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

["Basavaraj Talwar" <bt@xxxxxxxxxxxxxxxxx>]

I have only one gcc (v4.3.0) on my machine. the outputs are shown here.

$ strings /lib/libgcc_s.so.1 | grep GCC
GCC_3.0
GCC_3.3
GCC_3.3.1
GCC_3.4
GCC_3.4.2
GCC_4.0.0
GCC_4.2.0
GCC_4.3.0

$ strings /usr/lib/libstdc++.so.6 | grep GCC
GCC_4.2.0
GCC_3.3
GCC_3.0

I will use an older gcc (i'll try 3.4.6 as in your example) and try
compiling again.

Thank you very much.

BT.
