+
+# Local Source Debug with GDB
+
+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 not find symbols anymore
+
+
+```
+    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
+        ...
+        NOTICE: API UNICENS added
+        NOTICE: Waiting port=1234 rootdir=.
+        NOTICE: Browser URL= http://localhost:1234
+    (hit Ctrl-C to break the execution)
+    info sharedlibrary afb-*
+```
+
+
+# Running an debugging on a target
+
+```
+export RSYNC_TARGET=root@xx.xx.xx.xx
+export RSYNC_PREFIX=/opt    # WARNING: installation directory should exist
+
+mkdir $RSYNC_TARGET
+cd    $RSYNC_TARGET
+
+cmake -DRSYNC_TARGET=$RSYNC_TARGET -DRSYNC_PREFIX=$RSYNC_PREFIX ..
+make remote-target-populate
+
+    ./build/target/start-${RSYNC_TARGET}.sh
+    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
+
+Note that Netbeans impose to set debug directory to ./build/pkgout or it won't find binding symbols for source debugging
