 If this patch generates static libraries I don't see a problem.
 It might even be used to generate one statically linkable libsimgear 
 file instead of 17 different libraries. But that is open for discussion.
With libtool all you have to do to have it generate only static libraries is
to specify

libblah_blah_la_LDFLAGS = -static

in the Makefile.am.  This is what the patch does... You then want to replace all the 
link-time references (blah_LDADD = ../libblah/blah.a) with (blah_LDADD = 
../libblah/blah.la).

PATCH for Parallel make on SimGear Flightgear (Re: [Flightgear-devel] Fixes for parallel/SMP make compilation)

Libtool just has better dependency handling than straight Automake.  You can tell 
libtool to make static libraries only, which I have done.

The patches are up at http://noir.kain.org/fg/, against SimGear-0.3 CVS and 
FlightGear-0.9 CVS as of 05 Dec 2002 16:03:11 -0600 or so.

[Flightgear-devel] Fixes for parallel/SMP make compilation

[Kain]

I've libtoolized the makefiles for current CVS for SimGear and FlightGear.  This 
allows GNU make to properly handle the dependencies for SMP (parallel) compile.

This naturally speeds up compiles significantly.  Does anyone want the diffs?
