Hello,
I have an external build process that produces a linker script that I
must use in my CMake project. I must leave the external build as-is.
I'm using gcc in Linux.
I must relink my application built with CMake if the linker script
changes. I'm trying to do this in a simple macro and it's not
working. I do not see a first class way to specify arbitrary link
dependencies, so I'm setting the dependency indirectly to the
application sources.
# setup link dependencies for _app_name
MACRO( DEPEND_ON_LD _app_name)
GET_TARGET_PROPERTY( _srcs ${_app_name} SOURCES )
SET_SOURCE_FILES_PROPERTIES( ${_srcs} PROPERTIES OBJECT_DEPENDS
/full/path/to/linker_script.ld )
ENDMACRO()
If I touch the linker script file, my app does not relink.
Any help is very much appreciated! Perhaps there is a cleaner way to do this?
Thanks,
-steve
