Re: ddd/gdb

[Arnaud Desitter]

Hi,

If you want to debug some code compiled by gcc/g++/g77,
use "ddd --gdb".
If you want to debug some code compiled by the HP compilers,
then you need to install the HP debugger (wdb) and use
"ddd --wdb".
Indecently, I thought that HP f77 was discontinued. I suppose
it is an alias for f90.

Regards,
