Why does the fpga_crossgen compiler not point to the correct GCC toolchain when using the Quartus® Prime Pro Edition Software version 19.3?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 19.3, the fpga_crossgen compiler incorrectly points to multiple gcc install locations.

Resolution

To work around this problem, please add the toolchain_dir to the path when executing the fpga_crossgen compiler

fpga_crossgen --gcc-toolchain=<toolchain_dir>

where

<toolchain_dir>:= /intelFPGA_pro/19.3/hls/gcc

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