Expat Support

[Matt Cupp]

Hi,

I'm trying to port Fontconfig to an embedded system (the Wii via DevkitPro).  I am having lots of difficulty porting libxml2, so I did searching and found that Fontconfig used to use Expat.  According to what I could find by searching through the mailing list and stuff and "./configure --help", Expat should still be supported.  I tried adding the option --disable-libxml2 (as described in the configure help) but configure still stops after looking for libxml2 saying it wasn't found.

So does anyone know if Expat is still supported?  Or know how hard it would be to reenable it?  Or have any other suggestions as to what I could do?  My ultimate goal would be to port Cairo to the Wii with FreeType support (hence requiring FontConfig).

Thanks,
Matt

No, expat isn't supported. I originally thought it would be fairly easy
to switch between libxml and expat, and was encouraged to use libxml
because many other applications were using that, and having two xml
parsing libraries in core at once doesn't make a lot of sense.

It would be great if you wanted to try and figure out how to make expat
work again; fontconfig doesn't have any complicated demands on an XML
parser.

Hello.

  Is this still true?  The other distros I've looked at (Fedora, Debian,
SuSE) link against expat and I have no problem building and using
fontconfig on a system without libxml2 installed.  If libxml2 is the
preferred XML library why is it described as a fallback in the configure
message and why aren't other distros using it?

Thanks,
