我正在尝试使用我的CMakeLists.txt中的以下代码将CMake 2.8.6链接到boost :: program_options
FIND_PACKAGE(Boost COMPONENTS program_options REQUIRED)
INCLUDE_DIRECTORIES (${Boost_INCLUDE_DIR})
ADD_EXECUTABLE (segment segment.cpp)
TARGET_LINK_LIBRARIES (segment ${Boost_LIBRARIES})
find命令似乎成功但将错误的目录传递给链接器.该包实际上是:
`/usr/lib64/libboost_program_options-mt.so.5`
但CMakeFiles/segment.dir/link.txt列出以下内容:
/cm/shared/apps/gcc/4.4.6/bin/c++ CMakeFiles/segment.dir/segment.cpp.o -o segment -rdynamic /usr/lib64/lib64/libboost_program_options-mt.so.5 -lpthread -lrt -Wl,-rpath,/usr/lib64/lib64
注意lib64路径中的额外内容.此外,路径前面的-l标志似乎缺失.
运行CMake时,它报告它正确找到包,并且该{$Boost_LIBRARIES}变量似乎列出了正确的库:
Boost found.
Found Boost components:
program_options
${Boost_LIBRARIES} - optimized;boost_program_options-mt-shared;debug;boost_program_options-mt-shared-debug
生成的CMakeCache.txt文件以:
//The directory containing a CMake configuration file for Boost.
Boost_DIR:PATH=/usr/lib64/boost
//Boost include directory
Boost_INCLUDE_DIR:FILEPATH=/usr/include
这似乎是正确的.但是当运行make时它使用上面link.txt中的路径,我得到错误:
make[2]: *** No rule to make target `/usr/lib64/lib64/libboost_program_options-mt.so.5', needed by `segment'. Stop.
make[1]: *** [CMakeFiles/segment.dir/all] Error 2
