完整报错:
====================[ Build | AsyncLogger | Debug ]============================= /snap/clion/169/bin/cmake/linux/bin/cmake --build /home/dyy/CLionProjects/AsyncLogger/cmake-build-debug --target AsyncLogger -- -j 6 [ 50%] linking CXX executable AsyncLogger /usr/bin/ld: CMakeFiles/AsyncLogger.dir/main.cpp.o: in function `std::thread::thread(void (&)())': /usr/include/c++/9/thread:126: undefined reference to `pthread_create' collect2: error: ld returned 1 exit status make[3]: *** [CMakeFiles/AsyncLogger.dir/build.make:93:AsyncLogger] 错误 1 make[2]: *** [CMakeFiles/Makefile2:83:CMakeFiles/AsyncLogger.dir/all] 错误 2 make[1]: *** [CMakeFiles/Makefile2:90:CMakeFiles/AsyncLogger.dir/rule] 错误 2 make: *** [Makefile:124:AsyncLogger] 错误 2
解决方法:
在CMakeLists.txt的最后加上:
find_package(Threads REQUIRED) target_link_libraries(AsyncLogger Threads::Threads) #这里AsyncLogger 是你的项目名称
然后reload CMakeLists.txt,编译成功。
原因:
编译器没有链接线程库
