[Freeswitch-users] mod_flite fails due to undefined symbol: cmu_lex_init

Thu Sep 6 18:34:14 UTC 2018

 Nathan,
After build and install flite to /usr/local, I build freeswitch as below,
1. ./devel-bootstrap.sh --prefix=/home/kxie/freeswitch-dev-install2. change modules.conf to enable flite3. make4. make install

   kaiduan - when you _built_ freeswitch, did you make sure it built using the extra libs you installed manually?

  I do custom builds of all of the dependent libs on my box (ubuntu 16), and install into /local/fslibs/install, and then during build I use: 
      export PKG_CONFIG_PATH=/local/fslibs/install/lib/pkgconfig:/usr/share/pkgconfig
     cd /local/freeswitch/src
     ./configure -C --disable-fhs --prefix=/local/freeswitch/server

  At that point I don't have to set any env vars to get FS to launch.

 I don’t see this issue on debian.  ld.so.conf might fix it, or building to /usr instead of /usr/local.  Check out our debian directory for how we build the packages for debian as a hint.  On debian 9 we just started using system packages as they now have working flite 2.0 in the distro, see master for the patches necessary for that to work without pkg-config (which unfortunately the debian package does not have)  
  Our deb directory is here:  https://freeswitch.org/stash/projects/SD/repos/libflite/browse/debian 
  You might want to use the src from this git checkout as I’m not sure the tarball has our debian packaging in it or not.

    With the command as below, 
   LD_PRELOAD="/usr/local/lib/libflite_cmu_us_kal.so /usr/local/lib/libflite_usenglish.so /usr/local/lib/libflite_cmulex.so  /usr/local/lib/libflite.so" ./bin/freeswitch 
  I finally got mod_flite working on Ubuntu 16.04 with Freeswitch 1.8.0 source code 
  So the question is why Freeswitch does not load above libraries by itself?

       Thanks Michael. 
  I downloaded the flite 2.0 from http://files.freeswitch.org/downloads/libs/flite-2.0.0.tar.gz and build it as below 
  ./configure --enable-shared make make install 
  build and run freeswitch-1.8, the same error occurred again. 
  However mod_flite was successfully loaded if I ran freeswitch as below (used LD_PRELOAD  to load libflite_cmulex) 
   kxie at kxie-Inspiron-3656:~/freeswitch-install$ pwd /home/kxie/freeswitch-install kxie at kxie-Inspiron-3656:~/freeswitch-install$LD_PRELOAD=/usr/local/lib/libflite_cmulex.so ./bin/freeswitch

    Our build requires flite 2.0 …. Our latest Debian unstable and  1.8 repos have these packages, for ubuntu you likely need to build these packages yourself from our support deps in stash.

    Hi all, 
  I build and run FreeSwitch  1.6.20 from source on Ubuntu 16.0.4  xenial, the mod_filte  failed while loading, 
   2018-08-3019:03:30.786468 [CRIT] switch_loadable_module.c:1522 Error Loading module  /home/kxie/freeswitch-dev-install/lib/freeswitch/mod/mod_flite.so **/usr/local/lib/libflite_cmu_us_slt.so.1: undefined symbol:  cmu_lex_init** 
  Any idea to solve this  issue? 
  Many thanks,
