552,Building universal binary on MacOSX,shaishasag,René Rivera,"{{{
I'm using boost libraries on Windows (VC++) And MacOSX
(gcc).

Currently on MacOSX boost compiles for PPC processor.
As Apple is moving to Intel processors, I would like to
be able to compile boost, on the Mac for both PPC and
Intel.

Apple created the universal binary format, where you
compile and link the code twice, the only difference in
the compilation is a single option: -arch ppc or -arch
i386.

Later a tool called CreateUniversalBinary is called
upon the linked codes. CreateUniversalBinary merges the
two binaries into one. During runtime, the operating
system loads the code and chooses which part to run,
according to the local processor.

I tried looking into the jamfiles but was overwhelmed
by the complexity.

What would be the best method to achieve universal
binary on MacOSX?
