<div dir="ltr">Hi,<div>I have a wrapper app which is 32-bit which is similar to lttng binary, it links to liblttng-ctl for creating lttng sessions (similar to lttng) . But the session create is stuck with below logs.</div><div><br></div><div>To simulate this i have done following</div><div>1) On a 64-bit system replace /usr/bin/lttng with a 32-bit version of lttng binary</div><div>2) Spawn lttng-sessiond (sessiond is 64-bit, we have not changed it)</div><div>3) Now create lttng session using the 32-bit lttng binary using command "lttng -vvv --no-sessiond create mysession --live 2000000 -U net://localhost"</div><div><br></div><div>After step 3, the console is stuck and doesn't return.</div><div><br></div><div>Can anyone please tell me why cant we use 32-bit lttng (or any other wrapper) which can link to liblttng-ctl and launch sessions? is there any limitation?</div><div><br></div><div>Thanks,</div><div>Anand Neeli</div>
