我在fedora 18 64位。

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

是创建它的代码。我该怎么做才能防止 CMake 在此处引发错误，或者如何让 CMake 通过可执行文件检查 pthreads 库？

谢谢。

附加信息：

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，错误在 CHECK_LIBRARY_EXISTS 上抛出

此错误特定于 cmake 2.8.11+ 和具有名为“pthreads”的可执行目标的项目。那是 cmake 绊倒的可执行文件。重命名可执行文件可解决此问题。另请参阅有关此的 Dr. Memory 问题跟踪器条目。

我想你正在寻找

ADD_EXECUTABLE(your_executable ${source_files})

TARGET_LINK_LIBRARIES(
pthread
)

取自cmake 和 libpthread
