Large build system and small API modernizations

[dhdaines]

Ideally this would be a couple different PRs. It:

• Switches to CMake and incorporates all of SphinxBase to simplify life for people wanting to compile it.
• Removes the audio library because it is based on a totally obsolete model of audio processing (/dev/audio from good old SunOS) and it is too difficult to make a cross-platform abstraction based on this.
• Removes a few deprecated APIs (ARG_FLOAT32 and ARG_FLOAT64, and the non-reentrant parts of cmd_ln.h)
• Clarifies pointer ownership in a few places
• Hopefully fixes problems on big-endian machines (Testsuite fails on several archs sphinxbase#77 and Some tests fail on big endian architectures sphinxbase#86)
• Adds a -loglevel argument and makes logging quieter by default

The goal is to get a truly stable release since PocketSphinx is no longer a development system.

Can you make doxygen not required?

[dhdaines]

Sure, in theory it isn’t but there might be some cmake magic needed. Likewise for swig… Le mer. 8 juin 2022 à 15:42, Kevin Lenzo ***@***.***> a écrit :

Some suggestions

I'm using pyenv, and cmake seems to get a little confused about which SDK to build for -- it complains (but works) at link time about the python version and the current build target. We can figure this out later...

[100%] Linking C shared module _pocketsphinx_python.so
ld: warning: object file (/Users/kal/.pyenv/versions/3.9.9/lib/libpython3.9.a(getargs.o)) was built for newer macOS version (12.3) than being linked (12.0)

... and more like that.
