Re: test project example -help with builddir configuration

Interesting;

So in Oren's m4 file this is the target referenced for DX_CONFIG

#     .PHONY: doxygen-run doxygen-doc $(DX_PS_GOAL) $(DX_PDF_GOAL)
#
#     .INTERMEDIATE: doxygen-run $(DX_PS_GOAL) $(DX_PDF_GOAL)
#
#     doxygen-run: @DX_DOCDIR@/@address@hidden
#
#     doxygen-doc: doxygen-run $(DX_PS_GOAL) $(DX_PDF_GOAL)
#
#     @DX_DOCDIR@/@address@hidden: $(DX_CONFIG) $(pkginclude_HEADERS)
#         rm -rf @DX_DOCDIR@
#         $(DX_ENV) $(DX_DOXYGEN) $(srcdir)/$(DX_CONFIG)

I think it calls doxygen in the process of building target PACKAGE.tag; 
but it reference the srcdir relative to current.

the value of DX_CONFIG is set on the initialization command present in 
configure.ac:



AC_DEFUN([DX_INIT_DOXYGEN], [

# Files:
AC_SUBST([DX_PROJECT], [$1])
AC_SUBST([DX_CONFIG], [ifelse([$2], [], Doxyfile, [$2])])
AC_SUBST([DX_DOCDIR], [ifelse([$3], [], doxygen-doc, [$3])])

 I don't think changing the file name is a good idea in 
DX_INIT_DOXYGEN  so how would I change the target call above to make a 
builddir/doxygen.cfg and then execute it?

My thought was a conditional command

# if [ "$builddir" != "$srcdir" ] ;
#         $(DX_ENV) $(DX_DOXYGEN) $(builddir)/$(DX_CONFIG)
# elseif [ "$builddir" == "$srcdir" ]
#         $(DX_ENV) $(DX_DOXYGEN) $(srcdir)/$(DX_CONFIG)
#fi

also a conditional AC_SUBST inside configure.ac that reflects the same 
choice to make a builddir config if needed but keep the doxygen.cfg 
@srcdir@ since that is the location of the files under inspection
but I haven't written a script in 5 years...so forgive my ignorance. 
Thoughts?

Thanks,

Dave
