Perl

Setting up ssh for cross compiling

• Copy arm-linux scp and ssh binaries to the root of a usb drive and mount it on chumby.
• If one doesn't already exist, create a symbolic link to scp on chumby

# ln -s /mnt/usb/scp /usr/bin/scp

Building

Download

• Grab the latest stable Perl source

# wget http://www.perl.com/CPAN/src/stable.tar.gz

Configure

• Run Configure with the following paramters (replace targethost with the IP address of your chumby):

sh ./Configure -des -Dusecrosscompile \
   -Dtargethost=192.168.1.102 \
   -Dtargetdir=/mnt/usb \
   -Dtargetuser=root \
   -Dtargetarch=arm-linux \
   -Dcc=arm-linux-gcc \
   -Dusrinc=/usr/arm-linux/include \
   -Dincpth=/usr/arm-linux/include \
   -Dlibpth=/usr/arm-linux/lib

Compile

• run make
• an arm-elf miniperl binary should be created
• if you strip the binary, miniperl should be around 830K in size

# arm-linux-strip miniperl

Too Lazy?

You can download miniperl already cross-compiled for chumby, here - http://files.chumby.com/languages/perl/miniperl
