Re: 32/64-bit Library Sharing and Placement

[Brian McGrew <bdmcgrew@xxxxxxxxxxx>]

I'm rebuilding much of the gnu toolchain for some development testing I'm working.  GMP, MPC, MPFR, PPL, as well as many others.  I need to be able to have both 32 and 64 bit versions of these libraries avilable on the system, in more or less the same path (/toolchain/lib, /toolchain/lib64).  
 
Generically speaking, is there an easy way to build both 32 and 64 bit versions a the same time???  Or, more specifically, what is the best way to get both versions built???
 
CentOS 6.2 on a Dell 1900 with Xeon 5130 CPU's.

After a few more hours of digging, I believe what I'm wanting is multilib???

Is there a way to get a 32 and 64 bit build (multilib?) in one pass?  If not, what is the easiest way to do this?
