Goal

Update a bitbake file from a previous version to a newer version.

This is mainly just to help me remember. If you'd like clarification as to what I'm doing here, please comment.

Example: Node.js

Currently the Node.js available through OpenEmbedded is v0.2.1. Today I'll be updating it to v0.2.6.

Update to the latest current version from OpenEmbedded:

cd ~/overo-oe/org.openembedded.dev/recipes/nodejs
git fetch
git checkout org.openembedded.dev ./

Move the file the most recent version. Then update the source and md5sums:

git mv nodejs_0.2.1.bb nodejs_0.2.6.bb
cat nodejs_0.2.6.bb | grep 'http'
PV=0.2.6
wget http://nodejs.org/dist/node-v${PV}.tar.gz
md5sum node-v${PV}.tar.gz
sha256sum node-v${PV}.tar.gz
sed -i "s/\(md5sum.* = \)\".*\"/\1\"`md5sum node-v${PV}.tar.gz | cut -d' ' -f1`\"/" nodejs_${PV}.bb
sed -i "s/\(sha256sum.* = \)\".*\"/\1\"`sha256sum node-v${PV}.tar.gz | cut -d' ' -f1`\"/" nodejs_${PV}.bb

Recreate patches:

bitbake nodejs # fails, of course

cd ~/overo-oe/tmp/work/armv7a-angstrom-linux-gnueabi/nodejs-0.2.6-r1/

cp node-v0.2.6/deps/libev/wscript node-v0.2.6/deps/libev/wscript.orig
vim node-v0.2.6/deps/libev/wscript # set execution of time code to false
git diff --no-prefix \
  node-v0.2.6/deps/libev/wscript.orig node-v0.2.6/deps/libev/wscript \
  > ~/overo-oe/org.openembedded.dev/recipes/nodejs/files/libev-cross-cc.patch

cp node-v0.2.6/wscript node-v0.2.6/wscript.orig
vim node-v0.2.6/wscript # allow arm, mips, x86, x64 cross compiling
git diff --no-prefix \
  node-v0.2.6/wscript.orig node-v0.2.6/wscript \
  > ~/overo-oe/org.openembedded.dev/recipes/nodejs/files/node-cross-cc.patch

bitbake nodejs # now it works again
