I am trying to build a 64 bit binary from C++ code using 32bit g++ compiler.
I am getting the following errors while building:

It seems I need 64bit libstdc++ available on my build system. Could you please throw some light to solve this.
Q1) Is it ok to build 64 bit binaries using 32 bit g++ compiler on AIX 5.2
Q2) Where should I get 64 bit libstdc++? Will this 64 bit libstdc++ work with 32bit g++ compiler?
