NOTES.md

by Brendan O'Connor (http://brenocon.com)

I got all of ocropus to compile on Mac OSX 10.6, though I haven't tested it much yet. This is the current version inside the ocropus hg repository, so approximately version 0.5, with iulib perhaps 0.4ish.

See ocroinst.osx -- the first file in "everything_besides_iulib.diff" -- for line-by-line instructions; the script may even just run. We're assuming Homebrew and pip (see the comments).

iulib.diff was generated from

cd iulib
hg export tip

everything_besides_iulib.diff was generated from

(hg diff; for d in */.hg; { d=$(dirname $d); echo "====== DIRECTORY $d"; (cd $d && hg diff) })  > everything_besides_iulib.diff

which is hacky, but the mercurial setup is too complicated for me to figure out anything else. Is everything divided into tiny little sub-repositories or something? It's inconvenient.

Regarding TIFFHeader, it seems that it was deprecated in favor of the three new headers, each an exact binary representation of TIFF header structures: TIFFHeaderClassic for ClassicTIFF, TIFFHeaderBig for BigTIFF, and TIFFHeaderCommon for the parts of the TIFF header they both share. So it may be best to use TIFFHeaderCommon. Maybe. Who knows. I'm still just trying to install the thing.
