I can confirm this. It looks like Pango 1.14 (that's when this call was added to Pango) is a new requirement.

I can also confirm.

I'm a linux newbie, but I have Ubuntu Dapper with the latest official updates installed and pango is listed as 1.12.3-0ubuntu3.

Comment 4

[Hideo Oshima]

I cannot reproduce with Debian unstable.
Pango in my distro is 1.18.4.
It may be related to Pango's version.

Attachment: Update minimum pango version

This updates the minimum version of pango required for 1.9 builds.

Thanks, Bill.  While this is consistent with http://wiki.mozilla.org/Linux/Runtime_Requirements, I'd rather not enforce this unless necessary.  Some people do have their own builds with older versions.  I'll post a patch to avoid using pango_font_describe_with_absolute_size().

Attachment: use FC_PIXEL_SIZE instead of pango_font_describe_with_absolute_size

This is similar to what is done in CreateScaledFont and is actually consistent with what pango_font_description_get_size does in Pango-1.18.2.

(The fallback to point size on problems is what pango_font_description_get_size does and at least tells us whether the font has zero or non-zero size.)

I mean pango_font_describe_with_absolute_size

I agree.  It's always better not to change the build requirements
unnecessarily.

Reassigning to karlt.
