I don't have much experience compiling software from source so I'm
probably just missing something obvious, please bear with me. The
system specs are FC2, 2.6.10-1.771 (official kernel rpm), matrox G450.
I just compiled mplayer CVS for the first time and am trying to get
mga_vid together, with some limited success. So far I've tried
these versions:
mga_vid-2.6.10-2005-01-11.tar.gz
mga_vid-2.6.11-2005-03-06.tar.gz
The first does not compile smoothly:
[***@depijp mga-vid-2.6.10]# make mga_vid.ko mga_vid_test
make -C /lib/modules/`uname -r`/build
SUBDIRS=/usr/local/src/mga-vid-2.6.10 modules
make[1]: Entering directory `/lib/modules/2.6.10-1.771_FC2/build'

make[1]: Leaving directory `/lib/modules/2.6.10-1.771_FC2/build'
make: *** No rule to make target `mga_vid_test.c', needed by
`mga_vid_test'. Stop.
and then trying to modprobe it results in:
[***@depijp mga-vid-2.6.10]# modprobe mga_vid
FATAL: Error inserting mga_vid
(/lib/modules/2.6.10-1.771_FC2/misc/mga_vid.ko): Bad address
The second compiles but appears to install the module in the wrong
directory (/lib/modules/2.6.10-1.771_FC2/extra/mga_vid.ko instead of
/lib/modules/2.6.10-1.771_FC2/misc/mga_vid.ko) which causes modprobe
to be unable to find it. Fortunately moving it to modprobe's
expected directory fixes things.
I probably wouldn't have posted except for the fact that I only
figured this out as I was double checking my procedure while writing
this email, heh. In the process of trying to get this together I
encountered difficulty connecting to http://attila.kinali.ch/mga/ so
I tried a version that someone on the list posted,
http://flashdance.cx/tmp/mga-vid-2.6.11-2005-03-06.tar.gz (I think).
Running diff on it shows it to be exactly the same as the
http://attila.kinali.ch/mga/ sources I was able to get this morning
but the results were not... Previously the mga_vid.ko module would
not load if modprobed, but would load and run if insmod was pointed
to its fully qualified location. So I took a step back, decided to
try to compile a 2.6.10 mga_vid module which was when I found that I
could connect to http://attila.kinali.ch/mga/, wrote this email and
managed to get the 2.6.11 module working.
The only other factors that changed (to my knowledge) were that the
first time I compiled mga_vid (the flashdance version, oh what a
feeling <g>) I had yet to compile mplayer or install an mplayer rpm
on this partition. Also ldconfig was run a couple of times
subsequent to the initial mga_vid compile, thinking that it might
solve modprobe's problems. Other than that everything's pretty much
the same.
Anyway, mystery solved and I thought you'd want to know about the
FC2 mga_vid installation directory issue and that the other info
might possibly be helpful.

Barton
