In this post I said I will get through the GLib Makefiles to add an enum type to GLib in a more sophisticated way.
In my other project, SWE-GLib I already used this method. The following two rules in Makefile.am create gswe-enumtypes.h and gswe-enumtypes.c.
gswe_enum_headers = headers-that-contain-enums.h
gswe-enumtypes.h: $(gswe_enum_headers) gswe-enumtypes.h.template
$(GLIB_MKENUMS) --template $(filter %.template,$^) $(filter-out %.template,$^) > \
gswe-enumtypes.h.tmp && mv gswe-enumtypes.h.tmp gswe-enumtypes.h
gswe-enumtypes.c: $(gswe_enum_headers) gswe-enumtypes.h gswe-enumtypes.c.template
$(GLIB_MKENUMS) --template $(filter %.template,$^) $(filter-out %.template,$^) > \
gswe-enumtypes.c.tmp && mv gswe-enumtypes.c.tmp gswe-enumtypes.c
$(GLIB_MKENUMS) is set in configure using
AC_PATH_PROG([GLIB_MKENUMS], [glib-mkenums])
This approach requires the GNU Autotools (you can get rid of it by changing $(GLIB_MKENUMS) to the path to glib-mkenums binary), and two template files, one for the header and one for the code. $(gswe_enum_headers) contains a list of all the header files that have enum types defined throughout the project.
