Download, compile, and install the Broadcom BCM 2835 library for the Raspberry Pi

gistfile1.sh

cd; 
// wget http://www.open.com.au/mikem/bcm2835/bcm2835-1.5.tar.gz; // My Pi can't figure out this URL
wget http://67.192.60.197/mikem/bcm2835/bcm2835-1.5.tar.gz
tar xvfz bcm2835-1.5.tar.gz; 
cd bcm2835-1.5; 
./configure; 
make; 
sudo make install

latest version (2016-01-16)
bcm2835-1.49.tar.gz

wget http://www.open.com.au/mikem/bcm2835/bcm2835-1.49.tar.gz
tar xvfz bcm2835-1.49.tar.gz; 
cd bcm2835-1.49;

// Thanks @annem, I think the url and version formatting have changed again in the meantime. This worked for me:
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.50.tar.gz;
tar xvfz bcm2835-1.50.tar.gz;
cd bcm2835-1.50;
./configure;
make;
sudo make install

This worked for me: wget http://www.open.com.au/mikem/bcm2835/bcm2835-1.55.tar.gz

I cooked up this one so I do not have to think about version numbers:

sudo apt-get install html-xml-utils
mkdir -p bcm2835 && (wget -qO - `curl -sL http://www.airspayce.com/mikem/bcm2835 | hxnormalize -x -e | hxselect -s '\n' -c "div.textblock>p:nth-child(4)>a:nth-child(1)"` | tar xz --strip-components=1 -C bcm2835 )
cd bcm2835
./configure
make
sudo make install

i have using rasbperry pi 3 cross compiler in linux but how to add my processor library (bcm2837.h)
