 == Boost ==
 
+Boost unfortunately uses its own unique build system, and getting the options right isn't nearly as easy.
+
+This blob of bjam options wil build with optimization and debugging on.

+{{{

 == PostgreSQL ==
 
+Qt has a database layer that can connect to several databases such as sqlite3, postres, and mysql. Since I h ad a non-universal copy of postgresql installed, Qt detected it and tried to build with it, and then failed with it tried to link the single archtecture library against a fat binary. Because I was stubborn, I upgraded postgres unstead of telling Qt to not include Postgres.
 
+In several places the Postgres make files attempt to construct an .o file out of several other .o files using ld. On OS X ld can only handle single architectures, and developers are supposed to switch to libtool. I didn't want to modify the postgres build system so I wrote another small python script source:makelib/uld that wrapps ld with a little bit of glue to handle the multiple architectures.
+
+With that bit of assitance the following should work.
+
+{{{
+export CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386 
+export LD="<path to uld>/uld -arch i386 -arch ppc"
+./configure
+make
+}}}
+
+One can't add -arch options to both CFLAGS and LDFLAGS as there are a number of places where the Postgres build system passes both $CFLAGS and $LDFLAGS to gcc which generates a duplicate -arch error message. (In the process breaking configure).
