[Mesa-dev] [PATCH 0/6] Overhaul of Gallium configure options

[Jose Fonseca]

* --enable-debug  => build=debug (there's also, "profile", "checked", and "release")

* --with-xxx --disable-xxx  => just say list target you want, and scons will build that target, and all depencies, and nothing more. For example

   scons dri-r600g

It would be nice to have a list of all targets, but I don't know.  Another approach is to specify the directory:

   scons src/gallium/targets/dri-swrast/

The rest, --prefix=/usr --enable-glx-tls --enable-texture-float, has no equivalent yet: there's no install support, and libGL is not being built yet either. Hopefully soon.

Jose
