mga_vid don't compil

[Gregoire Favre]

Hello,

I am new to this list, I have looked with google to find a solution, but
the one I found just hang my computer when I load the mga_vid module...

With the current CVS, without any patch, it doesn't compil :

My gcc is :

Reading specs from /usr/lib/gcc/i586-mandrake-linux-gnu/3.4.1/specs
Configured with: ../configure --prefix=/usr --libdir=/usr/lib --with-slibdir=/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --enable-long-long --enable-__cxa_atexit --enable-clocale=gnu --disable-libunwind-exceptions --enable-languages=c,c++,ada,f77,objc,java --host=i586-mandrake-linux-gnu --with-system-zlib
Thread model: posix
gcc version 3.4.1 (Mandrakelinux (Alpha 3.4.1-3mdk)

Does anyone have a solution ?

Thank you very much,

you forgot the most important information: that you are using
a 2.6 kernel.

It's not supported yet, work ongoing.
Put there was a patch on -dev-eng recently which might be applied.

No, it's in the log of the compilation :-)

My message wasn't clear : I have tested three patches from -dev-eng but
then my computer crash when I insmod the module...

http://zebra.fh-weingarten.de/~maxi/html/mplayer-dev-eng/2004-06/msg00517.html

and

http://georgi.unixsol.org/programs/mga_vid-kernel-2.6.diff

Both without success

I am sorry, I was thinking the above message should already have gone in
some way to the CVS . I'll then wait a little more :-)

Thank for your answer,
