Can't run example 01

[dcharles525]

Not sure why but I can't get it to run any of the examples, however I can start gngeo with no game loaded.

Edit: I should also mention I am running Ubuntu 18.04

/examples/01-helloworld$  make gngeo
/usr/bin/ngdevkit-gngeo -b glsl --shaderpath="/mnt/6caf58d5-d873-41ac-930d-63ff042b1cad/Code/examples/shaders" --shader="qcrt-flat.glslp" --scale 3 --no-resize -i rom puzzledp

I wonder if the GLSL backend could be the cause of the crash here.
Can you try to run the example with the soft blitter instead and see if the crash goes away?

/usr/bin/ngdevkit-gngeo -b soft --scale 3 --no-resize -i rom puzzledp

Also, in any case, could you give me a stack trace of where the crash is happening, with:

gdb --args /usr/bin/ngdevkit-gngeo -b glsl --shaderpath="/mnt/6caf58d5-d873-41ac-930d-63ff042b1cad/Code/examples/shaders" --shader="qcrt-flat.glslp" --scale 3 --no-resize -i rom puzzledp
run
bt

@dciabrin The first command worked! Thank you!

Here is the stack trace:

Good to know.

Here is the stack trace:

Ok that definitely looks like the the way gngeo uses threads doesn't play nicely with the nvidia GL driver. It's going to be painful for me to replicate as I don't have an nvidia card around. But just to confirm the theory, can you give me a stack trace of all the threads running at the time:

 gdb --args /usr/bin/ngdevkit-gngeo -b glsl --shaderpath="/mnt/6caf58d5-d873-41ac-930d-63ff042b1cad/Code/examples/shaders" --shader="qcrt-flat.glslp" --scale 3 --no-resize -i rom puzzledp
run
thread apply all bt

I suspect that the thread that created the GL context is not the one which performs the rendering, or something along those lines.

No worries if it can't be fixed, assuming I can use the other command it should work just fine for me exploring the Neo Geo. :)

This is the output I got:
