You probably can't build from libsa itself. If you make in biosboot, it sets up some cunning arguments to point cpp at the right directories. > > > If anyone is interested, the hacked sources are in > > freefall:~dfr/netbsdboot.diff.gz.

I think it *might* be possible to use libz from /usr/src/lib but it really needs to be rebuilt in a cunning way (I think) so that it can run in the standalone environment. I'll think about it. I don't think the i386 bootloader will have much resemblance to the alpha bootloader so that part should stay with the kernel since it has such an intimate relationship with it. > > ... and just for dessert, I take it you were only building the biosboot > loader? Of course! I also built installboot (which was pretty easy). I don't expect to have much trouble with dosboot and netboot but I can't test them. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
