Hi, i tried to cross compile dcmtk on my Mac by using compile script like this(targert arch is ARM):

Code:
#! /bin/bash

#
# Program  : iphone3.1-configure
# Authors  : Michael Aaron Safyan (michaelsafyan@gmail.com)
# Synopsis :
#            This program runs the "configure" script generated by the
#            GNU Autotools in order to cross-compile thirdparty libraries
#            for the iPhone 3.1 SDK. Run this script while in a directory
#            containing an autotools "configure" script. Once you run this,
#            you can use "make" and "sudo make install" to build the library.
#            An install prefix of "/opt/iphone-3.1/" is used.

i thik i'm close to solve this problem. The output is:

But how to disable runtime checks? i think that is solution.
I will be grateful for any help.
