Title: Automatic RB build from SVN. Script in BASH
Post by: siwy on February 12, 2008, 11:57:43 AM: I have written a small script in BASH (requires sed but everyone has it) which builds rockbox automaticly from subversion.

Some instructions:
copy the text below (beginning from #!/bin/bash), paste it into notepad and (as root) save as /usr/bin/rb. make it executable by 'chmod +x /usr/bin/rb'

you also have to change some things. first of all edit MOUNT_DIR, SVN_DIR and BUILD_DIR. second of all run 'svn up rockbox' manually, look at the last line and notice how many non-numeric characters there are (counting from the end to the beginning) . eg. my last line looks like follows: "W wersji 16290." So there is only 1 non-numeric character from the end which is "." Understood? Now, you have to change value -6 in this line: "SVN=${SVN: -6: 5}" If you have 0 non-numeric charcter it has to be -5, if you have 1 (like me) it has to be -6, Â if you have 2 it has to be -7 and so on. That's all. Enjoy.

It works only if you have all the development enviroment set. I mean you have RB source code, build folder and cross-compilers.

This code is published under wtfpl-2 license.

#!/bin/bash

#It works only if you have been set development enviroment up earlier

#Configuration of the enviroment
MOUNT_DIR="/media/IAUDIO"
SVN_DIR="/home/mati/rockbox"
BUILD_DIR="/home/mati/rockbox/build"

#Checks if there is any RockBox on the player
if [ ! -e $MOUNT_DIR/.rockbox/rockbox-info.txt ]
   then
      echo "Please mount your DAP on $MOUNT_DIR."
      exit 1
fi

#Checks version of RockBox in SVN
cd $SVN_DIR
SVN=$( svn up | sed -n '$p' )
SVN=${SVN: -6: 5}   #These parameters depend on language of Subversion
                  #you are using

FILE=$( grep 'Version: r' $MOUNT_DIR/.rockbox/rockbox-info.txt )
FILE=${FILE: 10: 5}   #These parameters depend on language of Subversion
                     #you are using

if [ "$SVN" = "$FILE" ]
   then
      echo 'Your Rockbox is up-to-date.'
      exit 0
   else
      cd $BUILD_DIR
      echo -e "31\nN\n" | ../tools/configure #Set type of your DAP here
      make -j 3 #Set it properly to boost performance
      make tar
      tar xvf ./rockbox.tar -C $MOUNT_DIR
      echo -e "\nSuccessfully updated from $FILE to $SVN."
      exit 0
fi

echo 'Unknown error!'
exit 1

However - it doesn't belong in the forums - please move it into the wiki where it will be findable forever :)

Post by: NicolasP on February 12, 2008, 06:18:52 PM: Quite a nice script, yes. Maybe this could even go in the tools/ directory in SVN!

Post by: siwy on March 14, 2008, 10:05:00 AM: UPDATE
finally the script above is correct and works properly, makes no problems and is more verbose.
You don't need to test it, just use it!
