Hardware testing on a native Apple Silicon Mac (LTspice XVII 17.2.4) surfaced
that model/subcircuit-bearing circuits failed with 'Unable to find definition
of model' / 'Could not open library file': native Mac LTspice in batch mode
does NOT auto-include the standard device libs or search the lib dir the way
Wine does (Wine netlists the .asc itself on Linux, so this never showed there).
Two fixes:
- netlister.py: emit .lib standard.{bjt,mos,dio,jft} for each semiconductor
family present, since Mac LTspice won't auto-include them in batch mode.
- runner.py: _resolve_lib_paths() rewrites bare-name .lib/.include refs to
absolute paths under the Mac lib root before running -b (Mac LTspice can't
find them by name). darwin-only; Linux path untouched.
- test_netlister.py: skip the Wine-oracle comparison class when wine is absent
(it's a Linux-only oracle).
Validated on hardware: full suite 534 passed / 8 skipped on native macOS
(all 10 integration circuits simulate, incl. op-amp + BJT); Linux unchanged
(524 unit + 18 integration). Also answered Kevin's open questions on hardware:
#2 -- 'LTspice -b <netlist>' DOES run over bare SSH (Background session), so
mcltspice is fully headless on Mac since it always netlists itself; #3 --
examples are not pre-extracted on Mac (examples_exist reports false).
