W3 on Mac OS X

W3 on Mac OS X

[Colin Fallon]

I am trying to get W3 working with emacs on Mac OS X. I have compiled
and installed the latest CVS versions of emacs, url and w3. However,
when I start W3 I get the following error in Backtrace.

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
  font-size(nil)
  font-default-size-for-device(nil)
  font-spatial-to-canonical("+12pt")
  css-expand-length("+12pt" t)
  css-expand-value(height "+12pt")
  css-parse-args(238 257)
  css-parse("file:/usr/local/share/default.css" nil nil)
  w3-find-default-stylesheets()
  w3-refresh-stylesheets()
  w3-do-setup()
  w3()
* call-interactively(w3)

I have tried rooting around in the code but can't seem to get to the
bottom of it - maybe something to do with the font specification on
Mac OS X?? Has anyone else got W3 working on Mac OS X and can you help
me with this error?

One thing to note - I am running on Mac OS X 10.1.5 as I can't afford
to upgrade to 10.2 yet.

Thanks,
  Colin

OK, I managed to track down the issue. W3 does not seem to cater for
the Mac and I have at least partly fixed this by adding the following
line to font-window-system-mappings in font.el

(mac      . (x-font-create-name x-font-create-object))

W£ now launches and seems to work.

Could you give a quick step-by-step reference for those of us who have
had far less success than you in making w3 work?

Something along the lines of Andrew Choi's how-to for downloading and
compiling EMACS from CVS:

Hi Edward,

I will give it a go and write up what I have done to date. Hopefully,
I can find the time this weekend.
