I'm not sure about the garbage characters, but the missing prompt is usually due to a bug in the version of libedit shipping with common Linux distributions.
http://llvm.org/bugs/show_bug.cgi?id=14637 The latest libedit has that fixed, so you could give that a shot. -- Stefanus Du Toit <[email protected]> Intel Waterloo From: Zack Perry <[email protected]<mailto:[email protected]>> Reply-To: Zack Perry <[email protected]<mailto:[email protected]>> Date: Thursday, 15 August, 2013 2:48 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [lldb-dev] lldb built with self-hosted clang toolchain issues garbage output on quitting I just built lldb 3.3 (with the official release tar ball) using a self-hosted clang toolchain (built with libc++abi and libc++ too. No libstdc++ dependency whatsoever) The box runs Ubuntu 12.04 64bit with the latest updates. Upon launching it after make install, the first help displayed correct message. Then no prompt and a quit command generated a lot garbage characters ;-( Is there a way to get around this issue? I really would love to try the lldb built with a pure clang tool-chain. -- Zack zackp@nb1:~/Downloads/clang3.3/build$ lldb (lldb) helpThe following is a list of built-in, permanent debugger commands: _regexp-attach -- Attach to a process id if in decimal, otherwise treat the argument as a process name to attach to. _regexp-break -- Set a breakpoint using a regular expression to specify the location, where <linenum> is in decimal and <address> is in hex. _regexp-bt -- Show a backtrace.
