We need to cross-compile stock kerberos 5 1.0 in an cross-development
environment where the environment's includes and libraries already
include a *different* GSSAPI library from the one included in the krb5
distribution. This essentially means that we have to tack on -I
options pointing at the cross-development includes at the *end* of
CFLAGS, not at the beginning.
Unfortunately it appears that:
1) the default .c.o rule is set in each Makefile.in, not in
config/pre.in or config/post.in
2) CFLAGS is set in each Makefile.in
3) Several of the Makefile.in's define CFLAGS as
CFLAGS=$(CCOPTS) $(DEFS) -I....
so the local includes come in last; in order to accomplish this we
will have to whack all the Makefile.in's, which is a bit annoying..
I sure hope I'm not missing anything blindingly obvious, but it looks
as if we're going to have to whack all the CFLAGS= lines to include a
$(CCENDOPTS), or else reorder the definitions to sort the options
including `-I's to the beginning..
Anyone see an easier way out of this mess?
