Compiling trunk under OS X 10.6 (Snow Leopard)

Hi all,

I gave this a try today after upgrading, including Xcode. I blew away
the build directory to start from scratch. Had to manually fetch the
mysql code, and then found that the Qt libraries don't support this
version of OS/X when compiling. It's been out for a day - I can't
understand why it's not fixed 8^). The frontend built under 10.5 runs
just fine.

The earliest Qt that tries to support snow leopard seems to be 4.5.1.
I patched osx-packager to pull down 4.5.2 (copy the 4.4 stuff & add an
-opensource option to the configure) which works OK until it gets to
libQtSql where it dies on unresolved symbols. It looks like the mysql
client library is targeting x86_64 but the Qt only supports i386.
Passing i386 to mysql's configure doesn't help. Or, I'm doing it wrong.

I'll poke around until I lose interest which will probably happen
soon. Also, I'm not sure how well myth gets along with Qt 4.5.

My mistake. It was picking up old Qt libraries I had in /Developer/
Tools. Removing those and giving a gratuitous -platform macx-g++-64 to
configure got Qt 4.5 to build for me.

Next up was libmad which failed because its configure doesn't check
for 64 bit environments. I added a --build x86_64 and it built.

On to myth itself. Snow Leopard defaults to gcc 4.2 which doesn't know
about -Wno-long-double so I had to comment that out of settings.pro.
Now it's crapping out in h264.c with a bunch of "suffix or operands
invalid for `add'" errors on lines 5431, 5443, 7265 & 7277. There were
also a ton of assembler warnings in libswscale but I looked the other
way.

Nigel, are you interested in getting the build working on Snow Leopard
at this time? There's a #warning in qglobal.h that causes "Support for
this version of Mac OS X is still preliminary" to show on every single
gcc run. Maybe they're trying to tell us something.

Only slightly. Other problems are more important.

Stupid question from me ... do 0.21-fixes / trunk binaries compiled
under 10.5.x work under 10.6, or is it just the compiling that's a
problem under 10.6?

Thanks - been clutching my copy of 10.6 since Friday, and reluctant to
upgrade if running myth under OSX is going to be a problem.

Stephen mentioned that a 10.5-built frontend runs just fine on 10.6.

It was only 3 lines below your quote!! :)

Thanks George - mea culpa!. That's what happends when you try to
quickly catch up after being away all weekend and trying to decide
whether to pop that Snow Leopard DVD in quickly....

I jumped in without even my usual carbon copy backup to an external
drive and everything went fine. Only hitch so far is firefox has been
crashing anytime I go near its Window menu. It seems to be related to
one of the add-ons so I've been avoiding that menu.

I just pulled down a 21591 build from the sniderpad and it works OK
for me. 1080 video is jerky but 720 and lower plays great. In the
menus it's dropping network connections like crazy but I don't know if
that's myth or my network. I get a ton of "MythSocket(19a4e3c0:36):
readStringList: Error, timed out after 30000 ms." lines.

What do you see in /var/log/system.log? Or, better yet, fire up the
console app and watch the system and console messages fly by as you
run the frontend (those two files receive what usually goes to /var/
log/mythtv on Linux).

I assume you looked in Console.app for output?

(or, tried MythFrontend.app/Contents/MacOS/MythFrontend -v most,extra)

Sadly, I don't get that far with Qt4.5.2 on 10.6.1:

Qt 4.5.3 fails in the same way. Did you see this one?

Nope, I can get it to build all the way. Starting from scratch I
reapplied my changes to osx-packager.pl and got it to go as far as
myth's h264.c where it fails on an assembler problem, basically the
same on as the last time I posted to this thread. I haven't written
any assembler code in decades but I'll see what I can come up with.

You can pick up my changes at http://files.nassas.com/osx-packager.pl.
There's the addition of the qt-4.5.3 bit (the -arch x86_64 is
important) and an architecture option for libmad.

What hardware are you building on? I'm on a unibody macpro 17" with
10.6.1 & xcode with the iPhone sdk not that it makes a difference.
It's odd that the compile line you quoted targets 10.4 and i386 while
mine looks like this:

g++ -c -I/Users/george/dev/mythosx/Snow/.osx-packager/build/include -I/
Users/george/dev/mythosx/Snow/.osx-packager/build/include/mysql -fno-

I../../../include/QtCore -I../../../include/QtXml -o .obj/release-
static/qbuffer.o ../../corelib/io/qbuffer.cpp

Oh, I had to comment this line out of myth's settings.pro:

macx:QMAKE_CXXFLAGS += -Wno-long-double

because snow leopard's gcc doesn't know about the option. I don't know
enough about qmake to do an O/S version test.

I thought 64 bit was now the GCC default?

Early MacBook (Core Duo, not Core2 Duo), so NOT 64 bit.

Ideally, it would be a GCC version test in MythTV's configure,
but I'm not sure about the need for that flag anyway.

Sorry, I guess it was trying to run the perl script instead of serving
it up. Makes sense I suppose. I changed it to http://files.nassas.com/osx-packager.txt
but I guess it won't be useful since we have 32/64 bit differences.

> I thought 64 bit was now the GCC default?

It looks like configure defaults to x86 (i386) so I have to override
it on my machine to be compatible with the 64 bit mysql libs.

> Early MacBook (Core Duo, not Core2 Duo), so NOT 64 bit.

Hmph. That explains why your results are different from mine but not
why your build is failing. IIRC the last time I tried building myth I
forced mysql to build i386 and Qt was able to build to the end so it
can happen. Is it possible you have old Qt libraries in /Developer or
somewhere? That bit me once.

I don't know if I'll ever come up with anything useful on that
assembler failure but in general would you like to make the packager
build things universal or move to specific settings for 64 bit snow
leopard?

I purged .osx-packager/build/include more thoroughly,
and got past Qt. Now up to the libavcodec build errors.
This change (basically reverting [20843], adding back
some earlier MMX )
may get you further:

Universal, but if that isn't possible, new arguments
to osx-packager to specify ppc/32bit/64bit.

Ideally, configure would test all of this for us, but it is
probably a bit hard when Qt might never support both 32 & 64bit
builds from the one "install" of its libraries and headers.
