Clang with CLion：无法获取编译器信息
[英]Clang with CLion: Cannot get compiler information
问题描述
I tried to switch from gcc to clang in CLion by changing the Toolchains preference:
我尝试通过更改工具链首选项在 CLion 中从 gcc 切换到 clang：
But now the cmake fails with the following:但是现在 cmake 失败并显示以下内容：
Cannot get compiler information:
Compiler exited with error code 1: /usr/bin/clang++ -xc++ -DENABLE_EXTRAS ...
clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final)
Target: x86_64-pc-linux-gnu

Selected GCC installation: /usr/bin/../lib/gcc/x86_64-linux-gnu/7.3.0
If I manually run CMake in a terminal using -DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++ then it will work, only in CLion it doesn't.如果我使用-DCMAKE_C_COMPILER=/usr/bin/clang -DCMAKE_CXX_COMPILER=/usr/bin/clang++在终端中手动运行 CMake，那么它会起作用，只有在 CLion 中它不会。

Using clang 6.0 solves the problem:使用 clang 6.0 解决了这个问题：
-DCMAKE_C_COMPILER=/usr/bin/clang-6.0
-DCMAKE_CXX_COMPILER=/usr/bin/clang++-6.0
in CMake Options and go to File -> Invalidate Caches / Restart.在 CMake 选项中，然后转到文件 -> 使缓存无效/重新启动。 Everything works normal.一切正常。
