Question

There was once a bug related to cmake and pthread but it is now fixed

我在Mac OS上使用cmake版本3.5.1。它先前已编译，但与此同时我安装，更改或更新了一些东西。我对cmake知之甚少。 cmake文件是由其他人编写的。

这是我收到的错误消息：

-- Looking for pthread.h
-- Looking for pthread.h - not found
CMake Error at /usr/local/Cellar/cmake/3.5.1/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message):

我该如何解决这个问题？

Answer 1

感谢@Tsyvarev。问题是“-fopenmp”标志导致错误，因为编译器设置为clang。

来自CMakeFiles / CMakeError.log

clang: error: unsupported option '-fopenmp'

将C ++编译器更改为g ++并从c编译器中删除该标志解决了这个问题。

Cmake失败了pthread.h
