Hi,

Earlier today, while doing some coursework which has to be in on monday, I was just finishing off some code to present.

Except, something happened... thats not the point, but the point now is, whenever I compile anything using the command:

gcc -o -pedantic anyfile anyfile.c

I get some huge error, it looks like this:

cd ~/networks/
gcc -o pedantic shell shellbuiltin.c

Compilation exited abnormally with code 1 at Fri Mar 26 19:20:07

Does anyone know what this signifies? Has my compiler decided to just die or something? It just happened suddenly, I have no idea what this means.

Thanks
