Can't compile vertex shader of version 100.

The both error messages are empty (my program gets SDL and GL errors). It was working on amdgpu just fine.

What is exactly the error message?

You may download the ARM Mali offline shader compiler. That should produce the same compile results, provided you feed it with the correct version of the target MALIblob version (R6 P2?), and comprehensive error messages in your case.

The error message is empty. Maybe I'm receiving it the wrong way. But on amdgpu, it displays errors just fine. It may be truncated though.

[ghost]

SDLarch modified code for shader build.

GLuint GLPipeline::compileShader(unsigned type, unsigned count, const char **source) {
    if(video_status) return 0;
    GLuint shader = glCreateShader(type);
    glShaderSource(shader, count, source, NULL);
    glCompileShader(shader);

    GLint status;
    glGetShaderiv(shader, GL_COMPILE_STATUS, &status);

    if (status == GL_FALSE) {
        char buffer[4096];
        glGetShaderInfoLog(shader, sizeof(buffer), NULL, buffer);
        SDL_LogCritical(SDL_LOG_CATEGORY_ERROR, "Can't compile %s shader:", type == GL_VERTEX_SHADER ? "vertex" : "fragment");
        throw buffer;
        return 0;
    }

    return shader;
}

[ghost]

I didn't mentioned. After running the code some apps begin to segfault.

[ghost]

The offline compiler tells me that the compilation is succeeded.

[ghost]

Finally, the error: valgrind: m_transtab.c:2459 (vgPlain_init_tt_tc): Assertion 'sizeof(TTEntryC) <= 88' failed. I didn't mentioned, I have outdated dev SDL installed. Edit: it's valgrind's bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=838203

[ghost]

And more - official armbian SDL reports the same error I've seen two months ago. It's 'undefined reference to wl_egl_window_resize'. With every program.

[hor63]

It's 'undefined reference to wl_egl_window_resize'.

Mmmh, are you maybe running the FBDEV or Wayland mali.so against an X-Window application?

[ghost]

Maybe.

[ghost]

No. That is only defined in wayland mali but not in x11.

[ghost]

Holy... It seems that Armbian is now Wayland oriented. Any good desktop on Wayland working under Pi? Anyway, I broke my armbian installation so I cannot use apt. I'll return after reinstalling the whole stuff.

[ghost]

I'm back. Stock Armbian SDL won't work nor with X11 neither with Wayland. SDL built with OpenGL disabled and GLES2 enabled fails on both X11 and Wayland, with "Could not get EGL display". A.k.a "eglGetDisplay() failed" in es2_info.

[ghost]

Pathetic, Wayland itself tells that EGL is working, and running my app with sudo makes it fail even earlier. "No available video device".

[ghost]

Running the whole Weston as root, the error is "Could not get EGL display".

[ghost]

X11 SDL can't get GLES version with error 0, then can't compile vertex shader. Same story. But hey, for a second I had a window.

[ghost]

I've found what was wrong. It's -lGL in Makefile! So how could I link against GLES? -lGLESv2 would be fine?

Yes, that's fine. Just need to rebuild SDL without OpenGL and it would be fine. But I'll stay with gl4es, because I need other GL software to work without recompiling.
