[Freeswitch-users] building mod_opal and v1.2stable

Sun Jan 27 23:24:47 MSK 2013

Hello,

I did fill two Jira bugs, one for mod_323 and another for mod_opal.

Just wanted to remind that since those two do not work, at least for me,
there is no more any support in FS 1.2 stable for H323.

So I ask again did someone succeeded in having any of those 2 working  with
1.2 stable on a Linux platform ?

Gilbert,

Thank you for collecting all of this information. You did quite a bit of
work and that will help the developers figure out what's going on. Would you
mind creating a ticket at jira.freeswitch.org and adding all this
information? That will help the developers keep track of the issue and avoid
any unnecessary delays.

Thanks!

Hello,

I succeeded in building mod_opal, but it crash FreeSWITCH (segmentation
default) after simple test.

Here are the steps on Debian "squeeze".

After getting all required packages including swig

Advice,  check that you do not have any version of ptlib or h323plus or opal
already somewhere.

use find /- name "*libpt*.so"

use find /- name "*libopal*.so"

My FreeSWITCH is in /usr/local/src/ and I am root when I build.

cd /usr/local/src/

svn co
https://opalvoip.svn.sourceforge.net/svnroot/opalvoip/ptlib/tags/v2_12_0/
ptlib-2.12.0

cd /usr/local/src/ptlib-2.12.0

./configure  --disable-plugins --disable-v4l2 --prefix=/opt/lib

make && make install

export PKG_CONFIG_PATH=/opt/lib/lib/pkgconfig 

cd /usr/local/src/

svn co
https://opalvoip.svn.sourceforge.net/svnroot/opalvoip/opal/tags/v3_12_0
opal-3.12.0

cd /usr/local/src/opal-3.12.0

./configure --disable-plugins --prefix=/opt/lib

make && make install

As the install fails to copy include/ep/

cd /usr/local/src/opal-3.12.0

mkdir -p /opt/lib/include/opal/ep ; chmod 755 /opt/lib/include/opal/ep ; (
for fn in include/ep/*.h ; do /usr/bin/install -c -m 644 $fn
/opt/lib/include/opal/ep ; done);

Please notice that the mkdir line is one long line.

Add mod_opal to your modules.conf

Go to your mod_opal src dir in my case 

cd /usr/local/src/freeswitch/src/mod/endpoints/mod_opal

Edit mod_opal.h

You need to change 2 lines

#include <opal/localep.h> 

to

#include <ep/localep.h>

then 

#define HAVE_T38 (OPAL_CHECK_VERSION(3,11,2) && OPAL_T38_CAPABILITY)

to

#define HAVE_T38 0

Now you can build mod_opal type make 

Go back to your FS dir and do make and make install to check all is ok.

Before launch FreeSWITCH you need to set LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/opt/lib/lib

start your FreeSWITCH 

Then try to call extension 9197 it should work despite the errors lines like

2013-01-24 03:12:25.597058 [WARNING] switch_core_codec.c:802 Codec is not
initialized!

2013-01-24 03:12:25.597058 [ERR] switch_core_timer.c:117 Timer is not
properly configured.

In my case I have a sip phone registered to FS at extension 1000

If I call from openphone this extension

the call get thru, I pick up but mod_opal isn't  aware of this and when I
hang up on the sip phone FreeSWITCH crash.

Do you mean you built opal in /root/opal? You shouldn't build things as
root, but that's not the reason for your troubles.

I have to say I'm a bit puzzled, it looks like you've installed opal to
multiple locations.

/usr/local/freeswitch/opal looks the best match (opal/localep.h) but it's in
the wrong location.

/usr/local/src/freeswitch/libs/opal/include/ep/localep.h

Not sure why it's installed here, opal isn't shipped under libs/

/usr/local/include/ep/localep.h

/usr/include/ep/localep.h

Close but the directory is wrong as it needs to be opal/localep.h, not
ep/localep.h

/usr/include/opal/localep.h

Should be the correct filename, but you don't have a copy.

It could be a change in the opal library but I find that unlikely since it'd
break apps using the library like FS. More likely there's a problem with the
prefixes given to opal's configure command.

As I  said earlier, I installed ptlib and opal in /root directory.

2013/1/23 Steven Ayre <steveayre at gmail.com>

It's localep.h, not local.h:

Sorry, seems my phone did an annoying autouncorrection!

Thanks for reply, Steven!

Tried to search local.h file, but search returned nothing. That are all
local.h files in my system:

/usr/local/src/freeswitch/libs/spandsp/src/gsm0610_local.h

/usr/local/src/freeswitch/libs/spandsp/src/t30_local.h

/usr/local/src/freeswitch/libs/spandsp/src/t42_t43_local.h

About -devel packages - at first tried to install ptlib, opal and -devel
from yum but their versions have been too low for mod_opal.

2013/1/22 Steven Ayre <steveayre at gmail.com>

Run:

find / -name local.h

It's failing to include opal/local.h. All the other errors are because its
missing the definitions in that file.

Normally I would say to instal the -devel package, but since you built from
svn that doesn't apply. Perhaps it's not installed or installed to the wrong
place. The find command will tell us where that file is.

ptlib and opal are  the last version obtained from svn as it is said in wiki
<http://wiki.freeswitch.org/wiki/Mod_opal> .

but just a bunch of errors after make mod_opal http://pastebin.com/HHUPLCLV

The latest version of opal in Debian (even in Sid) isn't new enough for
mod_opal. It needed various features added that are only only available in
the svn version.

The wiki page states you have to install ptlib and opal from svn - this is
why.

http://wiki.freeswitch.org/wiki/Mod_opal

Of course that can then cause conflicts unless you package it yourself or
install a dummy package, or problems with other libraries/apps that are
built against the libopal that's already packaged.

Ptlib and h323plus/opal are also notorious for having to get matching
versions. If you don't pair exactly the right version of ptlib with the
specific version of h323plus/opal you can get instability problems. So the
official Debian ptlib package probably wouldn't be good with opal from
svn...

As for mod_h323, it does compile and work, at least on Wheezy and possibly
Squeeze too. I've never had any luck getting mod_opal working but have got
mod_h323 working. I don't actively use it though - all my traffic is
currently SIP.

Another option is to run Yate as a SIP->H323 proxy. It only handles the
signalling, media still goes directly caller->FS. It worked quite well,
although it would occasionally crash - but at least that only dropped the
H323 calls and didn't take FS down with it, and Yate automatically
restarted. That was on Lenny so a long time ago...

Has anyone succeded in building mod_opal ?

Should I go with mod_h323 instead ?
