Hi Ross,
It works! I just built it by hand, so I’ll write a simple makefile for it
tomorrow. Only issue is that the version of Freetype 2 that comes with OS X
doesn’t seem to know about FT_Orientation, so I just ifdeffed out the
few bits that referred to that, possibly at the expense of handling certain
cases (Postscript fonts which are wound the other way, perhaps? I dunno).
|
Hmmm, interesting. txt2dat is currently compiled against 2.1.9, I haven’t
tried upgrading since txt2dat is the only thing I use it for. But the API doc
at the freetype site still documents
the FT_Orientation API. Also, version 2.3.1 (which I just downloaded to
check) seems to include it. What version do you have?
|
I believe it is freetype 2.1.4 (based on the major/minor/patch definitions in
freetype.h). The headers are last dated 2002, and a look at more recent
freetype changelogs suggests that predates the introduction of
“FT_Orientation.” It’s annoying that the preinstalled libraries aren’t more up
to date.
| |
It also documents
the FT_OUTLINE_REVERSE_FILL flag, which I do vaguely remember from when I
originally wrote the program, and can’t remember why I didn’t use it. Does
your version support that flag? If so, I’ll look into using that instead.
Type 1 (Postscript) fonts are wound the other way (at least the ones I have
are) so we do need to take it into account.
|
Yes, FT_OUTLINE_REVERSE_FILL is defined on my system.

I have a proposition: working out a Mac build is great, but what would you
say to adapting txt2dat to run on the web (like Bitsticker)? Even more
than my Mac crusade, I like the idea of making all these LDraw tools more
accessible to the casual user, who may not be so keen on the command line or
even just installing lots of little programs. I’d be willing to work on
that, when possible, and I could even host it since my web server supports
compiled CGI “scripts.”
|
That’s also a great idea, but I’ll still continue to maintain the stand-alone
executable separately, so it’ll be up to you to incorporate any changes I may
make to the original :) Either way, I’m happy put a to link on my page.
|
Cool. I don’t think any modifications to txt2dat itself will even be
necessary: I’ll write a CGI script that passes it arguments and returns its
output. That would make it easy to keep the web version in sync with the regular
version.
I just checked and txt2dat builds on my server no problem (it has FT 2.1.9).
I’ll work out my makefile later today.
Jim
