Pango build failure

[hasso.tepper@…]

Pango fails to build on Snow Leopard (10.6.8) and Xcode 4.2. I've tried to clean the port, also tried to switch compiler from clang to llvm-gcc.

Hmm, the errors seem to start with:

:info:build /usr/lib/clang/3.0/include/stddef.h:31: syntax error, unexpected '(' in 'typedef __typeof__(((int*)0)-((int*)0)) ptrdiff_t;' at '('
:info:build /usr/lib/clang/3.0/include/stddef.h:35: syntax error, unexpected SIZEOF in 'typedef __typeof__(sizeof(int)) size_t;' at 'sizeof'

pango builds fine on every OS X version I test on, which includes Snow Leopard, but I don't have access to Xcode 4.2 on Snow Leopard so maybe its version of clang is too old, but then I'm surprised using llvm-gcc-4.2 didn't work.

At first - these errors you pointed out are "normal". They are there on successful builds since ages. But I also tried Xcode 3.2.6 on Snow Leopard and pango fails to build there as well.

But I also found this - ​https://bugzilla.gnome.org/show_bug.cgi?id=688356

And this - ​http://git.gnome.org/browse/pango/commit/?id=7274bd56db3ce2f02594687a307d22aa99c787c4

I can confirm that this patch fixes the issue for me.

Replying to hasso.tepper@…:

Ok, then I guess the error to look at is:

But I also tried Xcode 3.2.6 on Snow Leopard and pango fails to build there as well.

I still wonder what is different about your system, since on my Snow Leopard system with Xcode 3.2.6 it builds fine.

But I also found this - ​https://bugzilla.gnome.org/show_bug.cgi?id=688356

And this - ​http://git.gnome.org/browse/pango/commit/?id=7274bd56db3ce2f02594687a307d22aa99c787c4

I can confirm that this patch fixes the issue for me.

That bug was reported against glib 2.35.x but in MacPorts we have glib 2.34.x... unless you're using the glib2-devel port instead? Even so, I installed glib2-devel on my Snow Leopard machine and was unable to reproduce a pango build failure.

I'm might commit this patch anyway, since upstream has already put it in their repository, but I would feel better about doing so if I could reproduce the failure first and verify the patch fixes it.

What version of the gobject-introspection port do you have installed? ("port installed gobject-introspection" would tell you)

[ryandesign (Ryan Carsten Schmidt)]

pango was updated to 1.32.5 which includes the patch you referred to so hopefully this problem is now fixed for you.
