OSMesa on Windows?

Hi,

It seems that building GLFW with OSMesa on Windows is currently not supported.
Is there a specific reason (beyond available time and manpower)?
Is there any work in progress related to this task?

Boris.

I’ve not myself tried building GLFW with OSMesa support but the win32 code has support for OSMesa contexts:

github.com

glfw/glfw/blob/05dd2fa2986c37e7aee3cba917b1d02a3a189390/src/win32_window.c#L1398-L1404


else if (ctxconfig->source == GLFW_OSMESA_CONTEXT_API)
{
    if (!_glfwInitOSMesa())
        return GLFW_FALSE;
    if (!_glfwCreateContextOSMesa(window, ctxconfig, fbconfig))
        return GLFW_FALSE;
}

Have you tried building with OSMesa support? Note that there may be a documentation error, and you may need to use GLFW_USE_OSMESA and not _GLFW_OSMESA:
