Pissing about with Ubunu now, my linux is very limited so more learning...

Trying to install virtualbox Guest Additions so I can share the host folders, had to follow this:
https://askubuntu.com/questions/1035...lation-problem

Basically:
sudo apt-get update
sudo apt-get install build-essential gcc make perl dkms
reboot
eject CD
Use Devices menu install Guest additions and follow prompts.

Now I have the Fastboot code on my linux guest...

Trying to follow this to compile it:

failing:

~/Documents/Fastboot-Kindle-master$ gcc -o kfastboot fastboot.c
fastboot.c: In function ‘main’:

collect2: error: ld returned 1 exit status

so I tried the "linuxtool.c" instead, also error messages:

~/Documents/Fastboot-Kindle-master$ gcc -o kfastboot util_linux.c
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start':

collect2: error: ld returned 1 exit status

not really sure what I'm doing!
