自己裸机移植RTThread到STM32F407开发板上，想用C/C++混合编程，出现了以下问题
1.在C/C++下不添加“—cpp11“时显示
` Build target 'Target 1' compiling main.c.....\rt-thread\T.h(14): error: #20: identifier "class" is undefined class CTIM ..\rt-thread\T.h(15): error: #65: expected a ";" {..\rt-thread\T.h(28): warning: #12-D: parsing restarts here after previous syntax error };..\rt-thread\T.h(39): warning: #1-D: last line of file ends without a newline #endifUser\main.c: 2 warnings, 2 errorscompiling T.cpp...T.h(39): warning: #1-D: last line of file ends without a newline #endifT.cpp: 1 warning, 0 errors".\Obj\Template.axf" - 2 Error(s), 3 Warning(s).Target not created.`
2.添加”—cpp11“之后显示
}

查过百度和官方论坛，没找到问题的解决方法，想问问各位怎么解决
这个我是已经添加了的
c语言包含的头文件不可以有
class, c的语法里没有‘类’。。。参见 https://blog.csdn.net/weicao1990/article/details/53462644
解决了，谢谢
请问您是怎么解决的？@帮大忙了
@做我喜欢
extern"C"包裹的部分是C语言的代码，C++不能用写在extern"C"修饰的内容里。
