Apologies in advance if I missed the docs describing how to accomplish
this. I *REALLY* tried to find them on my own.

=20

I'd like to build the boost libraries for multiple gcc [cross]
compilers. I think the first step would be to modify a user-config.jam
to include something like the following:

=20

using gcc : 3.4 ;

using gcc : 3.? : /path/one/arm-g++ : <other stuff> ;

using gcc : 3.? : /path/two/ppc-g++ : <other stuff> ;

=20

But then I'm stuck. (1) How do I invoke bjam to compile all three
libraries - the default that's in the path (linux x86 in this case),
then the arm-g++, then the ppc-g++? (2) Then there's the question of
having the results show up in three different directory trees; (3) and
finally, how do I differentiate version numbers when the version number
is the same for all three compilers?

=20

Any explanation or reference to the appropriate place in the
documentation would be *GREATLY* appreciated.

=20

PS: I thought I saw that an "alias" could be added to each version by
including it after the version followed by a space (i.e.,=20

using gcc : 3.? gcc-arm : /path/one/arm-g++ : <other stuff> ;) Now I
can't find this mentioned. Does it work this way - or was I smoking
crayons?

=20

Sincere thanks in advance,

Dick Bridges
