Description Olivier Crête 2017-04-10 21:38:23 UTC 
macOS comes with bison 2.3, but we need 2.4 to build GStreamer. This is also the version required by the autoconf script.

Apple adds an extra string in their version.

Meson encountered an error in file subprojects/gstreamer/gst/parse/meson.build, line 21, column 15:
Uncomparable version string 'Apple(flex-31)'.

$ flex --version
flex 2.5.35 Apple(flex-31)

here is a patch that fixes it for me.

Meson doesn't have regexes?

Nop, this is a hard design choice.
