Cross compiling rethinkdb for Raspberry Pi

Currently running Ubuntu 14.04 x86_64. I want to cross compile rethinkdb for my RPi for experimental purposes, which is supported in 1.12 (and people have apparently successfully compiled).

I have installed the toolchain:

sudo apt-get install g++-4.7-arm-linux-gnueabi gcc-arm-linux-gnueabi

export CXX=/usr/bin/arm-linux-gnueabi-g++-4.7
export CC=/usr/bin/arm-linux-gnueabi-gcc-4.7
export AR=/usr/bin/arm-linux-gnueabi-ar
export LD=/usr/bin/arm-linux-gnueabi-ld


Configuration runs:

./configure --ccache --allow-fetch --without-tcmalloc

However
make
fails,

/bin/bash: ccache: command not found


Any pointers to getting this working?

Just install ccache. It would be helpful even if you did not have this issue because it somewhat speeds the compilation up on embedded. We are also using it at the company, fwiw, even with icecream, eventually.

sudo apt-get install ccache
