Sc-im installation error

I’m trying to install the sc-im spreadsheet program by following the instructions on this website https://awesomeopensource.com/project/andmarti1424/sc-im and I got stuck on the step of entering the command make -C /usr/src/ where the Makefile is located and I get the following output.

make: Entering directory '/usr/src'
make: *** No rule to make target 'gram.y', needed by 'y.tab.c'.  Stop.
make: Leaving directory '/usr/src'

This is my inxi output:

How do I correct this?

sc-im is available in the AUR (Arch User Repository).
