Hi there. I tried to compile and install ruby/gnome2 (ver. 0.17.0rc1 ) on my system (Mac OSX 10.5, PPC G4). Everything worked fine, except the pango/ruby-package was cpmplaining, during the “make”-process. I got the following errors: rbpangolayoutiter.c:27: error: invalid application of ‘sizeof’ to incomplete type ‘PangoLayoutIter’ rbpangolayoutiter.c:28: error: dereferencing pointer to incomplete type rbpangolayoutiter.c:28: error: dereferencing pointer to incomplete type rbpangolayoutiter.c: In function ‘layout\_iter\_copy’: rbpangolayoutiter.c:27: error: invalid application of ‘sizeof’ to incomplete type ‘PangoLayoutIter’ rbpangolayoutiter.c:28: error: dereferencing pointer to incomplete type rbpangolayoutiter.c:28: error: dereferencing pointer to incomplete type lipo: can’t open input file: /var/folders/YC/YCMZBk2ZHlyLER20dBkBYk+++TI/-Tmp-[//cc6EO8Hc.out](https://cc6EO8Hc.out) (No such file or directory) make[1]: \*\*\* [rbpangolayoutiter.o] Error 1 make: \*\*\* [all] Error 2 I also tried those older versions of ruby/gnome2 (0.16, 0.15), but I got even more errors with them. GTK+ is already installed. Any suggestions? ---

So I patched the file that way: I saved your patch as a .diff file and did =\> patch --input …/patch.diff in the src dir. As I configured and compiled the pango/ruby-package once more it failed again and exactly the same errors appeared. ---

Hi, I had the same error, and I fixed it by replacing, in file “pango/src/pangolayoutiter.c” at about line 22 #if PANGO\_CHECK\_VERSION(1,6,0) with #if 0 Thereby effectively commenting out the section where the comment predicts breakage. ---

What about the following patch?

Many thanks! It works just fine. Now there is a real solution online for that issue. (… I think so)
