Summary | 0011375: CMake searching of library path on AMD64 architectures with GNU/Linux | ||||||||
Description | When searching for libraries in pure CXX projects in Linux on 64 bits systems, the lib64 directories are not searched, even with the FIND_LIBRARY_USE_LIB64_PATHS macro set. Adding the 64 prefix works in pure C or hybrid C/CXX projects. | ||||||||
Additional Information | The file hierarchy standard (http://www.pathname.com/fhs/pub/fhs-2.3.html#LIB64 [^]) specifies that the "lib" directories will house 32bits binaries on PPC64, s390x, sparc64 and AMD64 architectures running GNU/Linux. While the FIND_LIBRARY_USE_LIB64_PATHS property allows to mitigate this problem, it still has a few quircks : * Even setting the property at global level do not seem to apply to subsequent find_package calls * If a 32bit library with the adequate name is found in "lib" directories, it will be used instead of the native version | ||||||||

Hmm, it seems that my test was a bit hasty: The problem was observed with a pure C++ project (using the macro PROJECT(myproject CXX) at the begining of the CMakeLists.txt). Tracking the issue, i went into the cmFindLibraryCommand.cxx file and saw at begining of the cmFindLibraryCommand::AddLib64Paths() function that searching for lib64 variants is only enabled when project is C-enabled. Transforming it in a C/CXX enabled project is a workaround. I tried enlarging the conditional to allow CXX projects, but it was a mitigated success since some findpackages calls requires a C compiler to build their internal test programs. Maybe this bug should be closed and reopened with a proper description of the problem? |

You don't need to close and re-open the bug. As the reporter of a still open bug, you should be able to edit the summary and description fields to reflect reality. Would you mind re-phrasing this issue to tell us exactly what the problem is and what you think should be done to fix it? Thanks. |

I'm sorry, I can't find where to edit the description of the bug report. A correct rephrasement of the issue should be : "When searching for libraries in pure CXX projects in Linux on 64 bits systems, the lib64 directories are not searched, even with the FIND_LIBRARY_USE_LIB64_PATHS macro set. Adding the 64 prefix works in pure C or hybrid C/CXX projects." |
