[mythtv] Win32-Packager fails to compile QT4 (Was: Win32 port fails to compile Freetype)

[Andreas Mayer]

Michel,

line.

InterlockedCompareExchange in QT4 and the MingW includes. 
As I said before it appears that these problems are caused by recent mingw
installations.
Until now I did not find the time to find out what the real problem is,
however by using 5.1.3 mingw and using "previous" selection during
installation of mingw I was now able to finish compilation of mythtv and
mythplugins (both at r18962, all plugins).

First I had to change win32-packager.pl to use a build root other than
c:\mythtv because I have not enough space on c:
SDL and libvisual failed as described in wiki.
I had to change fftw-3.1.2 to fftw-3.2 because 3.1.2 was not available
anymore.
During qt4 build I had to change -llibmysql to -lmysql in
src\plugins\sqldrivers\mysql\mysql.pro
Configure for mythtv failed, I had to change --runtime-prefix to
--runprefix.
For compiler error "libs/libavcodec/pthread.c: include/sched.h:152,154
syntax error before "pid"" I had to insert #else typedef int pid_t; to
/mingw/include/sched.h:122  (see another post from this week), this appears
to be a bug in pthreads already fixed in current versions.
bswap.h had to be changed (see another post from this week).

For the plugins I used "configure --enable-all" and several (currently quick
and dirty) changes.

After installation of the generated package Qt mysql driver was not found
because qsqlmysqld4.dll was missing in bin\sqldrivers for the default debug
build and plugins were not loaded because they were installed to
bin\mythtv\plugins and not to lib\mythtv\plugins.

Until now I was able to start mythtv-setup, mythbackend and mythfrontend on
my laptop running xp.

For testing mythfrontend I connected to my existing opensuse 11.0 x86
backend.
None of the plugins (I'm most interested in mythmusic and mythgallery)
currently work for me although they did work (at least partialy) in previous
build attempts.
Neither watching live tv nor watching recording currently works for me (did
partialy work with previous builds as well).
For live tv I'm currently able to hear audio but screen stays black.
I'm getting error messages "VideoOutputD3D Error: StretchRect() failed"

I'm not sure how to proceed from here ...
First of all I need to find out why the windows port does not work for me
although others have had success.
Next I will try to contribute by finding out why building with mingw 5.1.4
does not work and why the plugins do not work.

Greetings,
