Dependency on 'babeltrace' binary is not enforced #49

Closed ghost closed 8 years ago

ghost commented 8 years ago

I installed the analyses using sudo ./setup.py install on a system with the python3-babeltrace package, but not the babeltrace binary itself. No error was reported on installation.

Running for example the lttng-cputop-mi --metadata command works, but running the actual analysis does not, and the following message is printed:

Error: Cannot open trace: [Errno 2] No such file or directory: 'babeltrace'

I'll add the dependency check at installation, thanks for reporting.

Ideally, in the long-run, one should only need the bindings and not the actual executable, as it's currently only being used as a workaround for limitations in the API exposed through the bindings.
