Using latest ruby-gnome2 from git.

So with the recent change to rbpangocairo.c, I get a compile failure

Error is:  
rbpangocairo.c:40: error: ‘CAIRO\_FONT\_TYPE\_USER’ undeclared (first use  
in this function)

Looking at the latest cairo.h file it looks like CAIRO\_FONT\_TYPE\_USER  
was added in cairo 1.8.

I’m still stuck using cairo-1.2.4(supporting under RHEL 5.9)

This leaves me with this for the typedef in cairo.h  
typedef enum \_cairo\_font\_type {  
CAIRO\_FONT\_TYPE\_TOY,  
CAIRO\_FONT\_TYPE\_FT,  
CAIRO\_FONT\_TYPE\_WIN32,  
CAIRO\_FONT\_TYPE\_ATSUI  
} cairo\_font\_type\_t;

Where as the newest is

typedef enum \_cairo\_font\_type {  
CAIRO\_FONT\_TYPE\_TOY,  
CAIRO\_FONT\_TYPE\_FT,  
CAIRO\_FONT\_TYPE\_WIN32,  
CAIRO\_FONT\_TYPE\_QUARTZ,  
CAIRO\_FONT\_TYPE\_USER  
} cairo\_font\_type\_t;

I was thinking I could put something like this to check the version

# if CAIRO\_CHECK\_VERSION(1, 8, 0)

But not sure what else I would do. Other than maybe if older than 1.8  
use the previous version where it just returned…  
return GOBJ2RVAL(pango\_cairo\_font\_map\_new());

But I see kou put those changes in for a specific bug fix. I’m happy to  
play around with it and do a pull request. Just not sure of the best way  
to fix it.

Thanks

You can disable rg\_s\_create() (Pango::CairoFontMap.create)  
by “#if CAIRO\_CHECK\_VERSION(1, 8, 0)”!

## Thanks,
