我正在尝试在我的程序中使用 live555 库。我使用 CMake 作为构建系统。我制作了这个 CMakeLists.txt :
aux_source_directory(. SRC_LIST)
include_directories("${PROJECT_SOURCE_DIR}/libs/live/BasicUsageEnvironment/include")
include_directories("${PROJECT_SOURCE_DIR}/libs/live/UsageEnvironment/include")
include_directories("${PROJECT_SOURCE_DIR}/libs/live/groupsock/include")
include_directories("${PROJECT_SOURCE_DIR}/libs/live/liveMedia/include")
link_directories("${PROJECT_SOURCE_DIR}/libs/live/BasicUsageEnvironment")
link_directories("${PROJECT_SOURCE_DIR}/libs/live/UsageEnvironment")
link_directories("${PROJECT_SOURCE_DIR}/libs/live/groupsock")
link_directories("${PROJECT_SOURCE_DIR}/libs/live/liveMedia")
add_executable(${PROJECT_NAME} ${SRC_LIST})
set(LIVE_LIBRARIES BasicUsageEnvironment UsageEnvironment groupsock liveMedia)
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS} x264 avcodec swscale ${LIVE_LIBRARIES})
编译/链接我得到了很多类似这样的错误:
/home/davide/program/libs/live/groupsock/libgroupsock.a(NetAddress.o):-1: In function `AddressPortLookupTable::AddressPortLookupTable()':
每个库都已编译。似乎这些库相互依赖，我必须将它们链接在一起或按特定顺序链接。有谁知道是否是这种情况？怎么做？
最佳答案
这不是因为 cmake 而是内部 live555 依赖项，它应该可以像这样修改顺序:
set(LIVE_LIBRARIES groupsock liveMedia BasicUsageEnvironment UsageEnvironment)
关于c++ - 使用 CMake 针对 live555 静态库进行编译，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19682453/
