Re: [mosquitto-dev] Building mosquitto on mac os x 10.9.4

[Davy De Waele <ddewaele@xxxxxxxxx>]

Hi,

Thanks for the quick response !

I installed libwebsockets using brew (it was the 1.3 version) and I got it up and running !

Will see if I can get the released 1.4 up and running as well.

Thanks a lot for the tip !

Hi Davy,

There are bugs in the unreleased version of libwebsockets. I would
suggest using the released libwebsockets 1.4.

Generally I wouldn't recommend using the development version of
libwebsockets, the project isn't shy about making API/ABI changes
between releases.

Cheers,

Roger
