XeTeX in TeXLive: No AAT feature supported

[quinon@…]

It seems that XeTeX in TeXLive (XeTeX 3.1415926-2.2-0.9997.4 (TeX Live 2010/MacPorts 2010_2)) does not understand AAT font features at all.

Attached are XeTeX sample source files included in <​http://scripts.sil.org/cms/scripts/render_download.php?&format=file&media_id=xetex_doc_094&filename=XeTeX_doc.zip> pdf files produced by typesetting them, and log files.

As you see:

• AAT-info.pdf says "No AAT features available" for Apple Chancery font.
• Geeza Pro's Arabic characters are not ligatured in Arabic.pdf.
• font-features.log says "Unknown feature" for all AAT features invoked by font-features.tex.

Please fix the problem.

Thanks,

Kino

Does it work if you rebuild texlive-bin with the +atsui variant?

texlive does not build support for AAT unless explicitly requested with +atsui. Unfortunately, the ATSUI libraries are deprecated and not available on 64 bit, so this also requires it and all of its dependencies to be built as 32-bit -- which is why it's not the default.

Sorry for my inattention. I will remember to do so the next time.

Thank you very much for the instruction and the explanation. I run the following:

sudo port -v upgrade --force texlive-bin +atsui

It took a very long time but now XeTeX works with AAT fonts just fine.

Thanks again.

I also added a note to the texlive-bin port about this that will appear if it's built without +atsui (r76456).
