lldb

I'm tracing a OS X application, I hope can find a way like this way on iOS: lldb Xcode: error: 'printf' is not a valid command Is there a way to do like this? I tried expr -- (void)printf("[%s, %s]\n",(char *) object_getClassName(*(long*)($esp+4)), (char *) *(long *)($esp+8) ) I think OS X is used 64bit registers. So this command cann't work(Indeed, it doesn't work). How should I write this command? Or there is a simple way to do the same? Just tracing the class and method called The command you quote above is only correct for iOS Simulator apps which run as i386 processes on the Mac. $esp+4

Android Studio doesn't stop at breakpoints in C++ code, this is what i've done so far : In AndroidManifest.xml : android:debuggable="true" In build.gradle (this may be the problem): sourceSets.main { jniLibs.srcDir 'src/main/libs' jni.srcDirs = [] } task ndkBuild(type: Exec) { commandLine android.ndkDirectory.getAbsolutePath() + '\\' + 'ndk-build.cmd', '-C', file('src/main/jni').absolutePath, 'NDK_DEBUG=1' } tasks.withType(JavaCompile) { compileTask -> compileTask.dependsOn ndkBuild } Configured the application as a native application on Android Studio Put breakpoints in C++ code Debug the app

I'm working on a patch for FFmpeg and need to debug my code. I'm loading an external library, and in order to test different library versions, I have them in different folders. To select which one I want to use, I've been using DYLD_LIBRARY_PATH=/path/to/lib/dir ./ffmpeg and that works okay. But when I try it within lldb , it crashes saying dyld: Library not loaded and Reason: image not found . This used to work pre-Xcode 7.1, but I just recently upgraded and it stopped working. Here's my MVCE: #include <stdio.h> #include <stdlib.h> int main() { char* str = getenv("DYLD_LIBRARY_PATH"); if (str

I've been struggling with an weird issue for some time now. When running my app with the iOS Simulator initially closed it launches correctly. But if I then run it again without closing the simulator it crashes and just prints (lldb) in the error log. If I then run it again (without closing the simulator) it launches correctly. And if I do the same again it crashes. So it seems to be every second time. It works when using a iOS device and I have a college with the exact same project who doesn't experience this problem in the iOS Simulator. What I've tried is cleaning, reset contents and

I am playing around with the map kit and I created an annotation. I am trying to find my bug due to this error: An instance 0x1b7ac0 of class AddressAnnotation was deallocated while key value observers were still registered with it. Observation info was leaked, and may even become mistakenly attached to some other object. Set a breakpoint on NSKVODeallocateBreak to stop here in the debugger. Here's the current observation info: I'm not sure where that NSKVODeallocateBreak to set a breakpoint at is. I thought I could use Instruments to debug it, but when I try, it crashes without giving me any
