[lldb-dev] How to debug LLDB server?

[Eugene Birukov via lldb-dev]

Thanks! 
 
A newbie question then: how to trigger LLDB_CONFIGURATION_DEBUG when I run cmake? I am sure that I built debug version, but packet timeout is still 1 to me.
 
(gdb) p m_packet_timeout
$1 = 1

> Most calls for lldb-server should use an instance variable GDBRemoteCommunication::m_packet_timeout which you could then modify. But this timeout you are talking about is the time that the expression can take when running. I would just bump these up temporarily while you are debugging to avoid the timeouts. Just don't check it in.

Say, InferiorCallPOSIX.cpp:74 sets hard-coded timeout to 500,000us, etc. These timeouts fire if I spend any time on breakpoint inside server and make debugging experience miserable. Is there any way to turn them all off?
