Ubuntu使用多线程cmake时出现undefined reference to `pthread_create' 原因是ubuntu需要查找Threads第三方库,不能直接使用,因此,在cmakelists.txt文件中添加以下两行代码就ok find_package(Threads) target_link_libraries(HELLO${CMAKE_THREAD_LIBS_INIT})
缺少:libittnotify.a undefined reference to `__itt_region_end_ptr__3_0' 五、解决方法 先完整编译opencv 环境 https://www.jianshu.com/p/f73fcb9a0b1a 再使用 locate 查找 .a静态文件
