Create the Patch

BePorter? will apply the patch in the directory where the source package was extracted. For this to work, you need to create the patch like this:

1. Place the directory (for example, named xyz-1.0.0) containing the original sources in a directory of your liking
2. Place the directory containing the patched sources in the same directory. You'll need to rename it first, of course (say xyz-1.0.0-haiku
3. Now create the patch with

   diff -Naur xyz-1.0.0/ xyz-1.0.0-haiku/ > xyz-1.0.0.patch
   

Don't forget to clean your sources directories first (make distclean, for example).

Congratulations! The generated patch is BePorter? compatible.

Note: when creating a patch from a svn or a similar repository, the developers of that software package will typically prefer it to be created from the top-most directory. However, BePorter? currently requires the patch to be created in the parent of that top-most directory.

As example, image we wish to create a patch of Haiku's OptionalPackage? file. Yes, I realize this is a horrible example.

cd /path/haiku/
cd ../
svn diff haiku/build/jam/OptionalPackages > ~/OptionalPackage-<new-pkg>.patch
