[Freeswitch-users] mod_pocketsphinx link error on Mac OS X 10.6 (solved)

[Bruce Fletcher]

Thanks to bkw_ and some other friendly IRC helpers, it has been established that indeed the MacPorts install that I mentioned below was the source of my _iconv linker problem.  I'll just record a few things here on the mailing list as Google fodder in case someone else hits this same problem, and maybe make a small note somewhere in the wiki.

FreeSWITCH on Mac OS X assumes a standard Mac OS X build environment, and it appears that MacPorts can make things a bit non-standard.  I only had MacPorts installed to get the git-core port, and I've verified that uninstalling MacPorts and installing git from a disk image works fine.  Disk images of git are available here:

 http://code.google.com/p/git-osx-installer/downloads/list?can=3

Two other experiments to report.  I removed the MacPorts directories of /opt/local/bin and /opt/local/sbin from my $PATH and FreeSWITCH built and loaded fine, although the above git disk image install was required for 'make current'.  I then tried leaving the /opt dirs at the end of my path, and again ran into the _iconv problem below.  So if you need MacPorts on your computer for some other reason, you may have to selectively disable it in your $PATH whenever you want to build FreeSWITCH unless you can come up with some more elegant solution than I could.  I was a little unimpressed with how installing git from MacPorts required 17 other ports first, so I'm happy to go the "git from .dmg" route myself.

Thanks again everyone,
- Bruce
