We were mis-computing the size of the user-space vertex buffer in some circumstances. This led to a failed assertion at u_inlines.h:222 when using the VMware svga driver. For example, if we had arrays such as: array[0]: element_offset = 12, stride = 24 array[1]: element_offset = 0, stride = 24 We'd mistakenly compute 'bytes' to be 12 bytes too small. I've reorganized the function too. By time it's called, we know that we've got interleaved arrays either all in one VBO or all in user memory and the stride is equal for all arrays. Move the code that lived inside the attr==0 test after the loop. In the loop we compute the true vertex size. That size factors into the pipe->redefine_user_buffer() call later. Using the vertex size instead of array[0]'s element_offset fixes the failed assertion. Reviewed-by: José Fonseca <jfonseca@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.
