Question

#include path
include_directories(
${PROJECT_SOURCE_DIR}/include
${HGE_INCLUDE_DIR}
${IKL_INCLUDE_DIR}
${BOOST_DIRECTORY}
)

#include all files
FILE(GLOB CORE_SRCS source/core/*.cpp)
FILE(GLOB TOOL_SRCS source/tools/*.cpp)
FILE(GLOB GAME_SRCS source/game/*.cpp)

#Making a compiled library
add_library(GAMECORE_LIBRARY ${CORE_SRCS} ${HGE_LIBRARY} ${HGE_HELPER_LIBRARY})

#add executable
add_executable(DemoGame ${GAME_SRCS})

##link executable to HGE lib
TARGET_LINK_LIBRARIES(DemoGame ${HGE_LIBRARY} ${HGE_HELPER_LIBRARY} ${IKL_LIBRARY} GAMECORE_LIBRARY)

if(BUILD_TOOLS)
add_executable(EntityTool ${TOOL_SRCS})
TARGET_LINK_LIBRARIES(EntityTool ${HGE_LIBRARY} ${HGE_HELPER_LIBRARY} ${IKL_LIBRARY} GAMECORE_LIBRARY)
endif(BUILD_TOOLS)

这是我现在的花言巧语...

I get a weird linker error for hgeGUI class
eg : DemoGame/source/core/GameMainMenu.cpp:74: undefined reference to `hgeGUI::hgeGUI()

This only happens when I try to compile the core files into a static library. When I add the executable with the CORE_SRCS and remove the dependencies on my current compiled library .. it will work fine..

我还尝试将 hgegui.cpp 文件复制到我的核心源目录... 并更改改为。

之后我的链接密码解决了问题, 但我得到分割断层断层, 但我猜连接前一步的文件是不对的。

Here s a link to their .h file

看起来你再次滥用了 ${HGE_Libriary}}/code>和${HGE_HELPER_Libriary}}/code>变量。



在 add_library  呼叫中,您包含构成该库的所有源文件。

在 target_link_library  呼叫中,指定连接目标时使用的图书馆或旗帜。

因此,如果 ${HGE_LIBRARY}}/code>和 ${HGE_HELPER_LIBRARY}}{/code>指定图书馆路径为 GAMECORE_LIBRARY 的依附关系,您需要做到:


add_library(GAMECORE_LIBRARY ${CORE_SRCS})
target_link_libraries(GAMECORE_LIBRARY ${HGE_LIBRARY} ${HGE_HELPER_LIBRARY})


依赖性是过渡性的,这意味着当您指定 GAMECORE_LIBRIARY 为 DemoGame  和 EntityTool 的依赖性时,CMake会承认 ${HGE_LIBRARY}}/code>和 ${HGE_HELPER_LIBRAY}{/code>也是依赖性,因此您可以将其从 goal_link_librarys  调来调  DemoGame  和 EntityTool  。
