MacOS 上使用 clang-15 在 FindTerminfo 中出现 CMake 错误

Question

我在我的项目中使用llvm并使用cmake的

find_package(LLVM REQUIRED CONFIG)

找到它。

配置失败并显示消息：

[cmake] CMake Error at /Applications/CMake.app/Contents/share/cmake-3.23/Modules/Internal/CheckSourceCompiles.cmake:44 (message):
[cmake]   check_source_compiles: C: needs to be enabled before use.

[cmake] 
[cmake] 
[cmake] -- Could NOT find Terminfo (missing: Terminfo_LINKABLE) 
[cmake] -- Configuring incomplete, errors occurred!

如何解决？

Answer 1

这实际上是 clang-14 及更高版本中众所周知的 问题 。

临时解决方案是在项目中使用C语言。

project(test LANGUAGES C CXX) # instead of project(test LANGUAGES CXX)
