c – CMake链接错误pthread：启用多线程以使用std :: thread：不允许操作

我有一个像以前一样的错误
C++ Threads,std::system_error – operation not permitted?

我正在使用完全相同的源代码并进行编译

g++ ../src/main.cpp -pthread -std=c++11

工作没有任何问题.

因为我想在更大的项目中使用线程,所以我必须使用CMake的线程.在搜索解决方案后,我发现了几个代码,例如：

cmake_minimum_required (VERSION 2.6)
project (Test)
add_deFinitions("-std=c++11")

find_package (Threads)
add_executable (main src/main.cpp)
target_link_libraries (main ${CMAKE_THREAD_LIBS_INIT})

但对我而言,我总是这样做不起作用：

terminate called after throwing an instance of 'std::system_error'
  what():  Enable multithreading to use std::thread: Operation not permitted
Aborted (core dumped)

我的错是什么？

CMake输出看起来很有希望：

解决方法

编辑：
我现在正在使用GCC 5.4,有问题的cmake片段工作正常.

我刚刚面临同样的问题.我这样的最终cmakelist.txt文件,它的工作原理.

cmake_minimum_required (VERSION 2.6)
project (Test)
SET(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} "-std=c++11 -pthread")

find_package (Threads)
add_executable (main src/main.cpp)
target_link_libraries (main ${CMAKE_THREAD_LIBS_INIT})
