[webkit-help] Cross-compiling webkit for ARM platform on Linux-x86 machine

[Jilu Oommen]

Hi Nevo,

Thanks for your advice. It was a path issue itself and that error is 
resolved.

Now WebKit is configured with:

 JIT compilation                                          : no (CPU 
'arm' not supported)

the code I am using is the latest arm port code from Webkit site. 
(http://code.staikos.net/cgi-bin/gitweb.cgi?p=webkit;a=shortlog;h=loki/arm-port)

Please advise as to how to enable the arm port for JIT. Should be it 
modified in Makefile, or configure script

Thanks in advance,
Jil
