OpenGL 2.1 / GLSL 1.2 requirement...

[MyTDT-Mysoft]

I know it doesnt exactly qualify as an issue, but i dunno other place to post about that.... so basically i have this 2004 laptop with an ATI card... that have OpenGL 2.0.5, and GLSL 1.1 ... as the scripts being used doesnt require GLSL 1.2 i converted them to GLSL 1.1, and now i don't get any more script compiling errros.... but what else that was changed that require OGL 2.1? because i'm only getting a white screen when running it now...

that have OpenGL 2.0.5

There is no OpenGL 2.0.5 version but I'm curious. Could you run glxinfo | grep 'version'.

as the scripts being used doesnt require GLSL 1.2 i converted them to GLSL 1.1

What did you changed?

what else that was changed that require OGL 2.1?

Basically everything: Switched from fixed pipeline to shader base pipeline. Now OpenGL 2.1 and OpenGL ES 2.0 use the same code.

Could you also define de OglError macro? This way it should print possible errors. Copy line 23 to 25 and run the app.

Your best option for now is to compile from the latest commit before the merge.

PS: I realize there is some trouble with config. I need to investigate to be able to repo.

2.0.5 is the internal version/revision by the card the offical is just
"OpenGL 2.0" the .5 is revision specific for the card... so nevermind that
:)

about the scripts.... i changed stuff like

vec3 AColor = texture2D(uTex1,vertexTexCoord1).rgb;

to...

vec3 AColor, ..., ...; //begin of the function like on older C
AColor = texture2D(uTex1,vertexTexCoord1).rgb;

so as GLSL 1.2 added initializers...
yeah, ok i can't compile mupen myself on windows... (because i dont want to
bloat my PC with cygwin or msvc 2013)... i only accept plain mingw hehe

but i will do that during this week... i will check the error on each GL
call since i have a proxy to the calls for a different purpose... anyway...
so i can find what else is failing without need to compile... (and i have a
fairly recent build that Richard compiled to me a week ago... so i could
try this new RICE :P)

mupen64plus-video-rice/src/OGLDebug.h

Line 23 in 7b357cf

#define OPENGL_CHECK_ERRORS { const GLenum errcode = glGetError(); if (errcode != GL_NO_ERROR) fprintf(stderr, "OpenGL Error code %i in '%s' line %i\n", errcode, __FILE__, __LINE__-1); }

?

@MyTDT-Mysoft, can I close this issue?

[MyTDT-Mysoft]

probabily @Narann, but could some effort be done to make it support glsl 1.1 instead of glsl 1.2?
i'm not confident with my shader ability, so didnt made a patch, as all i did was research into that direction to know the changes are minimal.

As you guess, we have limited resources. :(

Pull Request can be a good way to point what have to be changed and start discussions. It can be ugly as it point what would work with you so I can see what is problematic.

The point to change minimal requierement is to have a shared OpenGL 2.1/OpenGL ES 2.0 code.

The biggest part was to switch from fixed function pipeline to programmable shaders.

From a code perspective it's done, I now have to check on various hardware (Specially Raspberry Pi).

In your situation, all I can recommend is to get the code, fix it, even in a trashy way, clean what you can and do a pull request so we can talk about potential changes.

If we could support OpenGL 2.0 hardware without too much pain I would be happy. :)

Maybe it can be an easy fix, maybe not. For now I just can't do anything.

ok, i will try altough it will be hell to get it to compile on windows
without cygwin and msvc, but let's see...
