[gentoo-dev] KDEMultimedia and GCC 3.1

[Justin T.]

Heya,

Quick note that KDEMultimedia will have problems compiling (at least by me and 
some others I think) because of problems in mpeglib.  It appears that there 
are updates to the two files required to get this to compile under GCC3.1.  

Since I have never created a patch myself, I thought that I would just pass on 
where to find the information on this so somone can take a look into it and 
see if this is a valid fix :)

There are two files that need to be updated or patched, during the build they 
are at:

/var/tmp/portage/kdemultimedia-3.0.1.20020604/work/kdemultimedia-3.0.1/mpeglib/lib/util/render/dither2YUV/rgb2yuv16.cpp
/var/tmp/portage/kdemultimedia-3.0.1.20020604/work/kdemultimedia-3.0.1/mpeglib/lib/util/render/dither2YUV/rgb2yuv32.cpp

The information and diffs can be found at:

http://webcvs.kde.org/cgi-bin/cvsweb.cgi/kdemultimedia/mpeglib/lib/util/render/dither2YUV/rgb2yuv32.cpp
http://webcvs.kde.org/cgi-bin/cvsweb.cgi/kdemultimedia/mpeglib/lib/util/render/dither2YUV/rgb2yuv16.cpp

I hope that this will help anyone else that is having the same problem :)

Well... that takes me to the next error...

decoderBaseObject_impl.cpp: In member function `int 
DecoderBaseObject_impl::fillArts(long unsigned int, float*, float*)':
decoderBaseObject_impl.cpp:369: unrecognizable insn:
(insn 1087 979 1089 (set (reg:SI 297)
        (ashift:SI (reg/v:SI 63)
            (const_int 3 [0x3]))) -1 (nil)
    (nil))
decoderBaseObject_impl.cpp:369: Internal compiler error in extract_insn, at 
recog.c:2132

I found out there is a patch for this problem on the web (here is a link with 
more info), however it was already applied...:

http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=6497

So... where that leaves me now who knows....time to relax again I think :)

PS - I just recently installed the new 1.3b... the only problems I had so far 
were with Xfree (had to hand make and then merge) and kdemultimedia.  
Everything else went smoothly.  Just have to say that it is amazing what is 
happening with Gentoo :)

Thanks,

Justin T
