Why do I get ERROR: SOPC_KIT_NIOS environment variable not set?

Description

Due to a problem in the Quartus® Prime Pro Edition Software 24.2 for Linux, when generating a BSP with NIOS® V, you might see an error related to the SOPC_KIT_NIOS environment variable and thus be unable to generate a BSP.

Resolution

To workaround this problem, add the SOPC_KIT_NIOS2 environment variable as follows:

export SOPC_KIT_NIOS2=1

This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition Software.
