Why does Quartus project compilation fail in the Intel® Quartus® Prime Pro Edition Software (Linux version) within Nios® V Command Shell?

Description

This is observed in the Intel® Quartus® Prime Pro Edition Software version 21.3 for Linux when compiling a Quartus software design within Nios® V Command Shell. For example,

• Using the Intel Quartus Prime Software within the Nios® V Command Shell

1. Launch the Nios® V Command Shell.
2. Launch the Intel® Quartus® Software in the command shell.
3. Perform a hardware compilation using Processing ➤ Start Compilation.

 

• Using command line interface within Nios® V Command Shell

1. Launch the Nios® V Command Shell.
2. Perform a hardware compilation using quartus_sh --flow compile <Project Name> in the command shell.

This is due to the incorrect Linux environment variable settings by Nios® V Command Shell, which causes compilation failure in the Intel® Quartus® Prime Pro Edition Software or through Nios® V Command Shell command line flow.

 

Resolution

To work around this for the Linux environment, exit the Nios® V Command Shell before compiling a project. Any design compilation should not be done within the Nios® V Command Shell.

This only affects project compilation with no impact to Nios® V utilities script (niosv-*).

This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 21.4
