[Ubuntu 11.10] No more able to compile

[odexios]

Hello everyone!

I upgraded a couple of hours ago my old, trusted Ubuntu 10.10 to the latest version.

If Unity wasn't enough, apparentely I'm not able anymore to compile crawl; when I try, I get these messages:

  Code:

giovanni@giovanni-1015P:~/Downloads/crawl/stone_soup-0.9.2/source$ make
    CXX arena.o
<command-line>:0:0: warning: "_FORTIFY_SOURCE" redefined [enabled by default]
<built-in>:0:0: note: this is the location of the previous definition
    CXX artefact.o
<command-line>:0:0: warning: "_FORTIFY_SOURCE" redefined [enabled by default]
<built-in>:0:0: note: this is the location of the previous definition


And so on, for every file being compiled.

Apart from the warnings I didn't get any error, but when I tried to launch ./crawl, nothing happened.

I tried to recompile everything, and nothing changed.

Am I the only one who got this kind of behaviour? Any idea?

EDIT: Ok, the third try was succesfull. Still, I got the same warnings (the _FORTIFY_SOURCE ones). Is there anyone who can tell me what they are about?
