Goal

I would like to be able to cross-compile nodejs using bitbake. (I've already got it natively compiled on the Gumstix Overo)

bitbake node
opkg install node

Current Status

It compiles!!! Now I just have to finish packaging it as a bitbake recipe.

1. setup your gumstix build environment
2. Copy the recipe below and put it in the location specified, creating folders as necessary.
3. run bitbake node
4. once it fails, go in ${OVEROTOP}/tmp/work/armv7a-angstrom-linux-gnueabi/node-0.1.104-r0/node-0.1.104/ and edit the files by hand.
5. bitbake node again. It should succeed.
6. copy the raw ${OVEROTOP}/tmp/work/armv7a-angstrom-linux-gnueabi/node-0.1.104-r0/node-v0.1.104/node whereever you need it.

Files

These are the files I have so far. They still need a few tweaks before I create a bitbake recipe.

They do compile and leave the useable node binary in ${OVEROTOP}/tmp/work/armv7a-angstrom-linux-gnueabi/node-0.1.104-r0/node-v0.1.104/node.

They don't create the ${OVEROTOP}/tmp/deploy/glibc/ipk/armv7a/node_0.1.104.ipk that you would hope for... yet.

Same as above with one major change:

DEPENDS = "openssl-static"

./node-v0.1.104/deps/libev/wscript in the temp builddir

This will become files/libev-arm-cross.patch once packaged.

Currently you can modify the failed build in place from ${OVEROTOP}/tmp/work/armv7a-angstrom-linux-gnueabi/node-0.1.104-r0/
