Loïc Bartoletti <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #5 from Loïc Bartoletti <[email protected]> --- I think it's a false positive. cmake use FindThreads module to determine how to build thread program. First it searches pthread.h https://gitlab.kitware.com/cmake/cmake/-/blob/d6da6784bfdb59456942d11d476593906945adbb/Modules/FindThreads.cmake#L144 > -- Looking for pthread.h > -- Looking for pthread.h - found We have pthread.h, so how to link it? With -lpthread, -lpthread, -lthread or libc? This part, and this is the test in the CMakeError.log file, is not for us. CMake will > Check if pthread functions are in normal C library. > We list some pthread functions in PTHREAD_C_CXX_TEST_SOURCE test code. > If the pthread functions already exist in C library, we could just use > them instead of linking to the additional pthread library. From https://gitlab.kitware.com/cmake/cmake/-/blob/d6da6784bfdb59456942d11d476593906945adbb/Modules/FindThreads.cmake#L158-166 > -- Performing Test CMAKE_HAVE_LIBC_PTHREAD > -- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed So, CMake will check with pthread, https://gitlab.kitware.com/cmake/cmake/-/blob/d6da6784bfdb59456942d11d476593906945adbb/Modules/FindThreads.cmake#L171-177 -- Check if compiler accepts -pthread -- Check if compiler accepts -pthread - yes It found pthread.h and libpthread, we can build the code. -- You are receiving this mail because: You are the assignee for the bug.
