[lttng-dev] compile error in lttng-ust-2.4.4

[Mathieu Desnoyers]

Hi,

This is a known issue with gcc 4.1, see:
https://bugs.lttng.org/issues/236

Normally, the configure check should have detected that your
compiler has issues with weak symbols. Not sure why this check
did not trigger in your case, but clearly your compiler is
clearly not supported. You will need to upgrade your compiler.

Thanks,

Mathieu
