您好,

我想知道是否有解决以下问题的方法。我在下面强调了:

SET(GW_SOURCE_FILES 
  module.c 
  module_imp.c 
  module_message.c
  module_config.c
  module_queue.c)

# Compiles the source files to create the shared library called dlg_gw.so
ADD_LIBRARY(dlg_gw SHARED ${GW_SOURCE_FILES}) 

# Link additional libraries to this
TARGET_LINK_LIBRARIES(dlg_gw gc srl ${APRUTIL})

# ISSUE: Now I want to create my executable using the same source files. module.c is where my 'void main(void)' is. 
# However, I have some functions in there which will also be part of the library.
# However, this will recompile the same source files all over again. I don't really like that behaviour.
ADD_EXECUTABLE(sun_gw ${GW_SOURCE_FILES})

# After the executable is created, link the libraries with it.
TARGET_LINK_LIBRARIES(sun_gw ${APR} driver dlg_gw dlg_sip dlg_ss7 dlg_isdn)

我希望你能看到上面的问题,因为我正在编译两次相同的源文件。一旦创建dlg_gw库。然后再次创建可执行文件sun_gw

我正在考虑取出'void main(void)'并将其放在一个名为runtime.c的新文件中,然后执行以下操作:

ADD_EXECUTABLE(sun_gw runtime.c)

但是上面要求我改变一些源代码。

非常感谢任何其他建议,

CMake 2.8.8中引入的“OBJECT”库类型可用于避免重复构建相同的文件。
