System Workbench for STM32

While I would agree the problem is harmless if the compilation runs and you get the binaries, it doesn't seem harmless when that DOESN'T happen. I see failure on the very first build that I try. Here are the last two lines from the Console:
arm-none-eabi-gcc: error trying to exec 'cc1': execvp: No such file or directory
make: *** Drivers/STM32L4xx_HAL_Driver/stm32l4xx_hal.o Error 1

When I look at my Settings, as suggested, I see the ${openstm32_compiler_path} path variable pointed to, but I have no idea what the value of it is. How would I find it out?

I suspect there is a problem with my installation of the software, but I have no idea how to find out what that probem is.

Thanks for any assistance.
