Hello Sam,
> >> So: how do I use aclocal.m4 with multiple subpackage configure.in?
if my yesterday's mail haven't convinced you, here are a few hints:
Normally, aclocal finds all necessary macros and concatenates them to
form aclocal.m4.
But if the macros live in subdirectory m4/ (and aclocal was called with
option "-I m4"), aclocal doesn't copy the whole file, it just creates a
line looking like:
m4_include([m4/mymacro.m4])
So you could find all macro files which are needed, copy them to one m4
directory, and aclocal.m4 would contain only such inlcude lines,
subdir/aclocal.m4 would contain
m4_include([../m4/mymacro.m4])
But how would you find the collection of all necessary m4 files?
Well, one possibility is to take all m4 files:
mkdir m4/
cp /usr/share/aclocal/*.m4 /usr/share/aclocal-1.9/*.m4 m4/
then run aclocal -I m4, aclocal -I ../m4, etc., in all subprojects.
And then remove unused m4 files, ie. those which are not referenced
from any aclocal.m4.
In the cvs version of Automake, aclocal has option --include, which
does this: all needed m4 files are copied to subdirectory m4/, and
aclocal.m4 contains only m4_include directives.
So you would just do
mkdir m4/
aclocal -I m4
(cd sub1; aclocal -I ../m4)
(cd sub2; aclocal -I ../m4)
...
To install the CVS version of automake, you have to install CVS version
of Autoconf first.
Or you can just take aclocal.in from CVS and incorporate this change
into automake-1.9.6/aclocal.in . CVS log should help you to extract
the exact patch that you need.
Good luck,
Stepan
