Forth code debugging
by sachin.b＠soc-soft.com Oct. 13, 2004

Oct. 13, 2004

Hi Everyone, I have written some code in forth and trying to integrate it in the Openbios kernel-1.1. Build procedures says: Building final dictionary... failed I look into the obj-x86/openfirmware.log for the reasons of failure. For any undefined reference it straight says "undefined word". But for some logical errors it sys: Segmentation violation at 1 (or some address location) What is this segmentation violation? What information this violation location gives? Could any one tell me how to debug code in this environment?

Anyway I keep on adding hooks to the same kernel instead of once again making Changes for cross compilation in the new kernel. If u can give me the links and Changes needs to be applied I'll do it myself....
