A lot of the difficulty is in getting an autogenerated vnode_if.h while using a list of files to include in the module(from the common OpenAFS code) that's given as a list of object files. If there's already a vnode_if.h sitting around, I can just use OBJS and things progress quite nicely; however, if I have to get back to SRCS for the use of sys/conf/kmod.mk's vnode_if.h logic, I get this sort of build failure (full log attached) with the attached Makefile: gcc -I. -I.. -I../nfs [more includes and defines] -I/usr/devel/openafs/git/openafs/include/afs -I@/sys -Imachine -I. -I@ -I@/contrib/altq -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -fno-common -fno-omit-frame-pointer -mcmodel=kernel -mno-red-zone -mfpmath=387 -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -msoft-float -fno-asynchronous-unwind-tables -ffreestanding -fstack-protector -std=iso9899:1999 -fstack-protector -Wno-redundant-decls -Wsystem-headers -Werror -Wno-pointer-sign -o osi_crypto.o -c /usr/devel/openafs/git/openafs/src/afs/FBSD/osi_crypto.c /usr/devel/openafs/git/openafs/src/libafs/MODLOAD/../../afs/FBSD/osi_crypto.c vnode_if.h
gcc: cannot specify -o with -c or -S with multiple files
That last bit, "-o osi_crypto.o -c /path/to/osi_crypto.c /path/to/osi_crypto.c vnode_if.h" is quite troublesome. Any thoughts on what is causing those extra files to be listed would be greatly appreciated. (Comments on other issues in the Makefile are welcome, too -- it's still in pretty rough shape.)
I should note that though Makefile.common does define a osi_crypto.o target, "make -d A" reports: using existing source /usr/devel/openafs/git/openafs/src/afs/FBSD/osi_crypto.c
applying .c -> .o to "osi_crypto.o"
