Can the requirements be lowered to pango >= 1.6, like the rest of --enable-pango? Reproducible: Always

I see this too. I've only got pango 1.6.0 over here.

Possibly; that api was needed so that we could decouple our DPI setting from pango's sniffing of the X DPI setting. It isn't possible to do that with pango pre-1.8. FC4 at least has 1.8 ;) We can possibly make this be an optional thing..

I may be totally off base as I don't know the true chain of dependency, but looks like --enable-default-toolkit=cairo-gtk2 builds thebes/nsSystemFontsGTK2.cpp, which in turn uses GetXftDPI(). It's under #ifdef MOZ_ENABLE_XFT though...

This patch at lets you build and run on Pango 1.6. We'll still "do the right thing" if Pango 1.8 is available.

Well actually I haven't tested with Pango 1.8, but that's the intent :-)

Comment on attachment 193663 [details] [diff] [review] fix I hate that we have to do this, but it'll do for now.. thanks for the quick patch. r+sr=vladimir

It looks like that patch landed on August 24. Is this fixed?

No, it's gotten even worse - cairo-gtk2 requires pango 1.10.0 now: checking for pango >= 1.1.0... yes checking _PANGOCHK_CFLAGS... -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include checking _PANGOCHK_LIBS... -lpango-1.0 -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0 checking for pango >= 1.10.0 pangocairo >= 1.10.0... Requested 'pango >= 1.10.0' but version of Pango is 1.6.0 This is on FC3, FC4 isn't better as it has pango 1.8.0.

No longer the case; we're back to 1999 with 1.6!

Er.. 1999? 1.6 first shipped in FC3, which shipped in November 2004.

Yes, the exact release date of pango-1.6.0 was 13 Sep 2004.
