gcc linking problem - badly installed?


Hi,

I am new to this list, so please excuse me and
give me a hint if this topic was treated here
before.

I tried some simple C and F77 "hello world"
programmes to get compiled and linked by "gcc"
and "gcc -c" + "ld".  The .o was created by
"gcc -c" without error message, but both direct
executable creation with "gcc" and linking the
.o by "ld" failed, giving different error
messages.  The .log I appenden at the bottom of
the email.  Does anyone have an idea what is
going wrong?

Thanks in advance

Enno.
