Application-X , that tries to link to lttng library: " -lttng-ctl",
fails to compile with the following error:
/local/scratch/lmctdlt/my_DX_SYSROOT//usr/lib/liblttng-ctl.so: undefined reference to `opt_quiet'
collect2: ld returned 1 exit status
make: *** [temp_app] Error 1
Have to define var "opt_quiet" in Application-X.
However, there is no information on how this var should be used on the Application side.

Indeed. The sessiond communication library uses the error.h file which export opt_quiet to quiet outputs across the code base.
The fix will be to rename this variable to lttng_opt_quiet and declare it in the library as a global variable.
Future version will probably implement a lttng_set_quiet API call but not for 2.0-stable.
