CMake:C编译器无法编译简单的测试程序.令人惊讶的是，C编译器标识未知，但CXX是GNU 4.9.2 [英] CMake: The C compiler is not able to compile a simple test program. Surprisingly C compiler identification is unknown but CXX is GNU 4.9.2
问题描述
我试图编译Thor库.这取决于SFML.我在编译SFGUI时也没有任何问题，这也取决于SFML.以前，我使用完全相同的工具链.一切正常
I tried to compile a Thor library. It depends on SFML. I didnt had any problem with compiling SFGUI which also depends on SFML. Previously I used exactly the same toolchain. Everything worked fine
CMake gui错误:
CMake gui errors:
The C compiler identification is unknown
The CXX compiler identification is GNU 4.9.2

我尝试编译简单的int main(){}.海湾合作委员会的作品.
所有路径均符合预期. (顺便说一句，我不使用DevCpp，它只是编译器的路径.)
I tried compiling simple int main(){}. gcc works.
All paths are as intended. (Btw I don't use DevCpp, its just the path to the compiler).
我很惊讶，因为g ++可以工作，CMake可以显示标识，但显然不能显示gcc
I am surprised because g++ works, CMake is able to display identification but apparently not for gcc
感谢您的帮助
推荐答案
现在通过将我的GCC从4.9.2升级到4.9.3修复了.不再有崩溃的问题，但是显然与C ++ 11标准有关，并且我需要手动编辑CMakeLists.txt以在编译任何库和任何程序时将标志-std=c++11更改为-std=gnu++11
Fixed now by upgrading my GCC from 4.9.2 to 4.9.3. No more problems with crashing, however apparently there was a change related to C++11 standard and I need to manually edit CMakeLists.txt to change flag -std=c++11 to -std=gnu++11 when compiling any library and any program
切换/更新MinGW发行版解决了所有问题.我尝试将编译器更新为7.2 +/8.0 +版本，并摆脱了所有配置问题.可能是安装损坏或某些较旧版本的错误
Switching/updating MinGW distro solved all problems. I tried updating the compiler to 7.2+/8.0+ versions and got rid of all confiuration problems. Likely it was a corrupted installaton or some older version bug
