在 MacOS 上使用 clang-15 在 FindTerminfo 中 CMake 错误

Question

我在我的项目中使用 llvm 并通过 cmake 找到它 find_package(LLVM REQUIRED CONFIG)。

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

它实际上是一个 well-known issue in clang-14 and greater.

临时解决方案是在你的项目中使用C语言。

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