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

Question

我试图编译一个 Thor 库。这取决于 SFML。我在编译也依赖于 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：

The C compiler identification is unknown
The CXX compiler identification is GNU 4.9.2
Check for working C compiler: E:/Programs_Portable/Dev-Cpp/minGW32/bin/gcc.exe
Check for working C compiler: E:/Programs_Portable/Dev-Cpp/minGW32/bin/gcc.exe -- broken

It fails with the following output:

我尝试编译简单的 int main(){}。海湾合作委员会工作。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++ 可以工作，CMake 能够显示标识，但对于 gcc 显然不行

感谢您的帮助

Answer 1

现在通过将我的 GCC 从 4.9.2 升级到 4.9.3 来修复。没有更多的崩溃问题，但是显然有一个与 C++11 标准相关的更改，我需要手动编辑 CMakeLists.txt 以在编译任何库和任何时将标志 -std=c++11 更改为 -std=gnu++11节目

编辑：Switching/updating 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+ 版本并解决了所有配置问题。可能是安装损坏或某些旧版本错误

如果您没有安装必要的构建包，Solus OS 上会显示该消息。

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.

您必须安装软件包，使用

sudo eopkg it -c system.devel

然后就可以正常工作了。
