[mythtv-users] mmx complilation problem

[Matthew Laird]

In trying to fix the seg fault problem with mythmusic I'm upgrading to the
latest CVS of everything as suggested.  However now I receive a new
problem in compilation:

gcc -c -pipe -O2 -march=i586 -mcpu=i686 -fmessage-length=0 -fPIC -w -Wall
-g -O3 -DPIC -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64

I found the thread:
http://www.gossamer-threads.com/archive/MythTV_C2/Dev_F10/Weird_avcodec_compile_problem_P96721/

of the mailing list and as you can see -O is in there.  Does anyone have a
work around for this problem?  Thanks.
