与MIC.o文件的链接错误 在将MIC应用程序的源代码与英特尔C++ ICPC编译器链接时，我得到了一个错误。

英特尔icc/2013-64版本：

这是什么

__gnu_cxx::__atomic_add_dispatch(int*, int);

需要与链接。

我不进行原子添加。唯一的事情是一个pragma卸载\u传输targetmic:0->因此，它生成一个MIC.ofile@SScholl，但是您发布的链接器错误表明此函数丢失。您可以发布用于生成代码的命令吗？这将有助于找出哪里出了问题。谢谢。@footh只是在openmp中使用ipcp，错误取决于编译.o文件的顺序。但当然没有依赖性。
