This patch fixes segfaults observed when enabling the post processing features. When the format is not supported, or a texture cannot be created, the code must gracefully handle failure and report the error to the calling code for proper failure handling. To accomplish this the following changes were made to the filters.h prototypes: - bool return for pp_init_func - Added pp_free_func for filter specific resource destruction Fixes segfaults from backtraces: * util_destroy_blit pp_free * u_transfer_inline_write_vtbl pp_jimenezmlaa_init_run pp_init This patch also uses tgsi_alloc_tokens to allocate temporary tokens in pp_tgsi_to_state, instead of allocating the array on the stack. This fixes the following stack corruption segfault in pp_run.c: * _int_free aaline_delete_fs_state pp_free Bug Number: 1021843 Reviewed-by: Brian Paul <brianp@vmware.com> |

File: docs/README.WIN32 Last updated: 23 April 2011 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons osmesa mesagdi to build classic mesa Windows GDI drivers; or scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
