Failed to create DisplayPort IP Core Example Design under Windows

Dear Support Community,

I am using Intel Quartus under MS Windows and I want to use the Intel DisplayPort IP Core for Cyclone V FPGA.

As a start, I want to create the example design. To configure this, just before creating the core, the example design can be selected with a checkbox to be generated. The example design is then located under a directory "cv" below the DP IP core directory including readme.txt.

The example design has to be created using the NIOS shell and by executing the script runall.tcl, which fails.

I checked Nios shell and also Windows WSL (version 1) correctly installed. Also PATH variable is correctly set to the Quartus binaries.

First I noticed that I had to patch all filenames of Quartus binaries in the script with additional ".exe."

But I still have the error, that calling "build_ip.tcl fails executing quartus.sh and returns

Info: Command: quartus_sh -t build_ip.tcl
Der Befehl "rm" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.
------------------------------------------------

while executing
"qexec "rm -rf clkrec""
(file "build_ip.tcl" line 28)
------------------------------------------------
Error (23031): Evaluation of Tcl script build_ip.tcl unsuccessful
Error: Quartus Prime Shell was unsuccessful. 1 error, 0 warnings
Error: Peak virtual memory: 4630 megabytes
Error: Processing ended: Mon Jan 20 17:03:34 2025
Error: Elapsed time: 00:00:00
Error: Total CPU time (on all processors): 00:00:00

This is strange, because quartus_sh.exe is a shell and should have the internal tcl commands and linux commands available.

I tested different Quartus versions, 17, 19, 21 etc. alle the same

--> How do I generate the DP-IP Example design under Windows?

Thanks a lot in advance
