Can't compile source code in RPi Zero image

Hello everyone!

I’m trying to build some kind of GameBoy console with Raspberry Pi. But to do that I need to use the GPIO pins as buttons,to do so I’m using the Adafruit Retrogame software.

But I’m having two problems:

1- I can’t remount the root partition to Read and Write with the command:

#mount -o remount,rw / 

Maybe this command doesn’t work because I can’t get access to the /etc/fstab file.

2- I can’t compile anything with gcc because the compiler does not exists inside the /bin folder.

How can I compile my source and how can I make the file system writable?

Can someone help me ?

It seems I can’t properly delete my post, so I’ll link to hunterk’s response in your other thread. It says everything I wanted to say.
