-=== Compile and Run ===
+From a bare ubuntu 12.04 LTS you need to add the following packages:
+<code>
+sudo apt-get install build-essential m4 texinfo libncurses5-dev bzip2
+</code>
+Copy the script "build_mips.sh" from below to your home directory. Open a terminal window in ubuntu by starting dash and typing terminal.
+The click terminal which opens the terminal. To change the current directory to your home directory type
+<code>
+cd
+</code>
+To see the full path of the current directory:
+<code>
+pwd
+</code>
+List the directory contents with
+<code>
+ls -la
+</code>
+Change the file attributes of "build_mips.sh" to executable with
+<code>
+chmod a+x build_mips.sh
+</code>
+Look into the bash script with
+<code>
+less build_mips.sh
+</code>
+Extend the search path by appending "export PATH=$HOME/site/bin:$PATH" to your .profile file
+Log out and login again to make the PATH variable active. Check your PATH variable with
+<code>
+echo $PATH
+</code>
+You should see the <..>/site/bin as the first entry.
+Run the build script with
+<code>
+./build_mips.sh
+</code>
+Here is the shell script for building the cross compiler chain. Handmade
+stuff so you need to adapt. The script will build to a place in your home
+directory. So first add this place to your PATH variable.
+<code bash build_mips.sh>
+#!/bin/bash -ev

+===== Compile and Run an example =====
+Here is an example mini c code to test the compiler.
+<code c hello.c>
+/* Hello world */
+#include <stdio.h>
+int myfunc(int a, int b){
+  int k;
+  k = a + b;
+  k += 7;
+  k *= 6;
+  return k;
+}
+int main(){
+  int i,j,m;
+  j = 3;
+  m = 2;
+  for(i=0;i<5;i++){
+    m += myfunc(i,j);
+    printf("m is %d\n",m);
+  }
+  return 0;
+}
+</code>
 Compile to Assembler for viewing
-mipsel-none-elf-gcc -S fir.c
+<code>
+mipsel-none-elf-gcc -S hello.c
+</code>
-The output is fir.s which is the assembler code.
+The output assembler code is in hello.s.
 Compile and link ready for simulation with instruction set simulator
-mipsel-none-elf-gcc -o fir -Tidt.ld fir.c
+<code>
+mipsel-none-elf-gcc -o hello -Tidt.ld hello.c
+</code>
 Run the code
-mipsel-none-elf-run fir
+<code>
+mipsel-none-elf-run hello
+</code>
 === Analyze ===
-Produce an annoted source code
+Produce an annoted source code showing how often lines are executed.
-gcc -fprofile-arcs -ftest-coverage -o fir fir.c
+<code>
+gcc -fprofile-arcs -ftest-coverage -o hello hello.c
+./hello
+gcov hello.c
+</code>
-./fir
+This produces the file hello.c.gcov showing the annotated source file.
-gcov fir.c
+=== Tracing in instruction set simulator ===
 Run with instruction tracing in the simulator
-mipsel-none-elf-run --trace-insn=on --trace-file trace fir
+<code>
+mipsel-none-elf-gcc -Tidt.ld -o hello hello.c
+mipsel-none-elf-run --trace-insn=on --trace-file trace hello
+</code>
+===== Test the compiler =====
+<code>
+sudo apt-get install dejagnu
+</code>
+<code>
+cd
+cd mips/build/gcc-stage2
+make check-gcc RUNTESTFLAGS=--target_board=mips-sim
+</code>
+===== Install git and download a simple project  =====
+Install git and download a simple project
+<code>
+sudo apt-get install git
+cd
+mkdir projects
+cd projects
+git clone https://git.etech.fh-augsburg.de/friedrich.beckmann/myfirst.git
+</code>
+Now you have the simple project "myfirst" in your directory.
+=== Try the MIPS Cross Compiler ===
+Change to the src directory and compile the code with the cross compiler.
+<code>
+cd myfirst
+cd src
+mipsel-none-elf-gcc -S hello.c
+less hello.s
+</code>
+Now you have the compiled assembler code "hello.s". To compile to binary do:
+<code>
+mipsel-none-elf-gcc -o hello -Tidt.ld hello.c
+</code>
+Now you have the binary "hello". You can run the binary in the instruction set simulator with
+<code>
+mipsel-none-elf-run hello
+</code>
+This will run the binary with the mips instruction set simulator. You should see "Hello World".
