162650 - have a autoconf macro to get compile and link flags from mozilla-config

Status: RESOLVED WORKSFORME

(SeaMonkey :: Build Config, enhancement)

Description

[Axel Hecht]

as more apps use Mozilla components, we should have support for autoconf.
Adding chak, as I think this is a MRE issue.

I created a mre.m4, based on nspr.m4, which can be used like this:

AM_PATH_MRE(1.0.1,[xpcom js], HAVE_MRE=1,HAVE_MRE=0)
if test -z "$HAVE_MRE"; then
 echo "MRE not found"
else
 echo $MRE_CFLAGS
 echo $MRE_LIBS
fi

not sure if this is really MRE, so macro names might need a change.

It would be better if Chris reviewed the patch since i'm not all that familiar
with autoconf...thanks

The m4 code looks correct but I'm also concerned about the naming since nothing
about the output of the mozilla-config script is really MRE specific.

Why is this necessary? Can't you just use pkg-config?

Comment 5

[Axel Hecht]

Maybe we could, of course that depends on the availability of pkg-config.
I found it for cygwin, solaris and linux. Fink has it on 
http://fink.sourceforge.net/pdb/package.php/pkgconfig.

So the other question is, which .pc do we need? I bet there should be at least a
mozilla-xpcom-glue.pc or so, but is that enough? mozilla-mre.pc to get to 
mredir          = $(libdir)/mre/mre-$(MOZILLA_VERSION)
mrelibdir       = $(mredir)/lib
?

Which .pc(s) you need depends on what your actual dependencies are. The ones
currently available are here:

  <http://lxr.mozilla.org/mozilla/source/build/unix/>.

If you have dependencies that are not satisfied by any combination of those,
then probably another one needs to be added.

Having every package under the sun install it's own autoconf macro is a solution
that has been obsoleted by pkg-config. pkg-config has a high likelihood of being
installed or available for any POSIXy system that might get a reasonably fresh
version of Mozilla installed on it, because there are lots of packages that
already use it. I recommend WONTFIX for this bug.

pkg-config worksforme, mozilla-config doesn't expose a whole lot more than the 
current set of .pcs. (LiveConnect is the only exception that I see.)
I bet that not shipping pkg.m4 isn't worth mentioning, that obviously ships with
pkg-config.
