It's actually got better performance than the Mesa with (limited hardware acceleration) was on the PS2.

make linux-cell

the following error message appear

could anyone help me to solve
thanks a lot

Does mesa-cell driver only work with the associated demos or can you test other apps with it? I was wondering if the driver would permit you to use the opengl features of some emulators e.g. scaling in fceultra.

All of my attempts at using it with anything more than simple demos and screensavers have failed, though I haven't tried it with everything like emulators using OpenGL. Anyone else?

It might be worth to build it again from git - maybe things have progressed in the interim?

Just tried the latest version of the mesa-cell driver on YDL 6.1 -- seems to be a little faster now ...

EDIT: oh, one more thing -- to compile I had to install two RPMs from Cell SDK 3.1:

cell-libs-devel-3.1-1.ppc.rpm
spu-simdmath-devel-3.1-1.ppc.rpm

I didn't go through the whole installation of Cell SDK 3.1, just extracted the .iso and installed using rpm -ivh packagename (located in cellsdk3.1/rpms directory).

cell-libs-devel is "IBM Licensed Materials" so can't redistribute I guess:

Looks like it can be compiled without the Cell SDK on Ubuntu 8.10 intrepid ibex (newer version of gcc):

I noticed that too. I thought they had dumped the project all together.

I don't appear to have the same driver as you....

You got a link to the version you have it appears the one I have used is the older version.

EDIT You updated mesa to 7.3 also? I found it on sourceforge....

Yeah, me too!

I just downloaded the latest code using git as described in the first post.

I done the same billb. I just used the git link from your post on page 1 to download the src and then installed accordingly. Notice it shows different renderer for mine then yours does!

Mine shows as!

Seems you have a different renderer and newer mesa library than me. Wonder how the older library can run with higher fps than the newer. I am curious how ours is so different when we used the same install process from the same src!

Are the gears spinning smoothly on your screen when you run ./glxgears ?

billb I am uploading a video to youtube to illustrate it, It will show you better then I can tell ya.

I seen 202 FPS off the back slowed to about 176 FPS then I fullscreen it and get over 65 FPS in full screen. The video is better proof then my word, I'll get the link up soon as it uploads about 1/3 uploaded now!

A simple yes or no would suffice ...

Does it now work with opengl enabled emulators yet? Think it'll be fast enough?

Good question ... I haven't tried building any of the emulators against this version -- I'm assuming this would be necessary. It would certainly be very interesting if it works, but I have my doubts that it will. Also, I believe I tried running the SPE scaler tool (which uses just one SPE, I believe) to zoom in and the glxgears test slowed to a crawl. But if it was working and accelerated to an acceptable speed you wouldn't need to use the SPE scaler tool anyway.
