c6000 8.3.8 编译器在编译使用C++14 STL库的OpenMP工程时报内部错误

当编译只有一个main.cpp文件的OpenMP工程时，如果代码中使用的STL库，编译器会报内部错误，语言标准为C++14，器件为c6678。main.cpp代码如下：

#include <vector>

struct ABC{float *data;
}

void test_fxn(const std::vector<ABC>& obj)
{float * data=obj[0].data;
}

报如下错误：

This is caused by a defect in the TI EABI C/C++ Parser.
TI Customer Support may be able to suggest a workaround to avoid this.

Upgrading to the newest version of the compiler may fix this problem.

编译选项为：

-mv6600 --include_path="C:/Users/YuHaoxin/Documents/CCS_Workspace/test" --include_path="C:/ti/ccs930/ccs/tools/compiler/ti-cgt-c6000_8.3.8/include" -g --c99 --c++14 --diag_warning=225 --diag_wrap=off --display_error_number --multithread --openmp

如果去除"–openmp"选项，则编译通过。

我的项目需要同时用的Openmp和C++14的STL，请问该如何解决这个问题？

请问是否有参考过下面的帖子？https://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_CCS_3307005

你好，我参考过这个帖子，但是实际情况时我在需要使用openmp的源文件在编译时报错，无法单独为这个文件关闭–openmp选项。请问您能重现这个错误吗，这个是不是编译器的bug？

,

Shine：

是否有尝试过上面帖子里的办法？CCS allows for File Specific Options. With that you can enable –openmp at the project level, and then manually remove –openmp on specific C++ source files which cause the compiler crash.

haoxin yu：

您好，我尝试了，关闭–openmp后确实可以编译通过，但是报错的函数正好需要使用openmp，这个选项在这个文件上无法关闭，请问有什么解决办法吗？

Shine：

openmp不支持C++，对于C++的代码不能使用-openmp编译。

haoxin yu：

我想你说得不对，我测试后确认openmp支持C++。另外，我测试后发现只要直接或间接包含utility头文件就会触发这个错误，包括自己定义的模板类。

, after testing, I found that this error will be triggered as long as the utility header file is included directly or indirectly. In addition,

我看到您在e2e上也发帖了。建议再跟帖问一下产品线工程师，或者我帮您跟帖也可以，最好把可以编译的C++贴一下作参考。https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1040786/tms320c6678-c6000-8-3-8-compiler-report-internal-error-when-building-an-openmp-project-with-c-stl
