debugging

问题 I have been trying to debug Remote Procedure Calls for WAMP (Web Application Messaging Protocol) based python components. For example: Front end (browser) session.call('math.add2', [2, 'two']); Back end (python) @wamp.register("math.add2") def add2(self, x, y): return x + y It gives a little bit of idea about the error. For a simple example like this, it doesn't really matter at all but for large applications with a lot of files and modules, Im not quite sure about the best way to pin point

问题 I am trying to run a C++ project in Eclipse Neon (on Linux) in debug mode and I am getting a weird error I can find no reference to. This is what I see in the console after right clicking Debug As >> Local C/C++ Application: &"Cannot exec -c exec /correct/path/to/executable .\n" &"Error: No such file or directory\n" The application otherwise builds and runs fine. I can right click and Run As >> Local C/C++ Application. What is causing this error? Edit: I have found out some more info which

问题 I am debugging a C project with Visual Studio 2013. What does the {???} mean in the below Watch window? I guess there must be something wrong and I searched a bit. But no luck. 回答1: Igor’s suggestion is correct, this is the sample for this issue. If I disable the line code “currnode->nextnode = NULL;”, it will show the same result as yours. But if I enable it, it would show the NULL value like this screen shot, so it would be related to null value of the pointer. 来源： https://stackoverflow.com

问题 I'm now studying library interpositioning with C in Ubuntu 18.04, and I'm testing two simple codes to wrap strlen : "mystrlen.c", "mystrlenTest.c". Here is the code I wrote: mystrlen.c #ifdef RUNTIME #define _GNU_SOURCE #include <stdio.h> #include <string.h> #include <dlfcn.h> /* strlen wrapper function */ size_t strlen(const char *str) { size_t (*strlenp)(const char *) = NULL; printf("%s\n", *str); strlenp = dlsym(RTLD_NEXT, "strlen"); // Get address of libc strlen printf("length: %ld\n",

问题 I have built a new development machine and installed Android SDK. I tried to obtain the Android MD5 debug fingerprint but cannot seem to get it to generate. I have deleted the debug.keystore to create a new one and only the SHA1 fingerprint is present.

问题 This may well prove to be a simple config change, but I can't seem to find an obvious setting to solve the following problem: I have a Vaadin project in Eclipse, which is configured to be debugged with Tomcat v6. If I select the top of the project in the project explorer and hit debug, the eclipse browser launches and my web app opens with the following url: http://localhost:8080/MyVaadinProject/ THIS WORKS However, if I'm currently looking at a java file (say Myproject.java), Eclipse tries

问题 I'm trying to enumerate tabs of IE from an extension and from a standalone application. For one of the MSAA nodes get_accChildCount returns 0 when called from extension, while it should return 1 according to inspect and a call from standalone application. The problem was described previously at StackOverflow, yet it was solved via a hack that doesn't work for me. /clr and /MT are incompatible. Also there was a topic on MSDN with the same issue. There's no single answer there. If you run IE

问题 I am attempting to debug a signed apk running on a real device... and when I say debug, I mean do things like add breakpoints and single step - I don't just mean view the log output. Looking at other similar questions it appears that I need to display the DDMS view and then somehow attach the debugger to the process, but I am confused for two reasons. I can not see a list of processes under my real device (though I do see a list of processes if I start up an emulator). [this bit now solved -
