CMake:C编译器无法编译一个简单的测试程序.令人惊讶的是，C编译器的标识是未知的，但CXX是GNU4.9.2

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

本文关键字：编译器 标识 未知 CXX GNU4 测试程序 编译 CMake 简单 一个      更新时间：2023-10-16

我试图编译一个Thor库。这取决于SFML。我在编译同样依赖于SFML的SFGUI时没有遇到任何问题。以前我使用完全相同的工具链。一切正常

CMake-gui错误：

我尝试编译简单的int main(){}。gcc有效。所有路径都符合预期。（顺便说一句，我不使用DevCpp，它只是编译器的路径）。

我很惊讶，因为g++工作，CMake能够显示身份，但显然不适用于gcc

感谢您的帮助

如果不安装必要的构建包，则消息将出现在Solus OS上。

CMake Error at /usr/share/cmake-3.12/Modules/CMakeTestCCompiler.cmake:52 (message):
The C compiler
   "/usr/bin/cc"
is not able to compile a simple test program.

您必须使用安装软件包

sudo eopkg it -c system.devel

然后它工作得很好。

现在通过将我的GCC从4.9.2升级到4.9.3来修复。崩溃没有更多问题，但显然有一个与C++11标准有关的更改，在编译任何库和任何程序时，我需要手动编辑CMakeLists.txt，将标志-std=c++11更改为-std=gnu++11

MinGW/Cxx测试异常错误

编辑：切换/更新MinGW发行版解决了所有问题。我尝试将编译器更新到7.2+/8.0+版本，并解决了所有的确认问题。很可能是一个损坏的安装程序或一些旧版本的错误
