I'm pretty certain that 7.7 and 7.8 worked. <div class="gmail_quote">On Fri, Jun 1, 2012 at 1:40 PM, Brian Paul <<a href="mailto:brianp@vmware.com" target="_blank">brianp@vmware.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5">On 06/01/2012 12:29 PM, Andrew Cunningham wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi, I have built Mesa 8.0.3 on Windows(x64) to use as an optional GDI OpenGL renderer ( for when users connect over Remote Desktop). I am testing it as a "drop-in" replacement for the default OpenGL32.DLL, so after building Mesa, I copied the opengl32.dll and glu32.dll from the Mesa debug build into my application area. Unfortunately, the application "ASSERTS" the first time it tries to render a window, with info->BytesPerBlock==0. A quick look shows the format is MESA_FORMAT_NONE GLint _mesa_get_format_bytes(gl_format format) { const struct gl_format_info *info = _mesa_get_format_info(format); ASSERT(info->BytesPerBlock); ASSERT(info->BytesPerBlock <= MAX_PIXEL_BYTES || _mesa_is_format_compressed(format)); return info->BytesPerBlock; } opengl32.dll!_wassert(const wchar_t * expr, const wchar_t * filename, unsigned int lineno) Line 325 C > opengl32.dll!_mesa_get_format_bytes(gl_format format) Line 1556 + 0x26 bytes C opengl32.dll!_swrast_map_soft_renderbuffer(gl_context * ctx, gl_renderbuffer * rb, unsigned int x, unsigned int y, unsigned int w, unsigned int h, unsigned int mode, unsigned char * * out_map, int * out_stride) Line 191 + 0xd bytes C opengl32.dll!map_attachment(gl_context * ctx, gl_framebuffer * fb, gl_buffer_index buffer) Line 588 C opengl32.dll!_swrast_map_renderbuffers(gl_context * ctx) Line 667 C opengl32.dll!_swrast_span_render_start(gl_context * ctx) Line 851 C opengl32.dll!_swrast_render_start(gl_context * ctx) Line 869 C opengl32.dll!_swsetup_RenderStart(gl_context * ctx) Line 205 C opengl32.dll!run_render(gl_context * ctx, tnl_pipeline_stage * stage) Line 278 C opengl32.dll!_tnl_run_pipeline(gl_context * ctx) Line 163 + 0x12 bytes C opengl32.dll!_tnl_draw_prims(gl_context * ctx, const gl_client_array * * arrays, const _mesa_prim * prim, unsigned int nr_prims, const _mesa_index_buffer * ib, unsigned int min_index, unsigned int max_index) Line 525 C opengl32.dll!_tnl_vbo_draw_prims(gl_context * ctx, const gl_client_array * * arrays, const _mesa_prim * prim, unsigned int nr_prims, const _mesa_index_buffer * ib, unsigned char index_bounds_valid, unsigned int min_index, unsigned int max_index, gl_transform_feedback_object * tfb_vertcount) Line 424 C opengl32.dll!vbo_save_playback_vertex_list(gl_context * ctx, void * data) Line 312 C opengl32.dll!ext_opcode_execute(gl_context * ctx, gl_dlist_node * node) Line 603 C opengl32.dll!execute_list(gl_context * ctx, unsigned int list) Line 7505 + 0x12 bytes C opengl32.dll!_mesa_CallList(unsigned int list) Line 8923 C opengl32.dll!glCallList(unsigned int list) Line 100 C Any help greatly appreciated. </blockquote> </div></div> The win32/gdi driver hasn't been maintained in quite a while.
