I have a large package with many subpackages.
each subpackage has its own configure.ac.
how do I generate aclocal.m4?
(I would rather not create a dozen separate aclocal.m4 files
- one for each subpackage)
I tried merging all the configure.in files in one:
src/autoconf/aclocal.m4 : $(wildcard src/m4/*.m4) $(addsuffix .in,$(CONFIGURES))
egrep '(AC_INIT|AC_PREREQ)' src/configure.in > configure.ac
cat $(addsuffix .in,$(CONFIGURES)) | egrep -v
'(AC_INIT|AC_CONFIG_HEADER|AC_OUTPUT|AC_CONFIG_FILE.*(Makefile|link\.sh)|_CANONICAL_|AC_PREREQ)'
>> configure.ac
echo AC_OUTPUT >> configure.ac
aclocal -I `pwd`/src/m4 --output=src/autoconf/aclocal.m4
$(RM) configure.ac
this results in these warnings and errors:
(aclocal (GNU automake) 1.9.5)
aclocal -I `pwd`/src/m4 --output=src/autoconf/aclocal.m4

make: *** [modules/regexp/configure] Error 1
this error is baffling. AC_CHECK_FUNCS_ONCE and AC_CHECK_HEADERS_ONCE
are not in aclocal.m4 -- why? (they are defined in src/m4/onceonly.m4,
but that file is not included in aclocal.m4).
So: how do I use aclocal.m4 with multiple subpackage configure.in?
thanks!

The difference between theory and practice is that in theory there isn't any.
