Hi,what does the err info mean?

[Altera_Forum]

Hi all, 

 When I compile a project in NiosII IDE(shipped with QuartusII 4.2),there too often comes  out a err message:   Error hello_world *** [E:/files/My_module_try_nios/Nios_sim/dummy_file] Error 2     And I did find out this so-called "dummy_file" and it's just an empty file without anything.  So could any one tell me why this err comes out and what leads to this err?  Thanks so much!   Regards,  Don

I don't know why? Maybe it is like the "dummyfile" in linux. 

 You can try: 1. create a dummyfile manually 2. re-generate in SOPC with Enable "simulation with modelsim"

Thanks to mountain8848! 

 I tried your sugestions to me,but it seemed that the err came out still... http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif   Now I&#39;m using QuartusII4.2 and NiosII1.0,do you think this might   have business with the version of the two software?

NIOS Editor aka Eclipse tends to do that sometimes. Try starting from a helloworld project and copying your code instead of a blacnk project.   just my two cents regards pavan

http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif oops, you did use hello_world.  

 could you please check the following?  (1) did you save the file after modification, The IDE does not auto-save neither does it notify the user (2) if it still does`nt work , just restart IDE and it works sometimes for me  regards pavan

as for what problem you posted above, i have meeted it also.in my opinion,it had to do with the version of the software.because afger i tried to update my quartus to version 5.0,meanwhile,i work it smoothly without the problem you had meeted. 

good luck
