There are two ways to install Voiceglue. The easy way, and the hard way. The easy was has the advantage of being, well, easy, but has the disadvantage of supporting only a small number of configurations and a small number of platforms. The hard way is, well, harder, but has the advantage of potentially being able to support any unix-y system in arbitrary configurations.

If you're fine with running Voiceglue on the same box as Asterisk and are going to run it on Ubuntu 8.04 or 8.10 or Fedora 9 or 10, then by all means try the easy method.

The easy way is mostly automatic. Voiceglue provides a script that should get everything installed and running in one shot. Before the script can run, however, you have to do some preparation work.

The prerequisites must be satisfied before installing Voiceglue.

You must be installing on one of the following platforms:

• Ubuntu 8.04 (Hardy)
• Ubuntu 8.10 (Intrepid)
• Fedora 9
• Fedora 10

Voiceglue has been tested and runs on both 32-bit and 64-bit versions of these OSes.

You must have Asterisk installed somehow. The Voiceglue installer doesn't check for an asterisk package, so it's fine to install it from source if you want to.

Supported versions of Asterisk are:

• Asterisk 1.2
• Asterisk 1.4
• Asterisk 1.6

The “asterisk” user must be present. This user is what the voiceglue process runs as because it needs to share audio files with Asterisk. It is legal, even with the easy way, to have Asterisk installed on a separate machine from Voiceglue, but the “asterisk” user must be present on the voiceglue host, and should match the uid/gid of the “asterisk” user on the Asterisk host.

There are several software packages that Voiceglue requires. The installer looks for them as packages in the system (debs for Ubuntu, rpms for Fedora) so they must be installed that way. For Ubuntu you use apt/synaptic, for Fedora you use yum/yumex. Here's the list of what's required on each of the supported platforms:

If an entry is blank, it means I didn't have to install that package from a base system because it was already present, so you probably won't have to either.

* I don't have an 8.10 box to test, but since it's a recent change I'm assuming it was continued in newer versions.

Without libsox-fmt-all in ubuntu sox will not be able to determine the type of file you are trying to encode, and fail. If you get “cannot find file” errors, go to /var/lib/asterisk/voiceglue/tts and try to manually encode the file using sox:

sox <filename> -r 8000 <filename.out.wav>

if you get this error:

sox soxio: Failed reading `Hello_World_This_is_a_Voice_X_M_L_test-DCC6DCF954C093C9.wav.16khz.wav': unknown file type `auto' 

you don't have the right codecs installed Note that in voiceglue 0.9 the dependency checker does not check for pkg-config, so that one will not get caught for you if it's missing.

After prerequisites are installed, download and upack the voiceglue distribution. It can always be found at http://voiceglue.org by clicking on the “Download” tab at the top.

I'm assuming that downloading and unpacking a tar file is not hard for a voiceglue user. After all, you installed Asterisk, didn't you?

From within the top-level voiceglue directory (the one containing doc), run the following command as root:

doc/install-voiceglue

It first checks the prerequisites listed above, then if those are satisfied, builds and installs all of the software required for Voiceglue. Check the output for errors.

After the script runs to completion,. you should have the following services ready to run:

• dynlog
• phoneglue
• voiceglue

On Fedora systems, you need to run chkconfig to turn them on for automatic system startup.

These services must be brought up in the order shown above, and brought down in the reverse order. Their install scripts will do this automatically on system startup and shutdown.

The prerequisites are the same as for the easy way, except that you are not necessarily restricted to the platforms listed there, and the software packages don't necessarily need to be installed as the package format of choice for the distribution.

The Voiceglue distribution contains the following top-level directories:

Each of these items (except doc) must be installed.

The order in which the software components must be installed is:

1. Cam-Scom
2. dynlog
3. Vgluefftw
4. Satc
5. phoneglue
6. SRGSDTMF
7. libvglue-headers
8. openvxi-3.4+vglue
9. libvglue
10. Vxglue
11. voiceglue

Each perl library can be installed with the following sequence of actions:

1. Change to that directory
2. Run: perl Build.PL
3. Run: ./Build install

Each program can be installed with the following sequence of actions:

1. Change to that directory
2. Determine which Makefile is appropriate for your situation
3. Run: make -f Makefile install

The libvglue software is installed in two steps. The first step installs just the headers:

1. Change to that directory
2. Run: make install-headers

When it's time to install libvglue binaries, do:

1. Change to that directory
2. Run: make install

This is the most challenging install step, as it consists of a large number of C/C++ modules that have dependencies on several system libraries.

First, look at the exports file at the top level. It contains the following definitions:

• SWISBSDK - The top-level directory of OpenVXI
• XERCESDIR - The directory containing the Xerces-C distribution
• SPIDERMONKEYDIR - The directory containing the Mozilla SpiderMonkey distribution
• JSCFLAGS - The CFLAGS used for compiling against SpiderMonkey
• JSLIBFLAGS - The library flags for linking against SpiderMonkey

These definitions have to all be correct and loaded into environment variables for the following steps to work.

Next, look at the build-openvxi script in the same top-level directory. It encodes the steps to build OpenVXI. Hopefully, with proper settings in exports, it will run successfully.

Finally, the install-openvxi script in the same top-level directory installs the compiled OpenVXI library files and runtime support files to their system destinations.
