并行程序给出错误“对_Kmpc_ok_to_fork的未定义引用"； [英] Parallel program giving error "Undefined reference to _Kmpc_ok_to_fork"

问题描述

我正在尝试在Linux上编译OPENMP fortran代码.我大约有230个子例程.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

I am trying to compile the OPENMP fortran code on linux. I have around 230 subroutines. The code I used to compile the code is as follows: 1) At first I compiled each subroutine with the following command

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

然后，所有子例程现在都有一个单独的目标文件.

Then all the subroutines have now a separate object file.

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

2) Then I tried to compile the object files to the executable by the following command

ifort *.o -o myprogram

我遇到以下错误:

我正在使用Intel 13 Composer来编译程序.我不知道如何在libiomp5md中使用链接.

I am using intel 13 composer to compile the program. I didn't know how to use link with libiomp5md .

请帮助我摆脱此错误.我尝试了几次，但无法收到此错误.

Please help me get rid of this error. I tried several times but I couldn't get this error.

如果我不使用openmp标志，则程序会运行，但不会被视为openmp程序.

If I don't use the openmp flag the program runs but it doesn't treat as openmp program.

谢谢

推荐答案

对英特尔论坛的快速扫描表明，您可能还需要在第二个命令上使用 -openmp 选项，以使它能够链接到OpenMP库.

A quick scan of the Intel forums suggests you may need the -openmp option on the second command as well, to cause it to link against the OpenMP libraries.

您可以通过谷歌搜索 __ kmpc_global_thread_num
