Lỗi liên kết dụng cụ Cmake và clang (bên ngoài cây nguồn)

Question

Tôi đang cố gắng biên dịch RecursiveASTVisitor example of Clang bằng tệp CMake. Xây dựng dự án diễn ra tốt đẹp, tuy nhiên việc liên kết thực thi C++ không thành công với nhiều tham chiếu không xác định đối với các thư viện LLVM và Clang. Tôi đang xây dựng ví dụ bên ngoài cây tệp nguồn LLVM/Clang.

Đây là CMakeLists.txt của tôi (Tôi đang sử dụng FindClang.cmake and FindLLVM.cmake from this project):

cmake_minimum_required(VERSION 2.8.4) 
project(ifcount) 

set(CMAKE_MODULE_PATH 
    ${CMAKE_CURRENT_SOURCE_DIR}/cmake/modules 
    ${CMAKE_MODULE_PATH}) 

message(STATUS "CMAKE module path: ${CMAKE_MODULE_PATH}") 

find_path(LibClang_INCLUDE_DIR clang-c/Index.h) 
find_library(LIBCLANG_LIBRARY NAMES clang) 

find_package(LLVM REQUIRED) 
find_package(LLVM REQUIRED CONFIG) 
Find_Package(LLVM REQUIRED) 
include_directories(${LLVM_INCLUDE_DIR}) 
link_directories(${LLVM_LIB_DIR}) 

message(STATUS "Found LLVM ${LLVM_PACKAGE_VERSION}") 
message(STATUS "Using LLVMConfig.cmake in: ${LLVM_DIR}") 

find_package(Clang REQUIRED) 
find_package(Clang REQUIRED clangTooling libClang) 
include_directories(${CLANG_INCLUDE_DIRS}) 

### 
add_definitions(${LLVM_DEFINITIONS}) 
add_definitions(${Clang_DEFINITIONS}) 

add_definitions("-std=c++11") 
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${LLVM_COMPILE_FLAGS} -Wall -fno-rtti -g -std=c++11 -D__STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS") 

set(SOURCE_FILES main.cpp) 
add_executable(ifcount ${SOURCE_FILES}) 

llvm_map_components_to_libnames(llvm_libs support core irreader) 

target_link_libraries(ifcount ${llvm_libs} ${LLVM_LDFLAGS} ${CLANG_LIBS}) 

Và đây là kết quả:

Bất kỳ trợ giúp hoặc mẹo nào sẽ được đánh giá cao. Cảm ơn.

Tôi đã kết thúc bằng cách viết lại CMakeLists.txt dựa trên this particular file.

Dưới đây là file sửa đổi làm việc:

cmake_minimum_required(VERSION 2.8.4)
