I really can't comment much on 'no luck' - if it doesn't
compile or install there will be error messages.

jkmeter -h

Not the meter. But normally you'd use this meter with a
calibrated monitor gain, at least for mixdown or mastering.
You use pink noise at -20dB RMS (recent versions of jnoise
and japa will provide exactly that level, it indicates 0dB
on the k20 meter and -6 on the k14)) and adjust the volume
for 83 dB(C) from each speaker, then never touch it again.
Some people have reported that this is quite a high level.
You can use a lower one, the important part is to keep the
monitor gain fixed. You will then over time learn to
correlate the meter and what your ears tell you.

will you be so good as to listen to me ?
