I have a project which creates a shared library and a utility which uses this shared library. I would like to be able to run the utility within the build tree and also from the final install directory. I can do this, it works, but the path hard-coded path in the executable is always the build tree path.
The default RPATH policy works for this: http://www.cmake.org/Wiki/CMake_RPATH_handling#Default_RPATH_settings Unfortunately the build directory path gets "baked in" to the executable, even at install time. If I run "make clean", the executable still seems to find the library even though the copy in the build tree is deleted. However, running "otool -L" (same as "ldd" on Linux) on the executable reveals that the RPATH is still in the build tree rather then the install path: $ otool -L lsusb lsusb: /Users/cwolf/src/cmaketest/libusb-1.0.8/libusb/build/libusb-1.0.dylib (compatibility version 0.0.0, current version 1.0.8) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.0.0) This setting shows which libraries are actually loading at runtime: $ export DYLD_PRINT_LIBRARIES=true clozaril-2:bin cwolf$ ./lsusb dyld: loaded: /private/tmp/local/bin/./lsusb dyld: loaded: /tmp/local/lib/libusb-1.0.dylib dyld: loaded: /usr/lib/libgcc_s.1.dylib dyld: loaded: /usr/lib/libSystem.B.dylib dyld: loaded: /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation dyld: loaded: /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit [...] As can be seen, the executable is dynamically linking with the install directory (/tmp/local/lib) The preceding is observed regardless of whether I use the default RPATH settings or if I use "Always Full RPATH": http://www.cmake.org/Wiki/CMake_RPATH_handling#Always_full_RPATH ...which supposedly relinks the executable upon "make install" such that the RPATH is changed to the install path - but I don't see that. Any ideas? _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
