并行程序给出错误"对_Kmpc_ok_to_fork的未定义引用"

Question

我想在linux上编译OPENMP fortran代码.我有大约230个子程序.我用来编译代码的代码如下:1)首先,我使用以下命令编译每个子例程

ifort -c -override-limits -openmp *.for

然后所有子程序现在都有一个单独的目标文件.

2)然后我尝试通过以下命令将目标文件编译为可执行文件

ifort *.o -o myprogram

我收到以下错误:

我正在使用intel 13 composer来编译程序.我不知道如何使用与libiomp5md的链接.

请帮我摆脱这个错误.我试了好几次但是我没有得到这个错误.

如果我不使用openmp标志程序运行但它不会被视为openmp程序.

谢谢

对英特尔论坛的快速扫描表明,您可能还需要-openmp第二个命令上的选项,以使其链接到OpenMP库.

你可以通过谷歌搜索自己找到这个 __kmpc_global_thread_num
