NIOS II IDE question

[Altera_Forum]

Hello all, 

I followed this tutorial step to step: http://fpga4u.epfl.ch/wiki/nios_ii_project   But when I am building the project, I am getting this error: error: module cpu_0 (altera_nios2) not found in component directory (install.ptf)   this is everything i got as error: creating generated_all.mk... error: module cpu_0 (altera_nios2) not found in component directory (install.ptf) nov 23, 2010 11:04:07 pm - (severe) generate: java.lang.illegalstateexception: java.lang.illegalstateexception: com.altera.ingenuous.gtfelement.gtfelementerrorexception: <error> element in gtf script make: *** [system_description/../obj/generated_all.mk-t] error 1 build completed in 1.906 seconds   Can someone please tell me what I need to do?:(

After you have generated the Nios system with sopc builder, you should find the <sopc_name>.ptf file in your project directory and the install.ptf file in a .sopc_bulder subdirectory. This applies to Quartus 9.0, but it is probably the same with 10. 

Then, when you create a new Nios IDE project, you have to enter the previous file int the target hardware box. Have you performed these exact steps?

Yes, I got the .ptf file but I cannot find the install.ptf file. When I choose the file in the target hardware box, it automatically picks up the cpu for NIOS using that particular file, so I know thats right. What else could be the problem for the install.ptf to be missing?  

Also, as a side note, I created the NIOS II system and it also generates successfully.    This is the report at the end of generation:   # 2010.11.24 23:03:05 (*) completed generation for system: demo2.# 2010.11.24 23:03:05 (*) the following system items have been generated:  sopc builder database : h:/ece576/trial/demo2.ptf   system hdl model : h:/ece576/trial/demo2.vhd   system generation script : h:/ece576/trial/demo2_generation_script   hdl simulation directory : h:/ece576/trial/demo2_sim # 2010.11.24 23:03:05 (*) success: system generation completed. info: system generation was successful.

I am getting a similar error while building the project. Could someone please help.
