[sokol_app]: opengl context creation fails when attempting to create or attach to existing console

[EnokViking]

passing win32_console_attach OR create = true to sapp_run via sapp_desc when requesting an opengl context results in an erroneous state where context creation fails with the error: "WIN32_WGL_OPENGL_3_2_NOT_SUPPORTED: OpenGL 3.2 not supported by GL driver (ERROR_INVALID_VERSION_ARB) ./SokolApp.h, at line: 6642".

Oh, that is both weird and unexpected because those two things should be entirely unrelated to each other. I'll need to try and reproduce on my Windows machines.

Can you share a bit more information about your setup? At least Windows version and GPU vendor?

Hmm, I can't seem to reproduce the problem here (my config: Win10 Home 22H2, NVIDIA RTX 2070 driver version 528.24).

I used the clear-sapp sample, and added the following to the init() function:

    switch (sg_query_backend()) {
        case SG_BACKEND_D3D11: printf("Hello from D3D11\n"); break;
        case SG_BACKEND_GLCORE33: printf("Hello from GL\n"); break;
        case SG_BACKEND_METAL_MACOS: printf("Hello from Metal\n"); break;
        default: printf("???\n");
    }

...and changed sokol_main like this:

sapp_desc sokol_main(int argc, char* argv[]) {
    (void)argc;
    (void)argv;
    return (sapp_desc){
        //...
        .win32_console_create = true,
        .win32_console_utf8 = true,
    };
}

Do you have some more information for me which would help me identifying the problem?

PPS: same result on my laptop which has the same Win10 build, but an integrated Intel HD Graphics 520 GPU.

I was reluctant to post this issue since I'm binding from another language(beef) and figured I was just doing something wrong on my end which turned out to be the case so you can sleep well tonight. There was a size mismatch of 8 bytes between the sapp_desc i was passing into sapp_run and the expected data. I stepped into sapp_run and verified that like so:

The culprit ended up being sapp_logger, I had simply forgotten to add the userdata member and that didn't occur to me since I was just copy-pasting the structs and changing the types.. >> Sorry for having you verify this, but thanks for the sanity check.

Hmm, reminds me that there's this language bindings generator PR which I still haven't looked into yet (which needs a bit of work though):
