Re: [lldb-dev] Does LLDB work on Ubuntu 14.04 x86_64?

[Pavel Labath via lldb-dev]

Hi,

thanks for the report. Lldb does indeed work on linux x86_64 (and
plenty more), but I think noone tests it with your given combination
of cmake flags. I've managed to reproduce your problem and fix it with
, but please give it a go to make sure
it works for you. If all goes well, we'll get this backported to the
3.8 branch.

cheers,
pl
