• Install the package. It will take some time, and ask a few questions during the process:
  • "An update for this bootstrap contents may be available now... would you like to update now?" Choose "yes"
  • "Would you like to install the X-Server now?" If you do not have Xming installed and want to, install it. It's not needed for rockbox builds, and probably won't be needed for simulator builds once that's supported (we'll probably build native Win32 SDL simulators).
• Using Windows explorer, go to <C:\Documents and Settings>\All Users\<Start menu>\<Programs>\Windows Services for UNIX (replace parts in <> with the correct values for your language version of Windows), and duplicate the "Korn Shell" shortcut
• Rename the duplicate shortcut to "Bourne Again Shell", and edit the following properties:
  • Target: C:\WINDOWS\system32\posix.exe /u /c /usr/local/bin/bash -l
  • Comment: Runs the Interix Bource again shell

• Start bash
• Check whether perl is properly installed: which perl
  If perl isn't found (happened reproducably during my tests) the bundle installer goofed, and you need to fix it: pkg_update -Lr perl
• Make a symlink so that perl is found where many scripts expect it: ln -s /usr/local/bin/perl /usr/bin/perl

SFU 3.5 only: SFU 3.5 comes without inttypes.h and stdint.h, however, these are needed for rockbox tools and sims and all kinds of other stuff. Download inttypes-sfu3.5.zip, extract it and put both .h files into /usr/include.

Edit /etc/profile.lcl You'll probably want the following settings:

# Set a home directory within the SFU path if available
if [ -d /home/$USERNAME ]; then
    export HOME="/home/$USERNAME"
    cd $HOME
fi

# Shell dependent settings
case "`echo "_$0" | /usr/bin/tr '[:upper:]' '[:lower:]' | /usr/bin/sed -e 's/^_//'`" in
bash     | -bash     | */bash )
    # Set a default prompt of: user@host and current_directory
    export PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$ '
    ;;
* )
    # Sorry, this shell has no defaults in /etc/profile.lcl
    #  feel free to add your own.
    export PS1='$ '
    ;;
esac

Using a directory without spaces as the home directory for users will avoid a lot of trouble. You need to create the directories and set the proper permissions. Note that the username must be capitalized the exact same way as it is used for logging into windows.

Step 5: Build an up-to-date GNU make

The following steps need to be performed as a local administrator!

The version of GNU make shipped with the Interopsystems developer bundle is outdated. We want GNU make 3.81 for optimum build performance.

Check the installed version: pkg_info gmake
If it shows GNU make version 3.81, skip the rest of step 5

Uninstall the bundled version of GNU make: pkg_delete gmake-3.80.1-bin

Download the GNU make sources

Unpack the source and cd into the directory
./configure --program-prefix=g
make
make install

Step 6: Perform initial SVN checkout and build the crosscompilers

Start bash, and check out rockbox SVN. Then cd into tools/. Since Interix already has a lot of stuff in /usr/local, and also puts its own GCC unter /opt, it is recommended to put the crosscompilers under /opt as well. Edit rockboxdev.sh accordingly.

• Become Administrator
• The developer bundle adds a few include paths to CPPFLAGS which would confuse the crosscompiler build. Deactivate them temporarily: export CPPFLAGS=-D_ALL_SOURCE
• Build the crosscompilers as normal: ./rockboxdev.sh
• exit from the Administrator shell

Step 7: Adjust the user environment

Edit ~/.profile, and add the path(s) to the crosscompiler(s) you've just built.

In order to be able to use non-ASCII characters in bash (e.g. German umlauts), edit ~/.inputrc and add the follwing lines:

set meta-flag on
set convert-meta off
set input-meta on
set output-meta on

Close bash and restart it.

Done. happy hacking :-)
