Linker problem

Linker problem

[Flavio Pereira]

Hi All

Im trying to cross compile some c++ code for the 8260 chip. However when
the linker executes it return the following error:

undefined reference to `__throw'

Can anyone please give some advice on how to tackle this problem? What
does this mean? Does it have anything to do with c++ libraries??? Im
using the cross compile environment set up by the ELDK Kit from DENX.

Regards
Flavio Pereira

Can you show us your example  code,  and  the  commands  you  use  to
compile and link it?

Does it work with the native (x86) C++ compiler?

Best regards,

Make it right before you make it faster.

You must be doing something wrong here. The g++ as included with  our
ELDK  does  not reference any "-lstdg++". Can you please show us some
(simple) exaqmple source and the exact command line you  use,  so  we
can test if there is really a problem, or just a usage error?
