[ft] Anyone able to get freetype to compile for iPad?

[address@hidden]

The configure script invocation that has been working great for me for 
several months with the iPhone-only version of my app is now choking 
when trying to build for the iPad.

This works:

./configure --prefix=/usr/local/iphone --host=arm-apple-darwin 
--enable-static=yes --enable-shared=no 
CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin9-gcc-4.0.1 CFLAGS="-arch armv6 -pipe -mdynamic-no-pic -std=c99 -Wno-trigraphs -fpascal-strings -fasm-blocks -O0 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=2.0 -gdwarf-2 -mthumb -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/include/libxml2 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk" CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp AR=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar LDFLAGS="-arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk -Wl,-dead_strip 
-miphoneos-version-min=2.0"


This does not:

./configure --prefix=/usr/local/iphone --host=arm-apple-darwin 
--enable-static=yes --enable-shared=no 
CC=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/arm-apple-darwin10-gcc-4.2.1 CFLAGS="-arch armv7 -pipe -mdynamic-no-pic -std=c99 -Wno-trigraphs -fpascal-strings -fasm-blocks -O0 -Wreturn-type -Wunused-variable -fmessage-length=0 -fvisibility=hidden -miphoneos-version-min=2.0 -gdwarf-2 -mthumb -I/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/include/libxml2 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk" CPP=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/cpp AR=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar LDFLAGS="-arch armv7 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk -Wl,-dead_strip 
-miphoneos-version-min=2.0"


The invocation differences are:

armv6 --> armv7
arm-apple-darwin9-gcc-4.0.1 --> arm-apple-darwin10-gcc-4.2.1


The failure looks like:

Strangely, when I leave "armv7" but roll back to 
"arm-apple-darwin9-gcc-4.0.1", it will complete successfully and then 
"make" runs fine.  But, I need to be using 4.2.x for iPad builds, so I 
need to get this working with the 4.2.1 gcc.



I posted this on the iPhone SDK forum as well, but it may be something 
specific to the freetype config system, which is pretty complicated, so 
I figured it couldn't hurt to cross post it here.  The other one's not 
getting mu attention anyway.


Anyone know how I might be able to get this to work?

Thanks.
