I am attempting to compile a program with g77 and I keep getting the following error:

/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

I saw on another forum that this is related to libgcc, when looking for libgcc I get

>find /usr/ -name libgcc*

I am running an extensive code that I requires g77 to compile. (yes I could probably debug for gfortran but it took me months just to get it working so I really really don't want to). I have tried http://astrokode.wordpress.com/2012/10/31/installing-g77-compiler

but I get this error when I try to install:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package g77 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'g77' has no installation candidate

I have seen on forums that people are installing the g77 for Ubuntu 8.04, but I am fairly new to Ubuntu and unclear of exactly how to do this.

I recently re-installed Ubuntu 12.04 on my Dell Machine.

After re-installation, I had problems installing wireless driver under Additional Drivers.

I tried a lot of different things, ultimately removing bcmwl-kernel-source and installing firmware-b43-lpphy-installer and b43-fwcutter.

Initially, nothing happened, but then out of the blue, I checked the internet tab and could see my network. I was able to connect and use wireless all day yesterday, but now it isn't working again.

Under internet icon in upper right hand corner, computer says wireless is enabled, but wireless networks are disconnected.

Below I've included some info.
