As stated in FreeSWITCH Jira FS5274 : http://jira.freeswitch.org/browse/FS-5274
"tgmath.h on FreeBSD is seriously broken. It expands all the functions
described in the standard, even though some of them are not implemented
yet. In this case, it expands the macro pow to cpowl, which isn't implemented.
I suggest you don't include tgmath.h on FreeBSD, at least for now."
This prevents FreeSWITCH from being compiled on FreeBSD.
How-To-Repeat: Try to build FS v1.2.Stable on FreeBSD.
FYI, I'm removing all remaining freeswitch ports in a few minutes. They were never staged.
There is new work on getting freeswitch into the ports tree, see:
