Hi,
I am trying to build the Lua interpreter into the sim:nsh sample code using the
menuconfig (Applications->Interpreters->Lua). The Lua interpreter seems to be
missing libmath. I tried adding `CFLAGS += -lm` but it didn’t seem to help. Can
anyone tell me how to add the Lua interpreter correctly?
Thanks,
Russ
