I did now (with 14.4.0 on an amd64 OpenBSD):
If libsndfile with FLAC and Vorbis compiled in
is found during ./configure, but FLAC and Vorbis is not
(which is a typical situation, as libsndfile is searched
for via pkg-config, and is found, unlike FLAC and Vorbis,
which are not), then the build will pick up and link against
the libsndfile, but the resulting SoX binary is not able
to handle flac and ogg ("no handler"), eventhough the flac
and ogg functionality is present, UNLESS told explicitly:
$ sox /tmp/file.wav /tmp/file.flac
sox FAIL formats: no handler for file extension `flac'
$ sox /tmp/file.wav -t sndfile /tmp/file.flac
$ sox /tmp/file.wav /tmp/file.ogg
sox FAIL formats: no handler for file extension `ogg'
$ sox /tmp/file.wav -t sndfile /tmp/file.ogg
Would it be possible to have SoX figure itself that the flac
functionality is available (through libsndfile) and just use it,
without having to specify it explicitly?
If OTOH both flac and vorbis and flac- and vorbis-capable libsndfile
are found during ./configure, it picks up and links against them
(obviously), and when flac or ogg functionality is needed, sox
just uses libvorbis or libflac directly, without going through
libsndfile:
$ sox /tmp/file.wav /tmp/file.flac
$ sox /tmp/file.wav /tmp/file.ogg
