VIA Epia Drivers (CX700M2) - No idea to deal with the Sources

[Rumo]

Hi,

i tried to build the latest available Driver (available at viaarena.com) for my Via-Epia-Platform (for Graphics).The kinds of errors displayed in the standard-out after calling make aren't easy to follow. A lot of stuff seems to be missing. Has anybody successfully build these drivers in the past ? I'm looking forward to receive an answer :-)

With best regards,

Rumo 

P.S.: My Distro is Verctorlinux 5.9

Rumo,

Do you have the source code for the kernel on your box? If you don't, you'll need it to build the drivers. You can download the source code from http://www.kernel.org/.

HTH some,
John

Hi John,

only to check that i'm understanding your post correctly:

I need the full Kernel-Sources for the Kernel-Version that's currently installed on my system ? Is that correct ? What do i have to do with the Kernel-Headers and stuff that are actually on my hdd ? Overwrite them ? Erase them ? Make a new Directory to store them ?

And what means HTH some ? :-)

Yes.

No. The headers from the kernel that was on your VL iso are needed so that programs requiring glib can reference them.

And what means HTH some ? :-)

HTH some = Hope this helps some. :-)

Hi John,

i checked my Distro right to realize, that the Kernel-Sources had already been installed. Again I read the Installation-Docs delivered with the Drivers Sources carefully. All Stuff that's needed is installed.

I started the compiler by calling a script named 'makedriver'. It fails. Theres trouble with a file named 'overlay.c'.

overlay.c: In function 'Upd_Video':
overlay.c:2799: warning: initialization from incompatible pointer type
overlay.c: At top level:
overlay.c:7450: error: expected identifier or '(' before '{' token
overlay.c:8790: error: expected identifier or '(' before '{' token
make: *** [overlay.lo] Error 1

I checked the Source included in this file an i found this:

(Starting at Line 7450)

#ifdef XFree86Server
unsigned long Upd_Capture0(PVIDDATA pVidData, RegionPtr clipBoxes, viaPortPrivPtr pPriv)
#elif defined(__KERNEL__)
unsigned long Upd_Capture0(PVIDDATA pVidData)
#endif /* XFree86Server */

I think, that none of the definitions was met. So there's no definition for the function. The compiler can't locate an
identifier (it's only a following '{') and throws an error. I tried to remove the ifdef-stuff an defined the function's head
the manual way. I tried both definitions. Both caused new errors. Any ideas ?

Hello,

after a few days I'm back again with a solution.

http://www.openchrome.org/

The openchrome-project provides a good and stable driver. Take the sources and just make them.
After installing the driver change the driver in your xorg.conf to "openchrome".

The MPEG2-Acceleration works fine, 3D-Acceleration works, too.
