CMake：C编译器无法编译简单的测试程序。 令人惊讶的是，C编译器识别是未知的，但CXX是GNU 4.9.2

Question

我试图编译一个Thor库。 这取决于SFML。 编译SFGUI时也没有任何问题，SFGUI也依赖于SFML。 以前我使用完全相同的工具链。 一切都很好

CMake gui错误：

The C compiler identification is unknown
The CXX compiler identification is GNU 4.9.2

It fails with the following output:

我尝试编译简单的int main(){} 。 gcc工作。 所有路径都符合预期。 （顺便说一下，我不使用DevCpp，它只是编译器的路径）。

我很惊讶，因为g ++有效，CMake能够显示识别但显然不适用于gcc

谢谢你的帮助

Answer 1

如果您不安装基本构建包，则会在Solus OS上显示该消息。

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

然后它工作正常。

Answer 2

现在通过将我的GCC从4.9.2升级到4.9.3来修复。 没有崩溃的问题，但显然有一个与C ++ 11标准相关的更改，我需要手动编辑CMakeLists.txt以在编译任何库时将标志-std=c++11更改为-std=gnu++11和任何程序

MinGW / CxxTest奇怪的错误

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，并摆脱了所有的配置问题。 可能它是一个损坏的installaton或一些旧版本的bug
