Is there another way to solve this kind of problem?
well, it's not clean, but you can process the headers on install. this could
be a provisional approach (i.e., kludge) while you make the interface platform
independent.
see below for petrify-headers. sample usage:
install-data-hook:
$(srcdir)/petrify-headers $(srcdir) $(pkginclude_HEADERS)
files=`ls *.petrified | sed 's/.petrified$$//g'`; \
for f in $$files ; do \
$(INSTALL_DATA) $$f.petrified $(DESTDIR)$(pkgincludedir)/$$f ; done
rm -f *.petrified
you will need to munge things slightly to fit your setup, or better yet, reel
in horror and run away run away!
