[lldb-dev] LLDB-MI from Eclipse hangs

via lldb-dev lldb-dev at lists.llvm.org

Thanks Ted for your reply.
I tried the same command that eclipse uses manually from command prompt. It
hangs after same last command "-exec-continue --thread-group i1". Attached
is the lldb-mi sample at that time.

While debugging from Eclipse I am going to Run--> Debug Configurations-->
C/C++ Remote Applications--> <My Configuration> and then click on Debug
button. And then all the commands are executed by Eclipse automatically. I
do not see two different steps as attach and continue. So I am not sure how
to pass command "log enable gdb-remote packets". May be I am missing
something. Can you please help me here, so that I can get the required log
as suggested by you? Thanks.

Have a nice day!
