Thanks for the reply Giovanni.  I have done the steps on the wiki.

tl;dr; should i put a prefix when i'm making the dependent mods so they don't go into /usr/local/lib, or this is why ldconfig is run - to tell the system where the libs are.

All the relevant stuff is below

Hope you can see something wrong,
Cheers
Chris

e.g.
here is my bash history

 1050  cd freeswitch/
 1051  ls
 1052  find . -name gsmlib
 1053  cd src/mod/endpoints/mod_gsmopen/
 1054  ls
 1055  cd gsmlib/
 1056  ls
 1057  cd gsmlib-1.10-patched-13ubuntu/
 1058  ls
 1059  ./configure
 1060  make
 1061  make install
 1062  ldconfig 
 1063  cd /usr/src/freeswitch/src/mod/endpoints/mod_gsmopen/libctb-0.16/build
 1064  make DEBUG=1 GPIB=0
 1065  make DEBUG=1 GPIB=0 install
 1066  ldconfig
 1067  cd /usr/src/freeswitch/src/mod/endpoints/mod_gsmopen/
 1068  make clean
 1069  make install

Just to repeat the compilation error

you must first compile and install libctb, as per the wiki page (
http://wiki.freeswitch.org/wiki/gsmopen )
then, after installation of libctb and gsmlib (as per wiki), be sure
to update your dinamic link cache, or compiler will not find then.

Eg: ldconfig

All good GM, no inconvenience, just a minor gotcha  ;)
I am unable to compile mod_gsmopen though.

It complains about not being able to find ctb-0.16
The actual filename is libctbd-0.16.so in /usr/local/lib as you can see from
the 2nd lot of stuff.

How do I fix this?

yes, it requires libspandsp, maybe the Makefile it's not yet tweaked
to build the library automatically.

So, please first build mod_spandsp, then mod_gsmopen.

We'll fixx the Makefile soon, sorry for the inconvenience.

Hi FS List,

FYI - as a shortcut to building my freeswitch, I skip spandsp - but it
looks
like this mod_gsmopen wants it in there.
