'bug' in mythtv register use?
|
|
Hello all.
On my new SuSE Linux 8.2 setup, mythtv won't compile, it keeps giving
this error:
gcc -c -pipe -O2 -march=i586 -mcpu=i686 -fmessage-length=0 -fPIC
-DNO_DEBUG -w -O3 -DHAVE_AV_CONFIG_H -I.. -D_FILE_OFFSET_BITS=64

A bit of searching on google got me this:
http://lists.debian.org/debian-gcc/2002/debian-gcc-200207/msg00094.html
Another suggested that removing PIC from the compilation should work
just fine. I'm trying to see if I can get that to happen right now:
http://lists.debian.org/debian-gcc/2002/debian-gcc-200207/msg00089.html
As you can see, it only seems to happen in libavcodec.
.. Okay, it seems everything compiles if i remove -fPIC from the
Makefile in the libavcodec catalog. At least that's a way around it for
now. Next is to see if it also works :)
Well, either the lack of -fPIC broke something or more things are
problematic with GCC 3.3:
g++ -c -pipe -O2 -march=i586 -mcpu=i686 -fmessage-length=0 -fPIC
-DNO_DEBUG -Wall -W -O6 -march=pentiumpro -fomit-frame-pointer

-I/usr/lib/qt3/include -o nuppeldecoder.o nuppeldecoder.cpp
nuppeldecoder.cpp: In function `void
release_nuppel_buffer(AVCodecContext*, AVFrame*)':
nuppeldecoder.cpp:399: error: `assert' undeclared (first use this

nuppeldecoder.cpp:399: error: (Each undeclared identifier is reported
only once for each function it appears in.)
make[2]: *** [nuppeldecoder.o] Fejl 1
make[2]: Leaving directory `/home/martin/CVS/mythtv/MC/libs/libmythtv'
make[1]: *** [sub-libmythtv] Fejl 2
make[1]: Leaving directory `/home/martin/CVS/mythtv/MC/libs'
make: *** [sub-libs] Fejl 2
That seems to indicate some code needs altering in the future to work on
modern systems. Maybe it will even help stability?
I'm not sure what to do about this...
