64bit compiling and linking on AIX 5.3

["Michele Mazza" <michele.mazza@xxxxxxxxxxx>]

Hello,

I need to compile and link my library as a 64bit application on AIX 5.3.

To run my application using libstdc++ library, do I need to compile and use a 64bit version of gcc?
Is this the only way?

Thanks for your help.

Best regards, Michele Mazza
