Hello everyone, I’ve raised the issue some days ago but I haven’t received response ☹ in short, gtk2 has not gdkpixbuf2 listed as a dependency. I believe it should have - even the smallest possible sample fails if gdkpixbuf2 is not installed. I’ve prepared a patch (included here) that includes the dependency in the rakefile (it’s ONE line of code, but still - I’ve done my homework). Please let me know - there is maybe a good reason that I don’t know about for which gdkpixbuf2 shouldn’t be included.

Ruby/GdkPixbuf2 shouldn’t dependes on Ruby/GTK2. Ruby/GTK2 depends on Ruby/GdkPixbuf2 is correct. Could you write a patch to move gdkcairo.h related codes in rbgdk-pixbuf.c to Ruby/GTK2? ## Thanks, kou ---

Hi, I didn’t submit the issue to the bug tracker - just here on the mailing list: I wasn’t sure it was an issue to begin with. Ruby/GdkPixbuf2 does not depend on Ruby/GTK2. The problem is that Ruby/GTK2 does depend on Ruby/GdkPixbuf2 but, on the gem manifest, the dependency isn’t listed and so the Ruby/GdkPixbuf2 gem does not get installed as it should when installing the Ruby/GTK2 gem. The little patch I submitted (included in my last message here) was a fix for the gtk2 rakefile - it just added the gdkpixbuf2 dependency. > Could you write a patch to move gdkcairo.h related codes in > rbgdk-pixbuf.c to Ruby/GTK2? I’ve taken a look at rbgdk-pixbuf.c and I believe that this is the section you’re talking about: #if RBGDK\_PIXBUF\_CHECK\_VERSION(2,8,0) && defined(HAVE\_RB\_CAIRO\_H) # include \ # include \ # define CAIRO\_AVAILABLE 1 #else # define CAIRO\_AVAILABLE 0 #endif problem is, I have absolutely no idea where to move it. I’ve tried rbgtk.h in gtk2/ext with no luck. Any pointer would be appreciated - I’d like to know more about the project and be able to help but I lack the necessary knowledge. Andrea ---

Hi, enclosed to this mail you’ll find the patch. I tested everything on my machine and it builds/installs fine, also my examples and the examples in gdk\_pixbuf2 run fine. I really hope I didn’t break anything… Hope this will help! Andrea ---

Hi Kouhei, I’ve updated from trunk and built/reinstalled the gems and everything works on my machine. Thanks for your work! Andrea
