[sldev] ZLib and Boost

[Brad Kittenbrink (Brad Linden)]

Oops, I think you got tripped up by a change we recently made to trunk 
for building our 32 bit viewers on 64 bit machines.  I meant to announce 
this here ahead of time, but it slipped through the cracks.

I think anyone doing standalone builds on 64 bit distributions will get 
the same errors.

There is now a new (as of r2201 i think) optional argument to develop.py 
(and equivalently a new cmake variable) to configure whether you are 
building 32bit or 64bit code, and it defaults to 32bit.

If you want to build a 64bit viewer you probably want to configure using 
something like the following:
./develop.py -m64 --standalone configure

If you want to build a 32bit viewer, you'll need your distro's 32bit 
development libs installed (on debian it's called libc6-dev-i386 and I 
additionally needed libglu1-mesa-dev) and you'll either need to do a 
non-standalone build, or build 32bit versions of all third party libs.

If you're not using develop.py and running cmake by hand you'll need to 
pass -DWORD_SIZE=64 as an extra argument to cmake to override the default.

apologies for the surprise,
-Brad
