A Makefile is included with the default locations for SDK and tools. I recommend installing the latest version of xCode and associated iOS SDK for it to compile. Also required is the "codesign" tool which i think also comes with xCode, a signing certificate is included in the bundle.
type "make" to compile
Copy the compiled dynamic library using ftp or scp e.g:
desktop $ scp ./touchHook.dylib root@<IP address of phone>:/usr/lib/touchHook.dylib
send the following command using ssh to the device e.g:
desktop $ ssh root@<IP address of phone>
Register the environmental value:
iDevice# launchctl setenv DYLD_INSERT_LIBRARIES "/usr/lib/touchHook.dylib"
Run an application and start touching the screen, the status bar at the top should change color or move (may require a few touches for it to work)
I recommend disabling the hook library after use:
iDevice# launchctl setenv DYLD_INSERT_LIBRARIES ""
