Hello, I did the "Build and analyze" in xCode and get "Dereference of null pointer" when setting a normal int to 0 in my init-method. I noted in my code below for which row I get the message. I'm developing for iPhone. Bric.m #import "Bric.h" @implementation Bric - (id)initWithImage:(UIImage *)img:(NSString*)clr{ if (self = [su...
Hello, I am developing an iPhone app and are using xCode to do "Build and analyze". I get the message "Receiver in expresseion is a garbage value" pointing to the line of the return-row in my bode below: -(UIColor*)getLevelColor{ UIColor* tempCol; if (level==4) { tempCol= [[UIColor alloc] initWithRed:0.39f green:0.82f blue:0.32f ...
In Visual Studio 2005 and 2008, the Autos Window displayed all the variables on the current line being debugged as well as the three preceding lines and the three lines after the current. However, in Visual Studio 2010, the Autos Window displays variables on the current line and one line above and below only. Does anyone know how to ge...
for eg : var func:Fuction = function ():void { var i:int = 0; return i; }; Is there a way by which I can print the contents of the variable func at run time? By contents I mean the function body. ...
When I set up a breakpoint, it works, but when I try to step to next line of code, it leaves the debug mode (as though I clicked continue button). ...
Hi. Is there a way to define/undefine debug messages using std::cout whenever inside a program? I am aware that there are such things such as #define, #ifndef, but I was thinking is there a cleaner way to having a variable say: # debug ON That prints all of my debug data (using std::cout). Consequently, we'll have code like this fo...
I would like to learn how to make a text editor using GTK+. I think the best way to do this is to watch what is happening in the code when one runs Gedit. I have been told that one has to compile the sources of Gedit and GTK+ for -g option. But as I am a very beginner of open source world, I would like to know How can I load the sourc...
I have some code that is crashing in a large system. However, the code essentially boils down to the following pseudo-code. I've removed much of the detail, as I have tried to boil this down to the bare bones; I don't think this misses anything crucial though. // in a DLL: #ifdef _DLL #define DLLEXP __declspec(dllexport) #else #define ...
Ok this is a really weird problem. I wanna start off by saying that I'm not a beginner in c++ and I'm certainly not advanced. I'm somewhere in the middle. What I'm trying to do is make a C++ OOP wrapper library (dll) of the Win32 API. Here are the classes of my library. I compiled it with Mingw using the command: g++ -shared -o bin\win3...
IF I am testing something related to an error, I might want to see the message or stack trace in the console initially. After I'm satisfied with the test I typically do not want to have the console cluttered with anything that might help quickly spot and diagnose a failing test. When refactoring though, it is sometimes useful to once aga...
I have a file with 13.4K LOC. I would like to set a breakpoint that will be hit if any of the methods in the file are called. Is this possible? (Going through and marking them all myself would be a huge pain.) ...
any pointers on what must not be in an awk script? I am asking as I dont find any tool to debug an awk script. I have a script taking a lot of cpu so need to know if I am doing something terribly wrong with the script. Just for an example, I keep looking for output of a logfile via 'tail -f filename' till my script gets killed. ...
When I try to build my project I get the following error. ld: duplicate symbol .objc_class_name_GLFunView in /Users/gin/Documents/development/GLFun/build/GLFun.build/Debug-iphonesimulator/GLFun.build/Objects-normal/i386/GLFunView-7A51E8797CBB3D72.o and /Users/gin/Documents/development/GLFun/build/GLFun.build/Debug-iphonesimul...
i'm working on a CF project for a while now, and the VS started to behave starnge for me at least. I observed that when I start debugging, it builds the project, it's starting the deloy, the deploy finishes and it's starting to load symbols for my project. But it is very slow, and I don't know why it started to do this step. I have no ...
Am running Eclipse Build id: 20100218-1602 with Pydev 1.60. My code executes under python and jython, and also debugs fine under python. But when I try to debug under jython I get the message pydev debugger: starting --and then everything hangs. It looks like a couple processes are running in the debug screen but no code is display...
I'm following a tutorial from chapter 12 of the book "Beginning iPhone 3 Development." When I try to build the project I get an error. The book came with the project files, so I went through every file in my Classes directory and copied and pasted the code from the example project so that they are identical. This has solved my build erro...
What is the best way to hack away a bug in GTK+? The bug in https://bugzilla.gnome.org/show_bug.cgi?id=127840 is irritating and I would like to see a working version of it. But there is just so many lines of code so how can I find the correct part of the code? I'm using DDD. ...
The following program compiles with g++ but then crashes upon running: class someClass { public: int const mem; someClass(int arg):mem(arg){} }; int main() { int arg = 0; someClass ob(arg); float* sample; *sample = (float)1; return 0; } The following program does not crash: int main() { float* samp...
I am having some problems with a given test, that I'd like to debug the code that is being tested, while the test runs. Is this possible? If yes, how can I just debug this one test? I can only see options for running or the whole solution, or the whole set of tests in the current context or all impacted tests. I'd like to just run thi...
My application uses GLUTesselator to tesselate complex concave polygons. It randomly crashes when I run the plain release exe, but it never crashes if I do start debugging in VS. I found this right here which is basically my problem: The multi-thread debug CRT (/MTd) masks the problem, because, like Windows does with processes sp...
