I am trying to understand the s3tc init code as nv50 gallium has a problem with that. It looks like some drivers (r300g and llvmpipe) actually inits s3tc in two places : ./src/mesa/main/texcompress_s3tc.c _mesa_init_texture_s3tc() ./src/gallium/auxiliary/util/u_format_s3tc.c util_format_s3tc_init() Here is an extract of the backtrace calls while loading fgfs on llvmpipe : driCreateScreen -> llvmpipe_create_screen -> util_format_s3tc_init driCreateContext -> st_create_context -> _mesa_create_context_for_api -> init_attrib_groups -> _mesa_init_textur...

flightgear now dies with : Mesa warning: external dxt library not available: texstore_rgba_dxt3 util/u_format_s3tc.c:66:util_format_dxt3_rgba_fetch_stub: Assertion `0' failed. I don't really understand what these stubs are about, they were introduced by following commit : commit d96e87c3c513f8ed350ae24425edb74b6d6fcc13 Author: Jos?
