Recently (I suspect some system/homebrew update) the Qt's debugger stopped working. It hangs forever on Setting up inferior...

I've found a nice plugin for lldb that allows watching memory regions as images: https://github.com/carlodalmutto/ImageWatchLLDB As I can see, this plugin was developed for Xcode and not for Android. However, it is written in Python and therefore should be cross-platform. I've found a directory c:\Users\username\.lldb\ on my hard drive. Its size is about 1 Gb. I've created following files: c:\Users\username\.lldbinit , c:\Users\username\lldbinit , c:\Users\username\.lldb\lldbinit , c:\Users\username\.lldb\.lldbinit , c:\Users\username\.lldb\init All of them have the similar content: script

I have a large-ish C/C++/Objective-C project building for OS X in Xcode. The project links to pre-built Qt5 libraries. That all works very nicely, until something crashes and I get a stack trace with Qt functions in it. If I click on the stack frame for one of the Qt functions, Xcode/lldb displays assembly rather than source - I'm using Qt as an external library, so I don't have any of the Qt source in my project. How can I fix this? I've tried adding the Qt5 source to the project without adding it to my executable target, but Xcode/lldb still doesn't 'see' the source or figure out that the

Is there a way to tell LLDB to ignore a file, i.e. step over code in that file when debugging? (This could be used as a workaround for 1 , 2 , 3 ) There is a setting to avoid stepping into functions whose name match a regular expression, (lldb) set list target.process.thread.step-avoid-regexp step-avoid-regexp -- A regular expression defining functions step-in won't stop in. e.g. put this in your ~/.lldbinit file settings set target.process.thread.step-avoid-regexp ^[^ ]+ std::|^std:: but in Xcode 4.5.x that's the best that can be done. I mentioned in #2 of your links that inlined stepping
