AFB-daemon dependencies
OpenSuse >=42.2, Fedora>=25, Ubuntu>=16.4 AGL Binary packages installation from this wiki
For other distro see chapter # Building AFB-daemon from source on Standard Linux Distribution
Specific Dependencies
- alsa-devel >= 1.1.3 Warning some distro like Fedora 25 still ship version 1.1.1 as default
NOTE: On Ubuntu 16.4 you should recompile AlsaLib from source as today latest stable is 1.1.4.
OpenSuse
- Alsa-devel zypper install alsa-devel # 42.3 is shipped default with 1.1.4
Fedora 26 (out of the box) - Alsa-devel 1.1.4
Ubuntu-16.4 - Alsa should be recompiled from source
wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.1.4.1.tar.bz2
tar -xjf alsa-lib-1.1.4.1.tar.bz2
cd alsa-lib-1.1.4.1
./configure --prefix=/opt
Ubuntu-17.04 (out of the box) - Alsa 1.1.4
WARNING: do not forget to upgrade your PKG_CONFIG_PATH=/opt/lib/pkgconfig or whatever is the place where your installed alsa.

# Note:
1) Controller is now a standalone project and should added on top of project bindings
2) If you want monitoring add '--alias=/monitoring:$HOME/opt/afb-monitoring' (should point to monitoring HTML5 pages)
3) To expose AAAA control interface add '--ws-server=unix:/var/tmp/afb-ws/ctl-aaaa'
afb-daemon --workdir=. --ldpaths=. --binding=../../afb-controller/build/afb-source/afb-control-afb.so --port=1234 --roothttp=../htdocs --token="" --verbose
Warning: See below net on GDB requiring (--workdir=.)
Note: GDB Source Debug limits/features
Warning: technically AGL bindings are shared libraries loaded thought 'dlopen'. GDB supports source debug of dynamically loaded libraries, but user should be warn that the actual path to sharelib symbols is directly inherited from DLOPEN. As a result if you change your directory after binder start with --workdir=xxx then GDB will stop working.
Conclusion: double-check that --workdir=. and run debug session from ./build directory. Any IDEs like Netbeans or VisualCode should work out of the box.
Examples:
# WORK when running in direct
afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs
# FAIL when using GDB with warning: Could not load shared library ....
gdb -args afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs
...
warning: Could not load shared library symbols for ./build/ucs2-afb/afb-ucs2.so.
Do you need "set solib-search-path" or "set sysroot"?
...
To debug sharelib symbol path: start your binder under GDB. Then break your session after the binder has loaded its bindings. Finally use "info sharedlibrary" and check 'SymsRead'. If equal to 'No' then either you start GDB from the wrong relative directory, either you have to use 'set solib-search-path' to force the path.
gdb -args afb-daemon --workdir=.. --ldpaths=build --port=1234 --roothttp=./htdocs
run

firefox http://localhost:1234 # WARNING: do not forget firewall if any
ssh -tt ${RSYNC_TARGET} speaker-test -twav -D hw:ep01 -c 2
Note: remote-target-populate will
- create a script to remotely start the binder on the target in ./build/target/start-on-target-name.sh
- create a gdbinit file to transparently debug remotely in source code with gdb -x ./build/target/gdb-on-target-name.ini
- to run and debug directly from your IDE just configure the run and debug properties with the corresponding filename
- run a generic control and pass virtual channel as a parameter (check remaning PCM in plugin)
Note that Netbeans impose to set debug directory to ./build/pkgout or it won't find binding symbols for source debugging
Building AFB-daemon from source on Standard Linux Distribution
Handle dependencies using packager > (OpenSuse-42.2, Fedora-25, Ubuntu 16.04.2LTS)
Using system package repositories:
- gcc > 4.8
- systemd-devel (libsystemd-dev>=222)
- libuuid-devel (OpenSuse) or uuid-dev (Ubuntu)
- file-devel(OpenSuSe) or libmagic-dev(Ubuntu)
- libjson-c-devel
- ElectricFence (BUG should not be mandatory)
- libopenssl-devel libgcrypt-devel libgnutls-devel (optional but requested by libmicrohttpd for https)
Using AGL repositories:
- libmicrohttpd>=0.9.55 (as today OpenSuse-42.2, 42.3 or Ubuntu-16.4 ship older versions)
- afb-daemon from AGL Gerrit
