OpenMP库规范 [英] OpenMP library specification

问题描述

我是新来打开mp的人，并且尝试了来自官方网站的示例程序

i am new to open mp and i tried an sample program from the official site

#include <omp.h>
#include <stdio.h>
int main() {
#pragma omp parallel
printf("Hello from thread %d, nthreads %d\n", omp_get_thread_num(), omp_get_num_threads());
}

并且我在Eclipse中将库设置为项目Properties-> GCC c ++ linker-

and i have set the library in the eclipse as libgomp in project Properties->GCC c++ linker-

但是程序说/usr/bin/ld: cannot find -llibgomp我可以知道我哪里错了

but the program say /usr/bin/ld: cannot find -llibgomp can i know where i am wrong

推荐答案

尝试使用gomp而不是libgomp进行链接:库名称必须不带lib前缀而自动传递给链接器.因此，该错误正在尝试找到liblibgomp.不要忘记编译器标志-fopenmp，否则OpenMP编译指示将被忽略.

Try linking with gomp instead of libgomp: library names must be passed to the linker without the lib prefix, which it adds automatically. Hence the error, it is trying to find liblibgomp. Don't forget the compiler flag -fopenmp, otherwise the OpenMP pragmas will simply be ignored.
