编译llvm ClangTool [英] Build llvm ClangTool

问题描述

我设法构建了llvm和clang，现在我试图根据

I managed to build llvm and clang and now I am trying to create a ClangTool according to clang docs. But I am getting the following error when I am trying to build it:

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:

My current CMakeLists.txt is:

set(LLVM_LINK_COMPONENTS support)

add_clang_executable(loop-convert
  LoopConvert.cpp
)

target_link_libraries(loop-convert
  clangTooling
  clangBasic
  clangASTMatchers
)

推荐答案

您需要使用target_link_libraries的关键字签名；有效地，您需要在CMakeLists.txt的target_link_libraries语句中添加PRIVATE:

You need to use keyword signature of target_link_libraries; effectively, you need to add PRIVATE to the target_link_libraries statement in your CMakeLists.txt:

target_link_libraries(loop-convert PRIVATE
  clangTooling
  clangBasic
  clangASTMatchers
)

这是因为add_llvm_executable使用此类签名，并且您无法在CMake中将其混合.

This is because add_llvm_executable uses such signature and you can't mix them in CMake.
