I'm guessing that card_extensions in r300_context.c is wrong. There are a few extensions listed there that have NULL for their functions field. For example, the entry for GL_ARB_vertex_program should clearly be GL_ARB_vertex_program_functions instead of NULL. If there's an _functions structure in src/mesa/drivers/dri/common/extension_helper.h, it needs to be referenced in the dri_extension structure array. That's how driInitExtensions and driInitSingleExtension know what functions need to be added to the dispatch table. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFC9CdRX1gOwKyEAw8RAk3SAKCgY4I1K9r+UFmcTIQI+KpWUmIrNQCfZyHf pPCdVVU+ZndfhYlmRGUNjWY= =C3xR -----END PGP SIGNATURE----- ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
