lldb

问题 This is by far the strangest thing thats happened to me. So I have the code below in a unit test... let aStoryboard = UIStoryboard(name: "myStoryboard", bundle: nil) let viewController = aStoryboard.instantiateViewControllerWithIdentifier("myViewController") as? CustomViewController The code above is executed and viewController is nil, okay that can happen (it shouldn't be because both identifiers exist and files are linked to test targets) but yeah okay. Here's the crazy part, when I add a

问题 I'm trying to debug a C++ OS X application in XCode 5.1 (5B130a) under OS X 10.9.2. The application is composed of various library projects that get compiled into libraries and used in a main application project. I set a breakpoint in my code and when I run in lldb: expr 2 this is what I get: (lldb) expr 2 error: field '__f_' declared with incompatible types in different translation units ('__base *' (aka 'std::__1::__function::__base<void (std::__1::shared_ptr<const XXX>, const YYY &)> *')

问题 I have some troubles getting lldb to show me a correct string output in my CEF FileHandler When I debug this application built with clang-5.0.1 (llvm install with brew) with the debugger lldb: [ 96%] Building CXX object gui/executionGraphGui/CMakeFiles/ExecutionGraphGUI.dir/cefapp/FileSchemeHandlerFactory.cpp.o /usr/local/opt/llvm/bin/clang++ -I/Users/gabrielnuetzi/Desktop/ExecutionGraph/gui/executionGraphGui -I/Users/gabrielnuetzi/Desktop/ExecutionGraph/include -I/Users/gabrielnuetzi/Desktop

问题 I am trying to find a way to display the values in arrays in my ojective-C based iphone program, as described in my other question here I am able to get the contents of an array in my program into the python interpreter while the iphone program is stopped at a break point inside a function (to be specific, the function is the render callback function for audio) However, when I tried to plot the contents of the array (availabe as SBValueList in the Python interpreter) using matplotlib, the

问题 XCode comes with LLDB, presumably there is a way to enable it as the debugger to use when debugging XCode projects. Of course being a Linux user I have become a hardcore command-line fanatic and I have a well-established Vim and Tmux workflow. Also being a code portability freak, 100% of my scripts work on both OS X and Linux. So is there some sort of way to "Pull out" the LLDB from deep within the bowels of XCode and run it from the command line? What are the benefits of compiling it

问题 Just finished updating codebase to Swift 4. It is working fine in the simulator. When I build to a device I get an instant crash with no error message: It works fine in the simulator. There are some threads on it: App crashes only with (lldb)? iOS app crashes with no error, just (lldb) dyld`__abort_with_payload: With no error message From what I learned the problem might be linked binaries but I've dug into my linked binaries and I believe everything is linked correctly. Any thoughts on where

问题 I have recently encountered a really weird problem while debugging C/C++ application in Android Studio.

问题 I seem to have trouble getting lldb to run. I'm on a Ubuntu 14.04 system and downloaded lldb-4.0 via apt. (lldb) target create dbgme Current executable set to 'dbgme' (x86_64). (lldb) process launch error: process launch failed: Lost debug server connection I don't want to do any remote debugging. Just local debugging. Do I need to start the lldb-server either way? And if so how do I do that? 来源： https://stackoverflow.com/questions/41232160/lldb-process-launch-failed-lost-debug-server

问题 I updated my Xcode yesterday. Now I cannot debug code in Qt, as it is always stuck "running". I'm using LLDB on Mac OS X 10.10.5 and Xcode 7.0. 来源： https://stackoverflow.com/questions/32642832/qt-debugger-stuck-when-running-on-mac
