I just downloaded the Wixel SDK from github and SDCC from souceforge. I tried make and got the following error:
Creating libraries/lib/radio_com.lib
/bin/sh: sdcclib: command not found
make: *** [libraries/lib/radio_com.lib] Error 127
From the SDCC documentation sdcclib was removed from the package in 3.8 and sdar replaced sdcclib.
I edited the makefile, and set AR := sdar#, this gave me the following error:
Creating libraries/lib/radio_com.lib
sdar: two different operation options specified
make: *** [libraries/lib/radio_com.lib] Error 1
I edited the make file again with the following changes:
AR_FLAGS = -rc
ARCHIVE_COMMAND = $(AR) $(AR_FLAGS) $@ $^
This solved the issue, hopefully it was the correct way to fix the issue
