Cannot build ramdisk_tools about iphone-dataprotection HOT 5 CLOSED

Hi, you need to fix manually the SDK path in the following line in the Makefile 
:
CFLAGS=-Wall -arch armv6 -isysroot 
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk/

Hello. 
Thank you for the prompt response.
I followed your instructions and pointed the cflags to the right SDK.

this is the console output while make-ing:

You need ldid, that you can download here
http://code.google.com/p/networkpx/downloads/detail?name=ldid&can=2&q=
Place it somewhere in your path like /usr/bin or /usr/local/bin

Worked as a charm. Thank you very much :)
onto trying to puzzle all the pieces together now.
