Bash script for compile programs to ARM CORTEX M4F with StellarisWare

Target: LM4F120 Series of ARM Cortex-M4 (Texas Instruments)
OS Platform tested at the moment: Linux Ubuntu 13.04

Hi, in my last post i presented a script to install all tools to start developing in ARM on linux. Now i would like to present a script compiler that helped me when the makefiles didn't work well. I did this to copy the files required to compile from the stellaris folder and after compile all .c files from the target folder pointed by the user. The script asks for the source folder of your project (ex. ~/test_arm), the stellarisware folder library and the name of the main file (test.c). If all occur ok, you will see threes "Complete!", if some "Failed!" appear you will see a file named log_compiler.txt created. In this log_compiler.txt you can see what happened with the compilation. If you have some problem to use, just leave a comment and a i will be greatful to answer you.

Step 1. Create the file:

Just open any text editor, like gedit and paste the script below, after save the file with "name.sh"
SCRIPT:

#!/bin/bash

#to run just type in terminal sudo chmod  +x compilator.sh, add your password and execute (./compilator.sh)

  srcDir=$HOME$srcDir

echo $srcDir
read -e -p "Please type the directory folder of the stellaris library:" srcLib 
if [[ $srcLib == *~* ]]
then
  srcLib=$(sed -e 's/~//' <<<$srcLib)
  srcLib=$HOME$srcLib

cd "$srcDir"

echo $srcLib
read -e -p "Please type the name of the main file project(*.c):" srcMainFile

echo "LOG - USER:$USER" &>  log_compiler.txt

echo -e "\n\e[34m Compilation Finished!, for details see log_compiler.txt\e[97m"

exit 0

Step 2. Change the permission to execute:

In this step you just need to change the permission to execute the file into your system and for this open the terminal to put the command below:

sudo chmod +u name.sh

Step 3. Executing:

Before to execute i almost lost to advice, but you need to download the Stellaris Ware(SW-EK-LM4F120XL) from this link http://www.ti.com/tool/sw-ek-lm4f120xl and put them into your ~/Downloads directory. And for finish, to execute the script just call them with "./name.sh" like below:

./name.sh

Tks All.
