[Mesa-dev] [PATCH] Haiku: Add Gallium winsys and target code
Alexander von Gluck IV
kallisti5 at unixzen.com
Tue May 21 14:10:32 PDT 2013
* We generate a static library for Haiku
Gallium targets as our port system combines
the compiled rendering code into a modular
ar for each module (for example, our port
system combines llvm libsoftpipe.a libllvmpipe.a
into a single ar for the Haiku build system.
I'd like the Gallium hgl target scons build
system to do this some day, however how is
beyond me at the moment. This is a first step.
