[Mesa-dev] The long way to a faster build with shared libs and some fixes ...

Wed Sep 11 23:41:10 PDT 2013

I completely agree.

Building everything shared might speed up the build process a little bit 
and save some space, but for the cost of having to handle allot of 
rather small shared libraries where which each clashing the symbol space 
of any application using these drivers with a bunch of unnecessary symbols.

Building everything as one big blob sounds like the better idea.

Christian.
