Porting

Porting software to the BlackBerry QNX is fun, at least that's what we think.

Workflow

1. Copy an existing port directory to a new one

cd ports
cp -R curl myport
cd myport

2. Adjust and run ./build.sh
3. Needs to patch an error out?

mkdir patches
cd ../../work/myport-1.2.3
cp offending.c offending.c.orig
diff -u offending.c.orig offending.c > ../../ports/myport/patches/offending.c.patch

4. Go back to the port directory and re-run ./build.sh, et voila!

Tips

1. Expect that the first build of your beloved POSIX-compatible program will fail

• Embrace it, this is a cool opportunity to learn something new

3. Use the source, Luke. See how the other Berrymuch ports work and the patches they bring.
4. You can find a lot of cross-compilation wisdom in the Termux Packages repo. Despite being Android-specific it has a lot of useful nuggets you can apply for Berrymuch.
5. Some good QNX-specific patches can be found in the RIM's pkgsrc repo

• Some 6000 packages were ported to QNX i386 back in 2012!
