Re: Fw: Can't build gcc 3.3.4 Linux to Sun Cross compiler

["Mark Cuss" <mcuss at cdlsystems dot com>]

Thanks for the help.

Gcc 3.3.3 builds natively on Sun OK (we've been using it for months), it's
just the cross compiler that won't build - sounds like you could be right on
the misconfigured libstdc++.

Sorry - I didn't know that this wasn't the place to post these sorts of
questions...  If I have more questions on building and configuring gcc where
should I ask them?

Thanks!
Mark
