我正在尝试在我正在进行的项目中使用新的Boost.Log库.该项目是用CMake构建的.我收到链接错误声称链接器遇到了对Boost.Log的未定义引用
Linking CXX executable main
CMakeFiles/main.dir/main.cpp.o: In function `main':
main.cpp:(.text+0x30): undefined reference to `boost::log::v2s_mt_posix::trivial::logger::get()'
我有一个简单的hello world测试,但没有出现这些错误.如果我链接Boost.Log库会导致它产生未定义的引用错误？
main.cpp中:
#include <boost/log/trivial.hpp>
int main(int argc, char* const argv[]) {
BOOST_LOG_TRIVIAL(info) << "Hello World";
}
的CMakeLists.txt:
CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
FIND_PACKAGE(Boost 1.54 COMPONENTS log REQUIRED)
FIND_PACKAGE(Threads)
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})
ADD_EXECUTABLE(main main.cpp)
TARGET_LINK_LIBRARIES(main ${Boost_LOG_LIBRARY} ${CMAKE_THREAD_LIBS_INIT})
编辑:来自cmake和make的详细输出
