Error in processing. System NOT successfully generated.

Can anyone help to understand what this means I as stated b4 am a noob to this nios. So details will be greatly appreciated

Thanx in advance

Here's the source of the error you're seeing:

eperl: SOPC_KIT_NIOS2 environment variable not set

How did you get to this point? SOPC_KIT_NIOS2 should be added to your environment when installing Nios II. Providing more details of what you've done, to get here, as well as what versions of Quartus II and Nios II you are using would certainly help us to help you.

thanx a lot slacker, the post helped me identify source of the problem. i set the path as you suggested. now its working and generating the .bdf file.
