Re: Cygwin Hosted Linux (x86) targetted cross compiler problem

Dan,

Thanks for the template. 

Further, I find that you are using 

AS=$(IXIA_CROSS_TOOL)gcc -ml instead of $(IXIA_CROSS_TOOL)as.

Is there a purpose for this or a typo.

In billgatliff.com, I found only gcc/ranlib/ar are taken care not as.

Throw some light on this.

Regards,

babu k
