In the early days of Xorg and Mesa we had multiple providers of the GLAPI. All of those were the ones responsible for dlopening the DRI module. Hence it was perfectly fine, and actually expected, for the DRI modules to have unresolved symbols. Since then we've moved the API to a separate shared library and no other libraries provide the symbols. Here comes the picky part: It's possible that one uses old Xorg (where libglx.so provides the GLAPI) and new Mesa (with DRI modules linking against libglapi.so). That should still work, since the the libglx.so symbols will take precedence over the libglapi.so ones. I've verified this while running 1.14 series Xorg alongside this (and next) patch. It may seem a bit fragile, but that's of reasonably OK since all of the affected Xorg versions have been EOL for years. The final one being the 1.14 series, which saw its final bug fix release 1.14.7 in June 2014. To ensure that the binaries do not have unresolved symbols add -no-undefined and $(LD_NO_UNDEFINED), just like we do everywhere else throughout mesa.

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 https://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.
