GtkGLExt-CRITICAL on Suse 10.2 and other issue

[pla7er]

Hi,

First of all, kudos to the author of the emulator! IMO, none of the other PSX emulators currently compare with the ease of use and quality of pSX! Great job, really!

Now, back to the issues.

I used v1.11 for Linux release. I'm running Suse 10.2, and when I run the pSX from console, the following happens:

#1: Every time I run the pSX, it prompts to look for the BIOS file, even though the BIOS file is under the bios folder. When I find and select the SCPH1001.bin file, it leads to the issue #2 (below).

#2: After the bios file has been selected, the app prompts to select a language - I choose English (btw, this happens every time also and I though it should ask for it once and then write it to ini file) and the app crashes with the following messages:

(pSX:6048): GtkGLExt-CRITICAL **: gtk_widget_get_gl_context: assertion `GTK_IS_WIDGET (widget)' failed

(pSX:6048): GtkGLExt-CRITICAL **: gtk_widget_get_gl_window: assertion `GTK_IS_WIDGET (widget)' failed

Can you download and try the last WIP version:

psxemulator.gazaxian.com/pSX_wip.tar.bz2

and see if that also crashes in the same way. If it does please run it under gdb:

gdb ./pSX
run

then after it crashes type:

bt

and paste the results here.

I tested the emulator on Debian Sid and it crashed with the same message as pla7er.

Here are the results from GDB:

Otherwise, keep up the good work!

Okay, this appears to be a video driver issue.

Try upgrading your nvidia or ati glx driver. Someone else had this issue with the WIP and it was fixed by upgrading to the latest nvidia driver.

[TryA]

Yes, you were right: i've updated my nvidia driver (I have a GeForce MX 4000) and it works smoothly now!
Thanks a lot!

I'm still getting the GtkGLExt-CRITICAL message, but now not until I close the emulator - and I'm not getting any crashes. In the last WIP, I got the message on starting the emulator - but again no crashes.

I'm using the ATI 6.33.6 driver in Ubuntu 6.10; since I installed it, the emulator has been running beautifully, although not as fast as in Windows yet...

[pSX Author]

Yeah - I noticed that warning on my system too - its not a serious problem though - you can ignore it.

I already have the latest Nvidia driver for my video card, so I assume the driver version should not be a problem. I've got Geforce FX 5900XT.

Ran the psxemulator.gazaxian.com/pSX_wip.tar.bz2 with gdb:
the app launched, selected English, asked to locate the bios file - located it, then the pSX window froze with the following message in the console:

Failed to read a valid object file image from memory.

Well, this is the same problem - other people have fixed it by upgrading their driver (see above).

Which version of the driver are you using?

Yes, I saw that.

The driver I'm using:

Linux Display Driver - x86

Version: 1.0-9746
Operating System: Linux x86
Release Date: December 21, 2006

www.nvidia.com/object/linux_display_ia32_1.0-9746.html

Maybe you can try downgrading? I'm using 1.0-8776, and don't experience this.

I need the latest driver for other things.
Anyway, no a problem, as the Win build seems to have run under Wine pretty decent...
