Good afternoon,
I had a question about this particular thread. I'm trying to
cross-compile for an ARM Cortex-A8 target running Linux, and I'm failing
the various "configure" tests. Think I'm addressing some of the same
issues that you saw when building for another ARM environment.
Were you ever successful cross-compiling for your iPhone?
