我正在尝试在 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）一开始我用下面的命令编译了每个子程序

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

然后所有的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。我尝试了几次，但我无法得到这个错误。

如果我不使用 openmp 标志，程序会运行，但它不会被视为 openmp 程序。

谢谢

对英特尔论坛的快速浏览表明，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

我有同样的问题，搜索后，有人建议这种方法，对我有用。只需在调用 ifort 时添加此选项：

 -openmp -fpp -auto

该问题可能是由于未链接到 mp 库引起的。
