the run-time linker, ld. CMAKE_SKIP_RPATH:BOOL=NO //Flags used by the linker during the creation of static libraries // during all build types. CMAKE_BUILD_RPATH¶ Semicolon-separated list specifying runtime path (RPATH) entries to add to binaries linked in the build tree (for platforms that support it). Use the install path for the RPATH. SET (CMAKE_SKIP_BUILD_RPATH FALSE) # when building, don't use the install RPATH already # (but later on when installing) SET (CMAKE_BUILD_WITH_INSTALL_RPATH FALSE) # add the automatically determined parts of the RPATH # which point to directories outside the build tree to the install RPATH: SET (CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE). If a file missing an RPATH is an executable, the script aborts; if only libraries are are missing an RPATH, the script does not abort. To begin, change directory (cd) to the pscf/cmake/ directory. It can be stored there at link time by the linker. In any case, @rpath/foo/bar/baz. Hi, I have a problem trying to compile a small application that uses QtOpenGL with CMake. The default is to add rpath information if the platform supports it. CMAKE_SKIP_BUILD_RPATH¶ Do not include RPATHs in the build tree. caffe能跨平台么,能否移植到arm嵌入式设备?或者其他的深度学习框架有没有移植到arm嵌入式平台的案例(…. Jump to navigation Jump to search. Introduction. The rpath is encoded inside dynamic libraries and executables and helps the linker to find its required shared libraries. Triplet files Triplet is a standard term used in cross compiling as a way to completely capture the target environment (cpu, os, compiler, runtime, etc) in a single convenient name. a) with some other libs/dll in Ubuntu 18. This post isn't the standard "modern CMake" fair. CMake is a versatile tool that helps you build C/C++ projects on just about any platform you can think of. CMake also manages building and linking multiple languages into executables or shared libraries automatically. CMAKE_SKIP_RPATH-ADVANCED: INTERNAL =1 //ADVANCED property for variable: CMAKE_STATIC_LINKER_FLAGS. Here are the CMake files: @project(tracking-example) cmake_minimum_required(VERSION 2. Other platforms don't have this problem either by not having them (Windows) or library lookups being purely filename based (Linux and other ELF platforms) rather than supporting directory traversal like macOS does. The importance of RPATH/RUNPATH functionality for improved runtime robustness and ease of use will also be explained, along with some associated support CMake provides. So, we have mentioned that with DEPENDS var. names["cmake"] if specified:. automake/cmake supports RPATH build of binaries, see [3] that helps to make binaries find their associated libraries (libfoo. 0 Context: I'm currently moving google/or-tools from static dependencies to dynamic one, unfortunately protobuf don't use @rpath/ as prefix path contrary to gflags and glog so it is difficult for me to recreate our sdk since libprotobuf. This supersedes the existing “-E remove” and “-E remove_directory” tools and has better semantics. CMAKE_SKIP_RPATH:BOOL=NO //Flags used by the linker during the creation of static libraries // during all build types. It's a property which assigns the specific library search paths for the current ELF. Instead of using LD_LIBRARY_PATH which is very brittle, the search path gets put right into the executable, so you can do things like search the same directory where the exe is for the libs it depends on before. This helps achieving relocatable and reproducible builds that are invariant of the build directory. This back end was contributed by Mentor Graphics. This is used to initialize the BUILD_RPATH target property for all targets. 8以上,MACOSX_RPATH会默认启动,这时候编译的执行文件在查找链接库的时候会往@rpath上搜索,所以就找不到要链接的库(libadk. It's used by many popular open source projects including LLVM, Qt, KDE and Blender. 2020-03-22 - Christoph G - update to 3. One way to configure CMake is to use the CMake GUI. Use the cmake_policy command to. set_target_properties(foolib PROPERTIES SKIP_BUILD_RPATH TRUE) Ideally this change would be upstreamed. Normally CMake uses the build tree for the RPATH when building executables etc on systems that use RPATH. This CMake version should handle RPATHs issues correctly (set them in build-dir, remove them during installation). Did you try to play with that? i. Last, it's recommended to set a scratch directory for PySCF. Note that if you're using cmake, it will automatically strip the rpath from all files when running make install, so you may need to disable that by setting CMAKE_SKIP_INSTALL_RPATH to false in your. For convenience, the system install includes CMake config files for easily finding and configuring Eigen in your CMakeLists. PROJECT_LABEL can be used to change the name of the target in an IDE like visual studio. Maybe I overlooked one more imported target, overriding the effect of above, or it does not work on imported targets at all. The release containing this fix may be available for download as an Early Access Release or a General Availability Release. conf, and in the trusted directories (/lib and /usr/lib). 0 and later prefer this property to. When the RPATH was removed, you need to add pyscf/lib and pyscf/lib/deps/lib in LD_LIBRARY_PATH. unittest/Transforms/IPO or unittest/ExecutionEngine/Orc. This property is initialized by the "CMAKE_INSTALL_REMOVE_ENVIRONMENT_RPATH" variable. 2 for Linux; Dynamsoft Barcode Reader 5. cmake is not in the default location: damien_d: Programming: 3: 10-27-2010 03:40 PM: Java Rpath ? maas187: Linux - Software: 2: 09-27-2009 05:20 AM "qmake not found!" -- Qt-4.

I used CMake to compile&link a cuda-based static library (sbd_yolov2_detect. Dynamic linking loaders use the rpath to find required libraries. CMake Warning (dev): Policy CMP0042 is not set: MACOSX_RPATH is enabled by default. Variables in conanbuildinfo. This option is ON by default which complies with the BASIS standard. Note that unless set, all boolean options default to OFF. Setting CMAKE_SKIP_RPATH for this version would avoid RPATHs in build-dir too. Anyway, it would be much easier if I could simply drop one specific path explicitly with some setting!. org), which has chosen CMake as its build system. Clang and llvm already use llvm_setup_rpath(), so this change will help standarize rpath usage across all projects. If we have an executable, my_exe, that requires a shared library, shared_lib_1, and shared_lib_1, in turn, requires another shared_lib_2.

My second question is about Python. dynamic section of the ELF executable or shared libraries, with the type DT_RPATH, called the DT_RPATH attribute. No needs to repeat that in the title. If your code base is cross-platform you can target both Windows and Linux from within Visual Studio. [Openrti-devel] CMake relinking produces broken rpath for libOpenRTI-NG. When building a target with RPATH, CMake determines the RPATH by using the directories of all libraries to which this target links. For reference, there is an ​ upstream discussion on rpath and OS X. @lasote I would have thought so (based on the name) but a quick test reveals that even when setting CMAKE_BUILD_RPATH instead of CMAKE_INSTALL_RPATH, it's still necessary to set CMAKE_BUILD_WITH_INSTALL_RPATH. Rpath, or the run path, is a way of embedding the location of shared libraries in the executable itself, instead of relying on default locations or environment variables. When the software is installed the executables etc are relinked by CMake to have the install RPATH. When the software is installed the executables etc are relinked by CMake to have the install RPATH. a) with some other libs/dll in Ubuntu 18. Is there a way to tell cmake to keep the install rpath in place? My second question is about Python. An RPATH is a directory (or list of directories) that is linked directly into an executable's binary. CMake is a meta build tool that allows you to generate native build scripts for a range of platforms: See the full list of CMake generators.

C/C++ (14) CMake (7) work-planet (12) The run-time search path (rpath) defines paths to search for dynamic libraries when executing a program. 具体可以通过readelf -d. If this variable is set to true then the software is always built with the install path for the RPATH and does not need. You are receiving this mail as a port that you maintain is failing to build on the FreeBSD package build server. Bug 165008: [CMake] build fails after update to cmake 3. In the spec file of my rpm I decided to add some make test. The -rpath option is also used when locating shared objects which are needed by shared objects explicitly included in the link; see the description of the -rpath-link option. This allows for easy running from the build tree. # note: CMake will add an RPATH to this executable which is the absolute location of libfoo. GitHub Gist: instantly share code, notes, and snippets. 最近研究CMake,发现CMake对于RPATH的管理也非常人性化。官方说法是当动态库的编译也和执行档在同级目录下的时候,CMake会自动给执行档加入适当的RPATH.

If it isn't obvious, the first two commands make a build directory, because it's usually advised to keep build files separate from the main files. the job of dynamic linker and loader(ld. This is used to initialize the target property INSTALL_RPATH for all targets. This variable is used to initialize the MACOSX_RPATH property on all targets. An RPATH is a directory (or list of directories) that is linked directly into an executable's binary. m4 /usr/share/bash-completion/ /usr. It can be stored there at link time by the linker. If this variable is set to true then the software is always built with the install path for the RPATH and does not need. 57 #list(FIND CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES "${CMAKE_INSTALL_PREFIX}/lib" isSystemDir). bin to find the NEDDED headers and search the DSO with a matching SONAME. You typically use it when you have a sub-project inside of your project folder. We don't really need @rpath, so we can just disable it at the global scope instead of fixing the script. CMAKE_SKIP_INSTALL_RPATH:BOOL=NO //If set, runtime paths are not added when using shared libraries. Now we have to inherit cmake package using inherit directive. CMake is a versatile tool that helps you build C/C++ projects on just about any platform you can think of.

CMAKE_MACOSX_RPATH. CMake has introduced CMP0042 in CMake 3. The -rpath option is also used when locating shared objects which are needed by shared objects explicitly included in the link; see the description of the -rpath-link option. As the directory structure for the build and installation differ, the variables CMAKE_BUILD_WITH_INSTALL_RPATH and CMAKE_INSTALL_RPATH_USE_LINK_PATH must be set to false. If this variable is set to true then the software is always built with no. make And done. A "BUILD_RPATH" target property and corresponding "CMAKE_BUILD_RPATH" variable were added to support custom "RPATH" locations to be added to binaries in the build tree. 0/ based on revid:[email protected] 2839 Jim Winstead 2009-04-17 Add support for compiling with OpenSSL instead of the bundled YaSSL. This CMake version should handle RPATHs issues correctly (set them in build-dir, remove them during installation). \llvm; ninja clang This will build just clang.

Tulip was originally built using autotools. txt, we set CMAKE_BUILD_WITH_INSTALL_RPATH to ON, and then for the unit tests we set it to /. org), which has chosen CMake as its build system. Clang and llvm already use llvm_setup_rpath(), so this change will help standarize rpath usage across all projects. XXX is the name of the require in uppercase. Run "cmake --help-policy CMP0042" for policy details. Considering RPATH and LD_LIBRARY_PATH I've been using rpath embedded in an executable to set a high-priority library search path. Normally CMake uses the build tree for the RPATH when building executables etc on systems that use RPATH. Manage RPATHs¶. This might link binaries against system-libraries (e. In addition to improvements in the CMake build system, a new tool called CPack has been added to the CMake family. This works for tests that live in unittest/, but not for those that live in subdirectories e.

Set up the installation paths via the [DESTINATION dir. dylib which the packaging script doesn't understand. The rpath, or runpath if it is present, is where the runtime linker should look for the libraries needed for a program. Description of problem: Please drop -DCMAKE_SKIP_RPATH:BOOL=ON from %cmake rpm macro. CMAKE_INSTALL_RPATH_USE_LINK_PATH is an interesting and very useful option. CMAKE_SKIP_RPATH:BOOL=NO //Flags used by the linker during the creation of static libraries // during all build types. Due to the flexibility of this mechanism for finding dependent shared libraries, use of @rpath within install names should be considered over @loader_path or @executable_path. In case of Linux, the dynamic linker usually is GNU ld. Dynamic linking loaders use the rpath to find required libraries. CMAKE_BUILD_RPATH¶ Semicolon-separated list specifying runtime path (RPATH) entries to add to binaries linked in the build tree (for platforms that support it). chrpath changes, lists or removes the rpath or runpath setting in a binary. The next command is CMake in action. The rpath is encoded inside dynamic libraries and executables and helps the linker to find its required shared libraries. 编译目标代码时指定的动态库搜索路径(指的是用-wl,rpath或-R选项而不是-L);. The rpath of an executable or shared library is an optional entry in the. Hi, I am in a situation where I have to use 2 versions of the boost library (c++), one "explicitly" and one indirectly (through a package that comes as a shared lib). Will affect IDEs in the long run. Not using ELF, no RPATH support. WANT_DISTROBUILD : Turn off RPATH (SET(CMAKE_SKIP_RPATH TRUE) and SET(CMAKE_INSTALL_RPATH "")) WANT_NORPATH : Turn off RPATH (SET(CMAKE_SKIP_RPATH TRUE) and SET(CMAKE_INSTALL_RPATH "")) WANT_NO_EXAMPLES (1. install_name_dir是一个字符串属性,它用于在mac osx系统上,指定了被安装的目标中使用的共享库的"install_name"域的目录部分。如果目标已经被创建,变量cmake_install_rpath, cmake_install_rpath_use_link_path, cmake_skip_build_rpath, cmake_build_with_install_rpath和cmake_install_name_dir的值会被. Clang and llvm already use llvm_setup_rpath(), so this change will help standarize rpath usage across all projects. Getting Started¶. The current state of affairs is well summarized on the Debian wiki, which lists the library search path: the RPATH binary header (set at build-time) of the library causing the lookup (if any) the RPATH binary header (set at build-time) of the executable; the LD_LIBRARY_PATH environment variable (set at run-time). Manage RPATHs¶. rpath is an instruction to the linker to hard code a runtime library search path into the executable. General observations: The -rpath linker option accepts a single path which is added as a "LC_RPATH load command" to a Mach-O binary. Using CMake with executables. Set up the installation paths via the [DESTINATION dir. I'm trying to make CMake add to the linker RPATH automatically. 8) project (app. When the target is created the values of the variables CMAKE_INSTALL_RPATH, CMAKE_INSTALL_RPATH_USE_LINK_PATH, CMAKE_SKIP_BUILD_RPATH, CMAKE_BUILD_WITH_INSTALL_RPATH, and CMAKE_INSTALL_NAME_DIR are used to initialize these properties. I am trying with gcc-openmpi and xl-spectrum_mpi but I am encountering identical problems which is that application do not link against hdf5.
