[cairo] Building pixman for iOS/iPhone

[suzuki toshiya]

Hi,

I remember there was a post asking for the info how to
cross-build cairo (not pixman) for iOS in a month ago:
http://lists.freedesktop.org/archives/cairo/2010-December/021328.html

Similar inappropriate configuration (specification by
CC & --host) was given and it made the configure script
failed. I'm wondering if there is a person who promotes
wrong way of cross-build and some iOS users were trapped.

Regards,
mpsuzuki

I would have thought it should be looking in usr/lib/ under the appropriate  platform folder (eg. /Developer/Platforms/iPhoneOS.platform/Developer/usr/lib/gcc/arm-apple-darwin10/4.2.1/) which only contains a crt3.o file...
