Dear Mac-R-users

I installed the rgl package via the R-GUI installation menu as a  
binary (version 0.79).
I use the R- 2.7.1 and i run it on a intel Mac (Leopard 10.5.4).

The command rgl.open() gives me the following error:

error in rgl.open() : Cannot create font, error code: 1

Any suggestion to solve my problem?


Thanks

Yours Faithfully,

Christoph Hofer

There are problems with the font handling in 0.79 on MacOSX.  Your 
options are to rebuild from source without including the FTGL/Freetype 
handling, or go back to 0.77, or to figure out what's wrong with the 
configuration and fix it (and then tell me or Daniel what's needed!)

Another suggestion:

Don't use rgl.open, use open3d.  But before you do that, try

r3dDefaults$useFreeType <- FALSE

I don't know how to get FTGL/Freetype to run properly on MacOSX, but 
this avoids trying.

# 
in src/ext/FTVectorizer.cpp lines 8-9 change

#ifdef __APPLE_CC__
     typedef GLvoid (*GLUTesselatorFunction)(...);

to

#ifdef __APPLE_CC__
     typedef GLvoid (*GLUTesselatorFunction)();

then rgl compiles on OS X (using g++-4.0, even with FTGL)

I believe the first line is needed in 10.4.  Is there a conditional to 
select just that version?

Thanks, that looks simple, and rgl still compiles in Tiger.  I'll commit 
the change as soon as I have an Internet connection again.

I'm still seeing problems with the display of glyphs: it appears that 
FTGL is not reading what FreeType sends properly, or FreeType is not 
reading the .ttf file properly.  For now I'm going to set 
useFreeType=FALSE on MacOSX.  It might help if FTGL could specify fonts 
by their characteristics, so I could use cairo or pango the way other 
devices do  -- but FTGL isn't currently being maintained.  Maybe it 
would be worth the effort to figure out what's going on in it and adding 
this myself.
