debugging

问题 In part of my program, I have the code: if(cameraName == L"AVT Prosilica GT2750") { mCamera = new camera_avtcam_ex_t(); } else if(cameraName == L"QImaging Retiga 2000R\\4000R") { mCamera = new camera_qcam_ex_t(); } When I have set up my program so that cameraName defaults to L"AVT Prosilica GT2750" (and my debugger will show this to be its value), it goes into the if statement and runs mCamera = new camera_avtcam_ex_t(); , but then when I step to the next executed line my debugger skips

问题 For debugging Matlab-MEX, which can be quite a hassle, it would be nice to have better assertion capabilities. Following this question about mex-assertions, it is possible to define a preprocessor makro, that throws an error to Matlab and prints a string (can mostly replace mxAssert , which unfortunately crashes Matlab2011b). #define myassert( isOK,astr ) ( (isOK) ? (void)0 : (void) mexErrMsgTxt(astr) ) It would be much nicer to print the file, line number and caller function, from where

问题 I have terrific bug "object was modified after being freed", so I tend to take valgrind. After successfull installation from their svn, doing little trick from here: http://landonf.bikemonkey.org/code/iphone/iPhone_Simulator_Valgrind.20081224.html and changing path to valgrind with my one, I get "Debugger terminated." with gdb log: [Session started at 2010-08-03 10:47:25 +0500.] GNU gdb 6.3.50-20050815 (Apple version gdb-1469) (Wed May 5 04:36:56 UTC 2010) Copyright 2004 Free Software

问题 I am working on a MEAN stack app with Angular 2 frontend. I have successfully used debug in the express app. However I am unable to cleanly import debug in app.components.ts or main.module.ts . Any idea on how to proceed? <script src="/node_modules/debug/debug.js"></script> Results in error: Uncaught ReferenceError: module is not defined <script>System.import('./node_modules/debug/debug.js');</script> Not good either: zone.js:101 GET http://localhost:8002/ms.js 404 (Not Found) Some dependency

问题 I think I'm just cloudy on how debugging works on a real device - is that how to go about it? I've been reading through Apple's docs on creating provisioning profiles for distribution, but I'm not finding any information for simply debugging my app, which is running on my device, through Xcode. Can someone point me in the right direction? Edit (2/19/09): I'm getting conflicting answers on whether or not I need to create an ad-hoc provisioning profile to debug my app. If I don't need to create

问题 I am able to use the cmd to run my nativescript project ( tns run android). I open the project in VSCode, and add the Configuration to debug it. I hit debug and it look like the debug try to run or something. (Look at the green bar under debug. However, nothing seem to run. I look at the debug console, nothing is print out. Please take a look at screenshot. Spent couple days on this issue and couldnt resolve it at all. VSCode Debug Issue 回答1: Thanks Nick Iliev, The problem actually is from

问题 I'm currently using Werkzeug together with django-extensions and I'm able to call the werkzeug debugger by raising an exception or making a false assertion. Is it possible to just set a breakpoint for werkzeug like import pdb; pdb.set_trace() does? 回答1: If you are using Apache/mod_wsgi, all you need to do is modify your .wsgi file to include: from werkzeug.debug import DebuggedApplication and application = get_wsgi_application() application = DebuggedApplication(application, evalex=True) Then

问题 I have a windows service which fails in Init() method and throws some exception , so only way for me to check what the error is by looking at the event log. I want to debug the windows service, but the problem is that i can attach debugger only when service is rnning, in my case it fails in Init() method only. Any idea ? 回答1: you can programatically attach the debugger as the first line in the function: Debugger.Launch (); after adding the using statement: using System.Diagnostics; 回答2: What
