Re: [Gems-users] Fwd: ruby/opal "version 'GCC_4.2.0' not found" error

["Basavaraj Talwar" <bt@xxxxxxxxxxxxxxxxx>]

Sir,

I got past the previous error.
I used binaries (g++) and libraries (libstdc++.so.6, libgcc_s.so etc)
from the newly installed gcc.3.4.6 directory to compile ruby and opal.
Thank you very much.

BT.
