Hi Alan, When you added symcat.h to bfd-in.h, you have to install symcat.h along with bfd.h. You also need to add $(INCDIR)/symcat.h to BFD_H_DEPS in bfd/Makefile.am. You may also update bfd/dep-in.sed to remove symcat.h. Could you please fix bfd/Makefile.am and rebuild bfd/Makefile.in? Thanks. H.J.
