[Mesa-dev] [PATCH 12/26] targets/vdpau-nouveau: convert to static/shared pipe-drivers
Emil Velikov
emil.l.velikov at gmail.com
Thu Jun 12 12:56:32 PDT 2014
Create a single library (for the vdpau api) thus reducing
the overall size of mesa. Current commit converts
vdpau-nouveau, with upcomming commits handling the rest.
The library can be built with the relevant pipe-drivers
statically linked in, or loaded as shared modules.
Currently we default to static.
Add SPLIT_TARGETS to guard the other VL targets.
Note: symlink handling is rather ugly and will need an
update to work with BSD and other non-linux platforms.
v2: Split the conversion into per-target basis.
