Commit4ed23fd590introduced some calls to _eglError inappropriately passing it EGL_BAD_NATIVE_WINDOW. This was actually harmless in two of the cases as _eglError gets called later on with a more appropriate error code but (just to be safe) switch these to _eglLog calls instead. The final case is a little trickier as it actually needs to set an error of which the following are available (according to the EGL spec): EGL_BAD_MATCH, EGL_BAD_CONFIG, EGL_BAD_NATIVE_(PIXMAP|WINDOW) and EGL_BAD_ALLOC. Of these, EGL_BAD_ALLOC seems to be the most appropriate given that failure can occur either as a result of xcb_get_setup failing due to an earlier error on the connection (where the most commonly occurring error code is XCB_CONN_CLOSED_MEM_INSUFFICIENT) or as a result of the xcb_screen_iterator_t 'rem' field being 0. In addition to this, commitaf2aea40d2unconditionally set the error to EGL_BAD_NATIVE_WINDOW when creating a window or pixmap surface with a NULL native handle. Change this to correctly set the error based on surface type. v2: Updated patch description (Emil Velikov) Return EGL_BAD_NATIVE_PIXMAP when eglCreatePixmapSurface is called with a NULL native pixmap handle Signed-off-by: Frank Binns <frank.binns@imgtec.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com>
File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run 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. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons 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.
