[Pixman] Building pixman for iOS/iPhone

[Rob Cas]

Hi,

I was wondering if anybody has information on how to build pixman for iOS/iPhone.

I'm running Snow Leopard 10.6.5, Xcode 3.2.4 and want to use the iPhoneOS4.1 SDK. Details are below.

Thanks in advance,
	Rob.

I've tried setting the following environment variables:

CPPFLAGS="-pipe -no-cpp-precomp -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk/usr/lib/gcc/arm-apple-darwin10/4.2.1/include/ -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk/usr/include -I/Developer/Platforms/iPhoneOS.platform/Developer/usr/include"

CFLAGS="-std=c99 -arch armv6 -pipe -no-cpp-precomp --sysroot='/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk' -isystem /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk/usr/lib/gcc/arm-apple-darwin10/4.2.1/include/ -isystem /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk/usr/include -isystem /Developer/Platforms/iPhoneOS.platform/Developer/usr/include"

LDFLAGS="-arch armv6 --sysroot='/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk' -L/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.1.sdk/usr/lib -L/Developer/Platforms/iPhoneOS.platform/Developer/usr/lib"

I then call:
	./configure --host=arm-apple-darwin10

Which results in a failure:
	configure: error: C compiler cannot create executables
	See `config.log' for more details

The config.log indicates a failure to link the test program which is used to verify the compiler works:
	ld: warning: in /usr/lib/crt1.10.5.o, missing required architecture armv6 in file
	ld: could not find entry point "start" (perhaps missing crt1.o)

I don't really understand why this isn't working...why the linker is looking for the crt object file in /usr/lib/. 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...

Any ideas on what configuration I've got wrong?
