Two ways, depending on how clean the separation is between
the header you create and the sources you are compiling.
If the header is *NOT* derived from the sources you compile,
then add this to Makefile.am:
mumble.h : <whatever>
<whatever-you-gotta-do> -o $@
Otherwise, do this:
$(OBJLIST) : mumble-stamp
mumble-stamp :
<whatever-you-gotta-do> -o mumble.h
touch mumble-stamp
I also generally add this:
GENSRC = mumble.h
gen : $(GENSRC)
mumble.h : <whatever>
<whatever-you-gotta-do> -o $@
so I can decide to type, "make gen" and be sure my
generated files are up-to-date. It is ugly. Especially
when the automated dependencies come along and decide
that your objects depend on mumble.h and mumble.h depends
on your sources and you modified your sources, so it
must be time to regenerate the mumble.h and recompile everything.
Maybe we need a ``.dependignore'' a la ``.cvsignore'' :-)
