我的项目中有一个可执行文件和一个共享库。共享库使用 boost 库。可执行文件使用 olny 共享库。

tilenet/             <-- Project
   ttest/            <-- Test (executable)
      CMakeLists.txt
   tilenet/          <-- The shared library
      CMakeLists.txt
   CMakeLists.txt    <-- Root CMake-file

根 Cmake 文件:

cmake_minimum_required(VERSION 2.6) 

project(tilenet)

set(Boost_USE_STATIC_LIBS        OFF)  # I've already tried ON
set(Boost_USE_MULTITHREADED      ON)
set(Boost_USE_STATIC_RUNTIME    OFF)


find_package(Boost 1.49 COMPONENTS system filesystem REQUIRED)

include_directories(${Boost_INCLUDE_DIRS})

add_subdirectory(test)
add_subdirectory(tilenet)

测试/CMakeLists.txt

add_executable(ttest test.cpp)
target_link_libraries(ttest tilenet ${BOOST_LIBRARIES})

tilenet/CMakeLists.txt

include_directories("include")
set(tilenet_src "src/tilenet.cpp" ...)

add_library(tilenet SHARED ${tilenet_src})
target_link_libraries(tilenet 
            ${SFML_LIBRARIES}
            ${BOOST_LIBRARIES}
            )

(我剪掉了一些不重要的东西)

在 Windows 上它工作正常(但我在没有 CMake 的情况下使用 VisuelStudio),但在 linux 上我得到以下链接错误:

../../lib/libtilenet.so: undefined reference to `boost::filesystem3::path_traits::convert(wchar_t const*, wchar_t const*, std::string&, std::codecvt<wchar_t, char, __mbstate_t> const&)'

collect2: error: ld returned 1 exit status
make[2]: *** [../bin/ttest] Error 1
make[1]: *** [test/CMakeFiles/ttest.dir/all] Error 2
make: *** [all] Error 2

我已经尝试了很多与给定选项的组合,但我无法链接它。你知道我哪里出错了吗?这是我第一次认真使用 CMake :)

CMake 变量区分大小写,FindBoost 模块将 boost 库设置为名为 的变量Boost_LIBRARIES,而不是BOOST_LIBRARIES.

如果您在两次通话中替换为,它应该可以正常工作${BOOST_LIBRARIES}${Boost_LIBRARIES}target_link_libraries

有关 FindBoost 模块的完整信息,请运行:

cmake --help-module FindBoost
