compiler does show only character position, not the line number

Yes, by default it shows you the character position, because it's faster to go to character position in vim :goto number

In case you still want to use line numbers then pass -l option to voc

voc -ls m.Mod

compilation crashes on ARM or Raspberry Pi with recent (like 3.12) kernels.

echo 1 > /proc/sys/vm/legacy_va_layout

should fix that.

make errors on freebsd

make -f makefile.freebsd.clang.x86_64

make: "/root/voc/makefile.freebsd.clang.x86_64" line 22: Need an operator make: "/root/voc/makefile.freebsd.clang.x86_64" line 24: Need an operator make: Fatal errors encountered -- cannot continue make: stopped in /root/voc

use gmake.
