Can't compile libavcodec in mythtv (v6754)

Dear all,

I have some problems compiling mythtv (version 6754). At the moment I'm
stuck while compiling libavcodec.

My OS is Mandrake 10.1 with GCC 4.0.0...

---
ccache gcc -c -pipe -march=pentium4 -w -O3 -Wall -Wno-switch
-fomit-frame-pointer -D_REENTRANT -DPIC -fPIC -DMMX -Di386
-D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DPREFIX=\"/usr/local\"
-DHAVE_AV_CONFIG_H -D_LARGEFILE_SOURCE -DHAVE_XVMC -DQT_NO_DEBUG
-DQT_THREAD_SUPPORT -DQT_SHARED -I/usr/lib/qt3/mkspecs/default -I. -I..
-I../.. -I/usr/lib/qt3//include -o dsputil_mmx.o i386/dsputil_mmx.c
i386/h264dsp_mmx.c: In function 'h264_h_loop_filter_luma_mmx2':
i386/dsputil_mmx.c:618: error: can't find a register in class

make[1]: *** [sub-libavcodec] Error 2
make[1]: Leaving directory `/home/tingjie/src/mythtv/libs'
make: *** [sub-libs] Error 2
----

And if I manully take out "-march=pentium4 -O3" in the makefile, I hit
another error at "i386/fdct_mmx.c".. And here I'm stuck..

Any pointers will be appreciated.Thanks.

Tj

Your errors show that you are _not_ compiling that revision.

Thanks for helping me.

Forgive me if I made any mistakes, I never used subversion before...

I run "svn update" from my mythtv sources directory, and I got the
following:
At revision 6754.

I then do a "make distclean"
and then:
"./configure \
--disable-audio-arts --disable-audio-jack --disable-lirc \
--disable-joystick-menu --disable-firewire --disable-ivtv \
--enable-dvb --enable-xvmc --disable-xvmc-vld
and then "make".
After a while, I got that "error: can't find a register in class
'GENERAL_REGS' while reloading 'asm'" error message.

Did I miss anything?

BTW, how can you tell I'm not running revision 6754? I will do a fresh
checkout and try again...

Thanks.

Regards,
Tj

PS: I also tried with the "--disable-xvmc" and still got the same results.

Dear Issac, and all,

Did a fresh checkout of head and still doesn't work.

When I checked out a older copy: "svn co
http://cvs.mythtv.org/svn/trunk/mythtv -r {2005-06-29}". That gave me
revision 6733 and everything compiled without a hitch.

Me suspect the "Ffmpeg resync. Shouldn't break anything, I don't think."
commit broke something on my machine.

Nobody getting the same problem?

Regards,
Tj

Re: Can't compile libavcodec in mythtv (v6754) [In reply to]

I did an update this morning (10 hours ago) 6752
compiled fine after a distclean.
note that distclean doesnt do a real distclean as the config.mak and
config.h files are not deleted.
I posted a patch a while ago that does this if you are interested.
cheers

I see the same thing (when I saw it initially, I did the same thing I always
do, go add -O2 and see if it works, it does). h264 is disabled with another
hack already, it looks like the last ffmpeg sync relocated much of the h264
mxx routines off into h264dsp_mmx.c, the most important change was that back
in 6468 h264_h_loop_filter_luma_mmx2 was implemented as #if 0 // code #endif
a highly optimized implementation that might be considered anew.

I get the same compile error - Using Fedora Core 4 with GCC 4.0

Everything worked fine until I did a fresh update using the new svn
repository today.

well though.
