Use meson as build system

[infirit]

It builds but is untested.

AFAICS $GST_CVS is not set anywhere so -Werror is never added to the gstreamer cflags. I'll add that a bit later and anything I still find in configure.ac.

It should be good to go now. Let me know if you need anything changed.

Thank you very much! I've no previous experience with meson, but I'll try this out in a couple of days. (and my apologies for the delayed reaction)

[infirit]

No problem. Meson puts all its files in a build directory of which you can have multiple.

So a typical setup may be: meson --buildtype debugoptimized debugoptimized meson --buildtype debug debug meson --buildtype plain build

Then in each of those directory run ninja and it starts the build. Add -v to ninja for it to be verbose.

Setting a higher --warnlevel for the debug build may be good as it revealed a potential problem with signed and unsigned ints, see below.

../plugin/gstmoodbar.c: In function ‘calc_barkband_table’:
../plugin/gstmoodbar.c:293:17: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
   for (i = 0; i < NUMFREQS (mood); ++i)
                 ^

Beside it being fast I like that meson and ninja are much more understandable than autotools. You can actually figure out what it does by reading build.ninja :open_mouth:.

Yeah, thank you! Indeed, I'm impressed by the speed, and seems to be understandable, too. Works for me; will test around a bit more, update the README and installation instructions and commit everything in a couple of days(tm).

[Mazhoon]

Okay, merged and updated the installation instructions a bit. Again, apologies for my procrastination (this is my only project on github, so it got pushed back too easily). Thank you for your effort!
