wine hangs in ddraw/d3dtexture.c (d3dtexture_create)

[Michael Schlüter]

Hi,

the whole yesterday I was hunting a problem when staring a program with
wine. Now I'm at a point I don't know what to do next. May be somebody
can give me an hint?

Here are the last lines of the trace+ddraw output:

The appropriate source code:

ENTER_GL();
        if (surf->mipmap_level == 0) {
            glGenTextures(1, &(private->tex_name));
            if (private->tex_name == 0) ERR("Error at creation of OpenGL texture ID !\n");
            TRACE(" GL texture id is : %d.\n", private->tex_name);
            private->__global_dirty_flag = (at_creation == FALSE ? SURFACE_MEMORY_DIRTY : SURFACE_MEMORY);
            private->global_dirty_flag = &(private->__global_dirty_flag);
        } else {
            private->tex_name = ((IDirect3DTextureGLImpl *) (main->tex_private))->tex_name;
            TRACE(" GL texture id reusing id %d from surface %p (private at %p)).\n", private->tex_name, main, main->tex_private);
            private->global_dirty_flag = &(((IDirect3DTextureGLImpl *) (main->tex_private))->__global_dirty_flag);
        }
        LEAVE_GL();

A printf showed me, that the call of glGenTextures didn't come back.
That's strage because d3dtexture_create and glGenTextures are called a
lot of times before without problems? If I delete glGenTextures it works
but...

Bye, Michael
