我设法构建了 llvm 和 clang，现在我正在尝试根据 clang docs 创建一个 ClangTool .但是当我尝试构建它时出现以下错误:

CMake Error at tools/clang/tools/loop-convert/CMakeLists.txt:6 (target_link_libraries):
  The keyword signature for target_link_libraries has already been used with 
  the target "loop-convert".  All uses of target_link_libraries with a target
  must be either all-keyword or all-plain.

  The uses of the keyword signature are here:

    * cmake/modules/LLVM-Config.cmake:105 (target_link_libraries)
    * cmake/modules/AddLLVM.cmake:771 (target_link_libraries)

我当前的 CMakeLists.txt 是:

set(LLVM_LINK_COMPONENTS support)

add_clang_executable(loop-convert
  LoopConvert.cpp
)

target_link_libraries(loop-convert
  clangTooling
  clangBasic
  clangASTMatchers
)

最佳答案

需要使用target_link_libraries的关键字签名；实际上，您需要将 PRIVATE 添加到 CMakeLists.txt 中的 target_link_libraries 语句:

target_link_libraries(loop-convert PRIVATE
  clangTooling
  clangBasic
  clangASTMatchers
)

这是因为 add_llvm_executable 使用了这样的签名，您不能在 CMake 中混合使用它们。

关于c++ - "uses of target_link_libraries must be either all-keyword or all-plain"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47737558/
