我通过这个添加了提升:
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
project(APP C CXX)
add_executable(APP src.cpp)
target_link_libraries(APP ${Boost_LIBRARIES})
当我编译源代码时,我得到了:
demo.cpp:(.text+0x3d3): undefined reference to `boost::system::generic_category()'
我检查了拼写(Boost_LIBRARIES vs BOOST_LIBRARIES),但没关系。
我使用包boost-devel在Fedora中安装了boost。
答案 0 :(得分:5)
查看source code,根据传递给Boost_LIBRARIES
的组件列表填充find_package
。尝试:
find_package(Boost REQUIRED COMPONENTS system)
您还应该使用导入的目标:
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
find_package(Boost REQUIRED COMPONENTS system)
# the call to include_directories is now useless:
# the Boost::system imported target used below
# embeds the include directories
project(APP C CXX)
add_executable(APP src.cpp)
target_link_libraries(APP Boost::system)
