Legacy gsdx for opengl 3.05?

[i30817]

Until a few months ago, the gsdx plugin worked (very slowly of course, but still good enough to play games like FFXII international at 10 fps with the inbuilt frameskip) in linux on this very old portable (2007-2008). Now with larger extension requirements, the daily build fails at opening any game.
PPSSPP system information says my opengl version is 3.05

I've read that gsdx will have a legacy version. My question is if the legacy will work on my version of the opengl api and this kind of old hardware as it was until recently?

the failure messages on the window:

I'm not building (using the ppa). I guess I will have to wait for the release, build it myself (which i frankly think will go pear shaped) or go bother the ppa guy to do a legacy package?

[gregory38]

What mesa version do you have?

[i30817]

glxinfo | grep "OpenGL version"
OpenGL version string: 3.0 Mesa 10.5.9

[gregory38]

And are you sure that you don't have an extra plugin that you need to select.

Otherwise it might be a good idea to upgrade your driver.

[gregory38]

wait current GSdx require at least 3.3 even legacy

[i30817]

Yeah, the only gs plugin in the options is :
GSdx (GCC 4.9.2, SSE2) 1.1.0 [libGSdx]

Something which might be important is that the directory in that these plugins are put is a read only system one, probably because of the package.
/usr/lib/games/PCSX2

[gregory38]

you can copy the plugin into your home directory and configure PCSX2 to use them.

[i30817]

If it does require 3.3, that must be recent(ish) because i remember using the emulator to play in January I think? 5 months or so.

And i think the package recipe in the ppa is just not building the legacy one. Really if it really requires 3.3 always it won't work anyway. Maybe i should see if it's possible to downgrade from a ppa and pin the package.

[gregory38]

3.3 check is quite old. Srange. Honestly try to install a more recent Mesa. It might be enough.

[i30817]

Ah. I'd probably have to upgrade the whole system to a new ubuntu release which would be a pain 😓

Thanks for the help anyway.

[gregory38]

Yes but I vaguely remember that first version that support gl 3.3 was sandy bridge. So far the error messages are 2 sw extensions that ought to work with any hardware. So upgrading mesa is the best solution.

[i30817]

Mmm... yeah:

glxinfo | grep "Core Profile"
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.5.9

[gregory38]

So you're good only miss mesa 11.2 ;) I didn't know that it was working for those old gpu.

[i30817]

Time to close this, i know what i have to do, thanks for the clarification.
