i have one executable and one shared library in my project. The shared library uses boost library. the executable uses olny the shared library.
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
Root Cmake-file:
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)
ttest/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}
)

On windows it works fine (but there i use VisuelStudio without CMake), but on linux i get following linking errors:
在Windows上它工作正常(但我使用没有CMake的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&)'

../../lib/libtilenet.so: undefined reference to `boost::system::system_category()'

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

I've tried a lot of combinations with given options but i was not able to link it. Do you know where i made mistakes ? This is the first time i've used CMake seriously :)
我已经尝试了很多给定选项的组合,但我无法链接它。你知道我犯了哪些错误吗?这是我第一次认真使用CMake :)

CMake variables are case-sensitive, and the FindBoost module sets the boost libraries to a variable named Boost_LIBRARIES
, not BOOST_LIBRARIES
.
CMake变量区分大小写,FindBoost模块将boost库设置为名为Boost_LIBRARIES的变量,而不是BOOST_LIBRARIES。
If you replace ${BOOST_LIBRARIES}
with ${Boost_LIBRARIES}
in your two target_link_libraries
calls and it should work correctly.
如果在两个target_link_libraries调用中用$ {Boost_LIBRARIES}替换$ {BOOST_LIBRARIES},它应该可以正常工作。
