I'm running OS X Leopard on an intel Macbook.

I was able to muddle through getting 1.34.1 built universal.

In order to build Boost universal, I followed the instructions

I stumbled upon here:

I modified it slightly to build with the OS 10.5 sdk. I have appended

my user-config.jam file.

I am interested in using ASIO, which depends upon

Boost.System. Boost.System is not included in 1.34.1,

but it is included in the ASIO download. I can build and

have built system according to the instructions in the ASIO

README, but these instructions result in an i386 only build.

Any ideas how I can build and install Boost.System universal

with 1.34.1? Or, is there a better way altogether?

Thanks in advance.
