[mythtv-users] OS X 10.7 Xcode 4.1

[Matthew Smith]

Thanks to the people who responded to my interest in successful builds
on OS X 10.7. Glad to hear it is possible.

A couple of days ago, I mentioned I would share my experience once the
mac arrived. Here it is.

I downloaded and compiled the various dependencies and cloned the 0.24
fixes branch using git.

Configure ran through smoothly (./configure --disable-distcc
--qmake=/usr/local/Trolltech/Qt-4.7.3/bin/qmake --enable-mac-bundle)
but make died building what looks to be a deinterlacing filter that
doesn't seem to like x86_64 (full error pasted below)

I noticed Jean-Yves Avenard suggested using the OS X 10.6 SDK and to
compile with "-compile-type=debug". I added that to my configure
command and got a build done.

Can anyone tell me what gets lost in terms of performance when
building MythTV with the compile-type=debug option? Do the builds up
on sourceforge get made with the same option?

Also, unfortunately, launching mythtv-setup.app failed with a Qt
error. Apparently, if you compile Qt with "-no-framework" on OS X, you
get a problem with qt_menu.nib  (see link
https://bugreports.qt.nokia.com//browse/QTBUG-5952 )

I guess I'll rebuild Qt with frameworks enabled tomorrow and see if
that fixes the .apps that get built for MythTV. However, after taking
a peak at the osx-packager script, I see Qt is built without
frameworks there, so I'm a little puzzled.

This is my first experience in the OS X world, so maybe someone can
tell me, do I even need to build Myth with the --enable-mac-bundle
option, or am I just as well off skipping it?

For info, here's the error where make died building Myth without the
compile-type=debug option:
