Volodya,

I thought I solved this problem on my own, but my solution differs  
from yours, so I thought I'd ask what you think.  In my user- 
config.jam file, I added the following:

using darwin
    :   4.0
    :   # no command
    :   <compileflags>"-arch x86_64 -arch i386 -arch ppc64 -arch ppc"
        <linkflags>"-arch x86_64 -arch i386 -arch ppc64 -arch ppc"
    ;

This seems to work (as evidenced by running otool -f on the resulting  
binaries), but it doesn't seem to have an effect on building the boost  
libraries themselves.

The architecture=combined approach doesn't specify which architectures  
should be included in the fat binary.  Should I specify both the flags  
above and architecture=combined?

Thanks,

Ian

Hi Jonathan,

I don't know what build-framework.sh is, and how it works. For building
fat binary you need to add architecture=combined to bjam command line --
you probably can modify your script to pass that.
