zbasic errors #17

Closed kendallgreen closed 3 years ago

On Ubuntu 20.04 LTS with Ryzen 1600, 8GB ram, with $PATH = /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/ken/zipcpu/sw/install/cross-tools/bin

git clone https://github.com/ZipCPU/zbasic cd zbasic make

After cloning zbasic, I got the following errors running make ar --transform s,^,date +%Y%m%d-zbasic/, -chjf date +%Y%m%d-zbasic.tjz find sw -name "*.cpp" find sw -name "*.c" find sw -name "*.h" find sw -name "*.sh" find sw -name "*.py" find sw -name "*.pl" find sw -name "*.png" find sw -name Makefile find rtl -name "*.v" find rtl -name Makefile find sim -name Makefile find sim -name "*.cpp" find sim -name "*.h" find sim -name "*.c" find . -name "*.txt" find . -name "*.html" find . -name "*.xdc" find auto-data -name "*.txt" README.md verilator -Wall -Wno-TIMESCALEMOD --MMD -O3 --trace -Mdir ./obj_dir -y wbuart -y wbubus -y cpu -y rtc -y sdspi -cc main.v %Error: Unknown warning specified: -Wno-TIMESCALEMOD make[1]: [Makefile:77: obj_dir/Vmain.h] Error 1 make: [Makefile:140: verilated] Error 2

This appears to be a Verilator version issue. At one point I had to add -Wno-TIMESCALEMOD to get ZBasic to build with Verilator and -Wall. It seems as though prior versions of Verilator didn't support this check, but future versions wouldn't pass the design without it. For now, just remove -Wno-TIMESCALEMOD from the rtl/Makefile and run make again.

I'm open to suggestions of how to deal with this in the future.
