LLDB crash

I'm trying to po an object in lldb and I get the following:(lldb) po fooerror: reference to 'foo' is ambiguouscandidate found by name lookup is 'foo'candidate found by name lookup is 'foo'I have seen references to this error back in Xcode 4.x but nothing recent. Is there a fix for this? I'm using Xcode Version 9.2 (9C40b) and ObjC.

I type in the terminal: lldb$ lldbTraceback (most recent call last): File <string>, line 1, in <module> File /Applications/Xcode.app/Contents/SharedFrameworks/LLDB.framework/Resources/Python/lldb/__init__.py, line 98, in <module> import sixImportError: No module named sixTraceback (most recent call last): File <string>, line 1, in <module>NameError: name 'run_one_line' is not definedTraceback (most recent call last): File <string>, line 1, in <module>NameError: name 'run_one_line' is not definedTraceback (most recent call last): File <string>, line 1, in <module>NameError: name 'run_one_line' is not definedTraceback (most recent call last): File <string>, line 1, in <module>NameError: name 'run_one_line' is not definedTraceback (most recent call last): File <string>, line 1, in <module>NameError: name 'run_one_line' is not definedTraceback (most recent call last): File <string>, line 1, in <module>NameE

I'm trying to use a technique we use on Linux to get a stack trace of a process that gets in trouble. We fork a debugger in batch mode in a child process to get the back trace of the parent. When I run this, lldb hangs in the attach to the parent process. And since lldb cannot attach to lldb, there's no way for me to see what's blocking lldb in the attach to the parent. Attached is a simple program that demonstrates the problem. Manually running lldb from a shell with the same arguments gets the stack trace. Is there some way around this hang? #include #include #include #include #include #include static void runChild(pid_t parent) { tconst char *lldb = /usr/bin/lldb; tconst char * args[8]; tchar pidstr[16]; tsnprintf(pidstr, sizeof(pidstr), %d, (int) parent); targs[0] = lldb; targs[1] = --no-lldbinit; targs[2] = --batch; targs[3] = -p; targs[4] = pidstr; targs[5] = --one-line; targs[6] = thread backtrace all; targs[7] = NULL; terrno

Here's a simple C++ program that echoes its arguments... #include int main(int argc, char* argv[]) { for (int i=0; i ./test arg1 #arg2 arg3 0 ./test 1 arg1 2 #arg2 3 arg3 Running under lldb gives this... > lldb ./test arg1 #arg2 arg3 (lldb) target create ./test Current executable set to '/Users/richard/Work/test' (arm64). (lldb) settings set -- target.run-args arg1 #arg2 arg3 (lldb) run Process 6138 launched: '/Users/richard/Work/test' (arm64) 0 /Users/richard/Work/test 1 arg1 Process 6138 exited with status = 0 (0x00000000) I get the same if I quote the arguments, or if I add them to the run line. Stepping into main() we see the argv and args values are as though we only had the first argument. If I quote the second argument and add an initial space #arg1 then it works. I first saw this on an M1 running Sequoia 13.1. It am now on OS 13.3. lldb --version lldb-1600.0.39.109 Apple Swift version 6.0.3 (swiftlang-6.0.3.1.10 clang-1600.0.30.1)

Has anyone has this error when trying to run a watchOS 2 app on a connected phone and watch:Warning: Error creating LLDB target at path '/Users/user/Library/Developer/Xcode/DerivedData/app-cuurdvsnbtcffcgnbrqkwlimkdjj/Build/Products/Debug-iphoneos/App WatchKit Extension.appex'- using an empty LLDB target which can cause slow memory reads from remote devices.Would love to know if there's a fix to this.

We are updating our macOS projects for Universal binaries and our two main apps fail to debug in Xcode 12.2 (on Big Sur), but I can use lldb from the command line to run the built app. When I try to run the app in the debugger in Xcode I get this error: Warning: Error creating LLDB target at path 'my app path'- using an empty LLDB target which can cause slow memory reads from remote devices. error: failed to launch '2687' -- LLDB provided no error string I assume the number is the PID, it changes each time I try to run the debugger. Not sure what to do.

hello, i can't fix this error displayed in the return line(lldb)int main(int argc, char *argv[]) { return UIApplicationMain(argc, argv, nil, NSStringFromClass([PoutremultivueAppDelegate class])); }
