Thanks for the reply Harry-
I'm fairly sure that I will need to lipo together the builds for
Musicbrainz' Picard.
So - in your experience what are all the options that I must set after
a fresh src install to have a 10.5 setup building binaries for 10.4?
Also, does anyone know how UB deals with endian-specific code? Does
the c-preprocessor run twice and eval all the #ifdef big_endian (or
whatever the define/macro would be)? Or is there some other way to do
this that wouldn't require two runs of the cpp.
Thanks
Tim

Do you know if its possible for me (on leopard) to build x86 code (all

Short of physical access to an intel 10.4 install, is there anything I
can do?
I am the OSX bundle maintainer of avidemux (I maintain others too
but via other ways). I build my avidemux binaries and dependent libs
as universal ones on Leopard (using macports for all necessary libs)
and the bundle (including binary and necessary libraries) is used on
Tiger as well as Leopard. Note that avidemux is available as
macports package, but I build (b)leeding edge svn bundles. I need to
compile avidemux for i386 and ppc from svn trunk and "lipo merge"
them to make them universal.
The bundle contains some complicated libraries (glib, pango, cairo,
gtk and they are all built universal and without X11 (so native
aqua) via macports) and this works fine. (Two libs are not yet in
macports and I need to make ports as soon as I have time to do so,
but maintaining three packages and developing my own takes quite
some spare time)
Don't forget to use Reply All so the discussion goes to the list as
well. There are no guarantees that this will work, but the way to do
what you want would be to set universal_target to 10.4,
universal_sysroot to /Developer/SDKs/MacOSX10.4u.sdk, and
universal_archs to i386. Then build everything with +universal (best
to
add it to your variants.conf).
Also set x11prefix to /usr/X11R6; Leopard's X11 prefix /usr/X11 does
not exist on Tiger.
Thanks for the tip!
Has anyone tried this? Success/failure stories?
openssl failed for me when I tried it this way on Leopard. Switching
back to 10.5 and the 10.5 SDK fixed it.
90% builds OK.
Some other binaries and libraries fail to build this universal way:
gimp (now built as i386 aqua), sqlite3 (is a pain in the backside
anyway), subversion (svn), wxwidgets (wxMac), wine, libGLEW,
libOrbit, libSDL*, liba52*, libav*, libbonobo, libboost, libgnome,
libpoppler and some others.
I build these binaries/libraries with "sudo port <package> -
universal" as I have +universal (and -x11) in my variants.conf
Next to that: some libraries can be build universal as static libs,
but not as dynamic libs like x264 (can't remember the other one)
Also: some libs are so POSIX compliant that, when build via macports
on Leopard, they can't be used on Tiger. (lib)xvid is one. I need
to build that one manually.
Note: I mentioned in a earlier post in this thread that I have
# the SDK "sysroot" to use
universal_sysroot /Developer/SDKs/MacOSX10.4u.sdk
in my macports.conf. Technically speaking you can just as well use
the 10.5 SDK as that one builds for 10.4 too as long as you set the
deployment target to 10.4. I choose the 10.4 SDK as quite some
packages are not yet "10.5 SDK optimized" which led to some errors
(pango and gtk). The 10.5 SDK uses some "new stuff" that works fine
on Leopard but not on Tiger as most ports are actually linux based
and ported to Mac. Maybe they are already fixed but I did not check
yet.
