Error, while compiling ruby/pango on my mac

Desktop Ruby-Gnome 2
1

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 (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?

What about the following patch?

I thank you for your quick responce.
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.

And could you show your ‘ruby extconf.rb’ output and mkmf.log?

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