Building FreeSwitch from source under De{bi,vu}an
FreeSwitch does not let just anyone download its "open source" software any more. You need to have a Personal Access Token.
Once you have a PAT, you can use it to fetch the FreeSwitch GPG keyring, and set up apt authentication:
wget -O /usr/share/keyrings/signalwire-freeswitch-repo.gpg https://signalwire:pat_xxxxx12345xxxxx@freeswitch.signalwire.com/repo/deb/debian-release/signalwire-freeswitch-repo.gpg echo "machine freeswitch.signalwire.com login signalwire password pat_xxxxx12345xxxxx" >/etc/apt/auth.conf.d/freeswitch.conf chown root: /etc/apt/auth.conf.d/freeswitch.conf chmod 600 /etc/apt/auth.conf.d/freeswitch.conf
You also need to include a reference to the GPG key in sources.list:
deb [signed-by=/usr/share/keyrings/signalwire-freeswitch-repo.gpg] https://freeswitch.signalwire.com/repo/deb/debian-release/ buster main deb-src [signed-by=/usr/share/keyrings/signalwire-freeswitch-repo.gpg] https://freeswitch.signalwire.com/repo/deb/debian-release/ buster main
Then you can finally start getting the source code…

Need to get 579 MB of archives. After this operation, 1,535 MB of additional disk space will be used. Do you want to continue? [Y/n]
Incidentally, what the devil is FreeSwitch (a telephony system) doing installing stuff for OpenCV (a computer vision library)?
Building the package
When you first run dpkg-buildpackage -b -uc -us you'll probably find that it terminates with an error message: checking for libks >= 1.8.2… configure: error: You need to either install libks or disable mod_verto in modules.conf
Hm, so much for build-dep installing everything you need to be able to build the package…
Even more mysterious: libks is installed: State: installed (1.7.0-75~buster-75), upgrade available (1.8.2-79~buster-79)
Huh? Why isn't it upgraded?
Running aptitude upgrade now wants to upgrade 143 packages, of which 141 have names starting with freeswitch, one is libfreeswitch1 and one is libks. Weird.
After this, dpkg-buildpackage -b -uc -us spends a long time doing something which looks pretty much like you'd expect it to (assuming you've compiled things in the past).
There are an interesting number of messages during the build process along the lines of:
dpkg-shlibdeps: warning: package could avoid a useless dependency if debian/freeswitch-mod-lua/usr/lib/freeswitch/mod/mod_lua.so was not linked against libcrypto.so.1.1 (it uses none of the library's symbols)
This possibly also indicates why a binary installation of FreeSwitch brings in such an astonishing number of additional packages…
Finally, after 25 minutes, the build process finished with:
dh_shlibdeps: Aborting due to earlier error make: *** [debian/rules:43: binary] Error 255 dpkg-buildpackage: error: fakeroot debian/rules binary subprocess returned exit status 2
Oh, very helpful. What was the "earlier error" I wonder?
A repeat run of dpkg-buildpackage -b -uc -us (which presumably has to do far less work, since everything buildable has already been built, and therefore might show the error message where you can see it, rather than several hundred lines up your scroll buffer) still takes 6 minutes to do whatever it wants to, and this time ends with the message:
mv: cannot move './debian/libesl-perl/usr/lib/debug' to './debian/libesl-perl-dbg/usr/lib/debug': Directory not empty make[1]: *** [debian/rules:98: override_dh_strip] Error 1 make[1]: Leaving directory '/home/antony/freeswitch-1.10.9~release~21~a615e85afc~buster' make: *** [debian/rules:43: binary] Error 2
Huh.
So, starting again from scratch (delete the source tree, download it again, re-build) but this time teeing the output to a file results half an hour later in a 5 Mbyte text file, containing the significant line:
dpkg-shlibdeps: error: no dependency information found for /usr/lib/x86_64-linux-gnu/libsystemd.so.0 (used by debian/freeswitch/usr/bin/fs_epmd)
After installing libsystemd0 (which is available in Devuan), the package builds.
Or, should I say, packages: it actually creates 347 of them!
Still, at least it builds now.
Changing the version "number"
It took me quite some time to work out how to change the version number of the packages being built.
The version I started from was downloaded as freeswitch-1.10.9~release~21~a615e85afc~buster and this was building packages with the version 1.10.9~release~21~a615e85afc~buster-1~buster+1
After looking for and in various files which might contain the string buster+1 I eventually discovered that the version to build is simply taken from the first version listed in the debian/changelog file. This came as something of a surprise to me.
The first version listed was:
freeswitch (1.10.9~release~21~a615e85afc~buster-1~buster+1) stable; urgency=medium
I added some lines to the top of the file, starting with:
freeswitch (1.10.9~release~21~enhancedMWI) stable; urgency=medium
and then build process then created packages with version 1.10.9~release~21~enhancedMWI.
However, this changes the version of the packages being built, but strangely does not change the version reported by FreeSwitch once it is running:
# fs_cli -x "version" FreeSWITCH Version 1.10.9-release-21-a615e85afc~64bit (-release-21-a615e85afc 64bit)
That is my next objective…
