Description

lttng version used: ===================
userspace-rcu : mar-04 8bcbd94a60f624c1faae1481fcb0888aec25b481
lttng-ust : mar-02 bf1175c265545d44e4a898e0bc520d366cd7882a

Problem: ========
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

Work around: ============
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.
