06:11 <fltrz> Im having trouble getting example 3 different example skeleton applications to run VSYNCed and render a triangle. I can get the VSYNCed hello-wayland-opengl-render-loop to work, but get errors trying to createVertexShader (returns 0), I also tried getting the open.gl example application (which uses GLEW) and succeed in getting a rectangle displayed, but then its not VSYNCed, and I also tried "propella" 's triangle_simple.c , but it fails

06:11 <fltrz> assertion on global.shells

06:31 <kennylevinsen> fltrz: maybe your vertex shader is broken?

06:56 <fltrz> the problem occurs before vertexshader, at glCreateShader(GL_VERTEX_SHADER)

06:57 <fltrz> kennylevinsen, I'm really considering just using the glxgears.c from mesa's xdemos dir, it runs vsynced and displays quads

08:37 <kennylevinsen> fltrz: you can take the opengl from there - it works the same.

08:38 <kennylevinsen> but maybe you're calling glCreateShader before the EGL context is created and made current? :/

08:39 <daniels> weston-simple-egl is generally the most bulletproof one to use

08:39 <daniels> which platform (in particular GPU/display drivers) are you on, and which compositor are you using?

09:38 <pq> yaay, nice to see wlb :-)

10:08 <fltrz> no, wasn't creating the EGL context before making current, as it was the same skeleton hello-wayland renderloop branch

10:09 <fltrz> anyway, I just went oldskool fixed pipeline, and now happily drawing quads, with glOrtho & glVertex2i, since I need pixel perfect checkerboards

10:10 <pq> fltrz, that sounds a lot like you were trying to call a gl function before making the context current.

11:23 <fltrz> derp, you guys were right

11:23 <fltrz> GLSL 150 is not supported. Supported versions are 1.00 ES, and 3.0 ES

11:25 <pq> fltrz, welcome to GL ES.

11:36 <fltrz> thanks, I just fixed the shader

11:36 <fltrz> thats the kind of trouble I get for duct-taping different tutorials together

11:37 <kennylevinsen> you learnt something though :)

19:56 <fltrz> pq, kennylevinsen I was thinking, for the problem I had, calling glFunctions before eglMakeCurrent, that sounds like something the -legl -lgles etc libraries could detect and error message about

21:22 <soreau> it might say something if you use debug version of mesa or set MESA_DEBUG but mesa isn't the only impl of these
