我在fedora 18 64位上。

find_package(Threads REQUIRED)
target_link_libraries(app_suite_tests ${CMAKE_THREAD_LIBS_INIT})

是创建此代码的代码。我该怎么做才能防止CMake在这里抛出错误，或者我如何让CMake通过可执行文件检查pthreads库？

感谢。

Additonal Info：

if(NOT CMAKE_HAVE_THREADS_LIBRARY)
    # Do we have -lpthreads
    CHECK_LIBRARY_EXISTS(pthreads pthread_create "" CMAKE_HAVE_PTHREADS_CREATE)
    if(CMAKE_HAVE_PTHREADS_CREATE)
      set(CMAKE_THREAD_LIBS_INIT "-lpthreads")
      set(CMAKE_HAVE_THREADS_LIBRARY 1)
      set(Threads_FOUND TRUE)
    endif()

来自FindThreads.cmake，并在CHECK_LIBRARY_EXISTS

上抛出错误

Answer 1

此错误特定于cmake 2.8.11+以及具有名为“pthreads”的可执行目标的项目。这是cmake绊倒的可执行文件。重命名可执行文件可解决此问题。另请参阅the Dr. Memory issue tracker entry on this。

Answer 2

我认为你在寻找

ADD_EXECUTABLE(your_executable ${source_files})

TARGET_LINK_LIBRARIES(
pthread
)

取自cmake and libpthread

CMake错误try_compile类型为可执行文件的pthreads
