Steps to a working didj build environment using Ubuntu 9.1 (Karmic Koala)
Add the following line your "/etc/apt/sources.list":
deb http://scratchbox.org/debian/ stable main
Install Scratchbox:
sudo apt-get update sudo apt-get install scratchbox-core scratchbox-devkit-cputransp scratchbox-devkit-debian scratchbox-libs scratchbox-toolchain-arm-gcc4.1-uclibc20061004
Add these settings to /etc/sysctl.conf
vm.vdso_enabled = 0 vm.mmap_min_addr = 4096
Run:
sudo sysctl -p
Add yourself to the "scratchbox" user group:
sudo /scratchbox/sbin/sbox_adduser "$USER"
Make a symbolic link to avoid sudo errors:
sudo ln -s /scratchbox/tools/bin/fakeroot /scratchbox/tools/bin/sudo
At this point you will need to log out of and then back in to your computer and re-open terminal.
Enter "scratchbox" into a terminal to start the sandbox environment:
- Next, enter "sb-menu" to bring up the Scratchbox configuration menu.
- Then you'll want to select "Setup".
- Select "<NEW>" for a new target, then enter "didj" as your target name.
- Choose "arm-gcc4.1-uclibc20061004" as your compiler.
- Then, browse down to select the "cputransp" development kit. Then select "DONE".
- Next, select "qemu-arm-cvs" for your CPU-transparency method.
- Then, choose "NO" for extracting a rootstrap to the target.
- Select "YES" to install files on the target. Choose any extra packages to install, and then select "OK".
- Finally, choose "YES" to select the target you just created.
Run:
wget http://medialib.leapfrog.com/didj_opensource_code/Didj-Linux-4222-20090422-1236.tar.gz
And decompress it:
tar -xzf Didj-Linux-4222-20090422-1236.tar.gz
Run:
nano .bashrc
And put in this text:
export PROJECT_PATH=~/Didj-Linux-4222-20090422-1236 export TARGET_MACH=LF_LF1000 export CROSS_COMPILE=sbox-arm-linux-uclibc export ROOTFS_PATH=~/didj-rootfs export RELEASE_PATH=~/release export TFTP_PATH=~/tftp
Exit scratchbox
Run:
sudo cp /scratchbox/users/$USER/home/$USER/Didj-Linux-4222-20090422-1236/host_tools/mkimage /scratchbox/compilers/bin/ sudo mv /scratchbox/users/$USER/home/$USER/Didj-Linux-4222-20090422-1236/host_tools/mkimage /scratchbox/users/$USER/home/$USER/Didj-Linux-4222-20090422-1236/host_tools/mkimage.disable
Now go go back into scratchbox and run:
mkdir didj-rootfs mkdir release mkdir tftp ./Didj-Linux-4222-20090422-1236/scripts/make_rootfs.sh
If you want to change kernel options, make sure you are not in scratchbox and run these commands:
sudo apt-get install libncurses5-dev cd /scratchbox/users/$USER/home/$USER/Didj-Linux-4222-20090422-1236/linux-2.6.20-lf1000 make menuconfig
