构建llvm ClangTool

Question

我设法建立了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,我收到以下错误:

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)

我目前的CMakeLists.txt是:

set(LLVM_LINK_COMPONENTS support)

add_clang_executable(loop-convert
  LoopConvert.cpp
)

target_link_libraries(loop-convert
  clangTooling
  clangBasic
  clangASTMatchers
)

Answer 1

你需要使用关键字签名target_link_libraries; 有效地,您需要添加PRIVATE到target_link_libraries您的语句中CMakeLists.txt:

target_link_libraries(loop-convert PRIVATE
  clangTooling
  clangBasic
  clangASTMatchers
)

这是因为add_llvm_executable使用这样的签名而你不能在CMake中混合它们.
