I'm trying install ssh in my firewall linux box, when system run ./confugre 
in ssh-2.4.0 directrory the next error message is displayed:
....
checking whether the C compilier (gcc -g) works...no
configure error: installation or configuration problem: C compiler cannot 
create executalbles.

Where is the mistake?

Thanks
