Look at "cmInstallTargetGenerator::AddChrpathPatchRule". Its job is to generate the install-time script to fix up the RPATH in the installed binary. The default is *no* RPATH, unless the INSTALL_RPATH target property is set: http://www.cmake.org/cmake/help/cmake-2-8-docs.html#prop_tgt:INSTALL_RPATH Elsewhere in this thread (at least on the kde list) you mention this seems to be working for some targets and not others. Look for where the INSTALL_RPATH gets set on the targets where it is working. > Found it already, I've patched a cmake checkout here to give some > diagnostic output and looking at the differences its apparent that for > kdevplatform the installation prefix is not added to the > "OrderRuntimeSearchPath" list in cmComputeLinkInformation, but this is > done for kdevelop targets. This has nothing to do with RPATH_REMOVE or RPATH_CHANGE calls during installation. The only time this code would be used with install-tree information is during the "relink" step used on non-ELF platforms used to build a new RPATH into the binaries for installation. > The reason seems to be that when building kdevplatform there are no > libraries in the install-prefix that the to-be-built targets link > against.

No, this is intentional behavior. CMake sets the RPATH up in the build tree to help the binary find its dependencies at runtime. If it does not link to anything in <prefix>/lib then there will be no RPATH entry for it. > That should help in this case (I didn't test this yet) As I said above it won't affect the install tree. See the INSTALL_RPATH target property. -Brad _______________________________________________ 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
