[MeeGo-dev] fennec(Illegal instruction) issue on MeeGo

[Paul Li]

Hi Auke,
	Thank you so much for your suggestion, but I am sure these parameters are supported by our processor, because I have compiled others apps and can be run on our processor using the same compiling parameters. Any other reason?

Best Regards
Paul

you broke it.

"illegal instruction" means that you instructed the compiler to generate 
processor instructions that are invalid for your processor type.
