Build Problems..unrecognized instruction

Hi...

I'm trying to merge Nios/quartus hardware with software.

File structure is:

C:

Project_File

Software (this contains all the C code, etc)

Quartus_stuff (This contains all the Quartus files, including the .PTF file)

I enter the IDE and:

File> Import> Existing Altera Nios II project into workspace> browse to Software folder

File >new >other > (select Altera Nios II system library) and 1) name it "my_syslib" 2) location is C:/Project_File/Quartus_stuff 3)SOPC Builder system is the .PTF file

Then: Set properties of project so project references and Associated System library point to the library created in previous step

Then: Project > Rebuild Project.

Things go along well, then I get a ton of error messages

First is: Can't open nios_Macros.s for reading: no such file or directory

THen a ton of "Error: unrecognized instruction GEQU

Evidently, my path to My_syslib/cpu_0_sdk/inc/nios_macros.s is invalid or not recognized.

I can see this file in the navigator.

WHAT AM I DOING WRONG?????? TOTALLY GRATEFUL FOR ANY HELP!!!

Thanks!
