Cmake和clang工具链接错误（源树之外）

时间：2014-09-11 08:20:06

标签： c++ cmake clang llvm llvm-clang

我正在尝试使用CMake文件编译RecursiveASTVisitor example of Clang。 构建项目进展顺利，但是链接C ++可执行文件失败了多个未定义的LLVM和Clang库引用。 我正在构建LLVM / Clang源文件树之外的示例。

这是我的CMakeLists.txt（我正在使用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})

这是输出：

我最终使用基于this particular file的重写CMakeLists.txt。

以下是修改后的工作文件：

)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-rtti -std=c++11")

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