MAC WITH DEBIAN VM CROSS COMPILER FOR RPI
ON THE RPI (if you haven't downloaded openFrameworks)
$ cd
$ curl -O http://www.openframeworks.cc/versions/v0.8.4/of_v0.8.4_linuxarmv6l_release.tar.gz
$ mkdir openFrameworks
$ tar vxfz of_v0.8.4_linuxarmv6l_release.tar.gz -C openFrameworks --strip-components 1
$ cd /home/pi/openFrameworks/scripts/linux/debian_armv6l
$ sudo ./install_dependencies.sh
ON THE MAC:
INSTALL VIRTUALBOX
INSTALL DEBIAN 32BIT SQUEEZE
http://gensho.acc.umu.se/cdimage/archive/7.6.0-live/i386/iso-hybrid/debian-live-7.6.0-i386-standard.iso
Use Bridge Mode (allows access to local network without NAT)
No Desktop Needed
ON THE DEBIAN VM:
NOTE:BELOW INSTRUCTIONS USE pi AS DEBIAN USER
ADD USER TO ROOT GROUP SO CAN USE APT-GET
$ su
$ visudo
# User privilege specification
root ALL=(ALL:ALL) ALL
pi ALL=(ALL:ALL) ALL
$ apt-get install debian-keyring debian-archive-keyring
# apt-key update
Virtualbox will try and boot into PAE mode by default which crashes
$ sudo nano /etc/default/grub
GRUB_DEFAULT=2
$ sudo update-grub
STOP APT FROM LOOKING AT CD FOR UPDATES
$ sudo nano /etc/apt/sources.list
comment out using # or delete line
# deb cdrom:[Debian GNU/Linux 7 _Wheezy_ - Official Snapshot i386 LIVE/INSTALL Binary 20140723-18:00]/ wheezy main
$ sudo apt-get update
MOUNT PI ON DEBIAN
Assumes Pi has Samba server running with mount point as /

$ sudo apt-get install cifs-utils
$ sudo mkdir /media/Data

TRY AND COMPILE

$ source .profile
YOU CAN NOW JUST COMPILE WITH make
$ cd /media/Data/home/pi/openFrameworks/apps/myApps/emptyExample
$ make
TROUBLESHOOTING
If you get errors the key offender is that some libraries in RPI_ROOT are linked with absolute paths. This should have been fixed with the running of fixQualifiedLibraryPaths.sh but there could possibly be exceptions
The way to fix is to find the link (e.g. with libm)
$ find ~/RPI_ROOT/ -name libm.so
#returned /home/pi/RPI_ROOT/usr/lib/arm-linux-gnueabihf/libm.so
$ cd /home/pi/RPI_ROOT/usr/lib/arm-linux-gnueabihf/
$ rm libm.so
$ ln -s ../../../lib/arm-linux-gnueabihf/libm.so.6 libm.so
#!/bin/bash
#This script is ugly, feel free to fix it
if [ "$#" -ne 2 ]; then
echo "usage ./cmd target-rootfs target-toolchain"
exit -1
fi
#passed args
ROOTFS=$1
TOOLCHAIN=$2
if [ -x $TOOLCHAIN ]; then
echo "Passed valid toolchain"
MACHINE=$($TOOLCHAIN -dumpmachine)
DEB_MULTI_ARCH_MADNESS=$ROOTFS/usr/lib/$MACHINE
fi
CURRENTDIR=$PWD
function adjustSymLinks
{
echo "Adjusting the symlinks in $1 to be relative"
cd $1
find . -maxdepth 1 -type l | while read i;
do qualifies=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | grep ^/lib)
if [ -n "$qualifies" ]; then
newPath=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | sed -e "s,\`,,g" | sed -e "s,',,g" | sed -e "s,^/lib,$2/lib,g");
echo $i
echo $newPath;
sudo rm $i;
sudo ln -s $newPath $i;
fi
done
}
adjustSymLinks $ROOTFS/usr/lib "../.."
if [ -n "$DEB_MULTI_ARCH_MADNESS" -a -d "$DEB_MULTI_ARCH_MADNESS" ]; then
echo "Debian multiarch dir exists, adjusting"
adjustSymLinks $DEB_MULTI_ARCH_MADNESS "../../.."
fi
cd $CURRENTDIR
