I have used the attached file yonks ago, worked fine, used to determine
which mode, inch or mm the machine is in. But now halcompile will not
build it. I've tried all the options to halcompile, but nothing works.
It seems all roads lead to the same exit:
gene@GO704:~/linuxcnc/configs/go704-xyza$ halcompile --compile units.comp
Traceback (most recent call last):
File "/usr/bin/halcompile", line 1558, in <module>
main()
File "/usr/bin/halcompile", line 1528, in main
process(f, mode, outfile)
File "/usr/bin/halcompile", line 1366, in process
a, b = parse(filename)
File "/usr/bin/halcompile", line 441, in parse
a, b = f.split("\n;;\n", 1)
ValueError: not enough values to unpack (expected 2, got 1)
It is older code from 2017, by Kurt Jacobsen
Can anyone advise?
Cheers, Gene Heskett, CET.
