Description Anil Jangity 2006-08-29 10:43:39 UTC

I was able to install this on Solaris in the past. Not sure if something had
changed on my system since then or not.

When I do a make install it hangs and starts to use up *lots* of memory:

# make install
....
/data/Source/fontconfig-2.3.95/fc-cache/.libs/fc-cache:
"/usr/openwin/lib/X11/fonts/Xt+": caching, 0 fonts, 0 dirs
/data/Source/fontconfig-2.3.95/fc-cache/.libs/fc-cache:
"/usr/openwin/lib/X11/fonts/encodings": caching, 0 fonts, 0 dirs
/data/Source/fontconfig-2.3.95/fc-cache/.libs/fc-cache:
"/usr/openwin/lib/X11/fonts/misc": ^C 

fc-cache fails for that last directory.

Here is a pstack of a manual run of that same command:

Do you see anything wrong there?


Thanks.

Comment 1 Keith Packard 2006-09-01 13:04:11 UTC

Can you run fc-cache just on that directory with FC_DEBUG set to 128?

Looks like FreeType cannot decompress this file for some reason. The good news
is that the font isn't useful anyway; it's not unicode encoded and we haven't
any way to decode its charset.

Please file a bug with the FreeType folks and pass them the font file; when
decompressed FreeType opens it quite happily, when compressed, the LZW code gets
wedged.

To work around this bug, just decompress the file. Note that you can use gzip to
recompress it; FreeType appears happy enough to decode that compression scheme.
