Years ago I set up a series of makefiles and bash scripts to build both a support library for kernel modules and my own kernel modules. Now years later, I don't recall much about how all this works but it has until moving to 5.15 (from 5.10. kernels). Although, there was an issue with it not supporting libraries at some upgrade point, but this list helped me with a patch so it would build the .a libraries and link with them. Looking at the makefile for building the library it has a note that I needed to set up a fake obj-m for it to actually build the library. So what I have is: # Setup module name for kbuild obj-m:=junk.o junk-objs:=lib.a There is no reference to any junk_mod.c file, it appears kbuild automatically creates the junk-mod.c file itself. The problem is the build now fails due to the: ERROR: modpost: missing MODULE_LICENSE() in /.../junk.obj Is there some other makefile option to make kbuild set the MODULE_LICENSE() or perhaps ignore it since it's not needed in this type of case? Or should I take this junk.mod.c file and now modify it and then actually copy it over as the actual source to use to force the library to be created? Thanks!!
