lldb

Environment: Mac/Mojave and GDB 8.2.1 (via homebrew). I worked through instructions https://forward-in-code.blogspot.com/2018/11/mojave-vs-gdb.html i.e.: latest GDB via brew, which solves the executable format issue sign GDB with new entitlements Additionally, I've also modified SIP to allow debugging (in Recovery OS terminal: csrutil enable --without debug ). However, I still can’t get gdb to work: (gdb) file main Reading symbols from main...done. (gdb) run Starting program: /Users/joubertold/code/Rhodus/obj/debug/main [New Thread 0x1a03 of process 5082] [New Thread 0x2803 of process 5082]

I am trying to debug a C++ program I am writing, but when I run it in LLDB and stop the program, it only shows me the assembler, not the original source. e.g. after the crash I’m trying to debug: Process 86122 stopped * thread #13: tid = 0x142181, 0x0000000100006ec1 debug_build`game::update() + 10961, stop reason = EXC_BAD_ACCESS (code=EXC_I386_GPFLT) frame #0: 0x0000000100006ec1 debug_build`game::update() + 10961 debug_build`game::update: -> 0x100006ec1 <+10961>: movq (%rdx), %rdx 0x100006ec4 <+10964>: movq %rax, -0xb28(%rbp) 0x100006ecb <+10971>: movq -0x1130(%rbp), %rax 0x100006ed2 <+10978>

What is the difference between GDB & LLDB debuggers? I recently upgraded my Xcode version from 4.2 to 4.3 & started getting warning to upgrade my debugger from GDB to LLDB. infinitetape LLDB is part of the LLVM suite of tools that Apple is moving to, including Clang. There are tons of improved features, including improved performance. There's a quick intro for GDB users here: http://lldb.llvm.org/tutorial.html However... You might want to take a trip over to the forums at developer.apple.com. There's a fair bit of rumbling about issues with LLDB at the moment (in XCode 4.3.1). One nasty issue,

I am currently writing an iOS app with Xcode 4.3.2. In most parts of my code, debugging with LLDB works just fine. However at some point I am getting a strange message while stepping through my code. When I hover over an iVar, it says Error [IRForTarget]: Couldn't find Objective-C indirect ivar symbol OBJC_IVAR_$_MyFancyClass.iVar instead of showing me the value. However, in the Variables View , I can see it just fine. Until I'm selecting Print Description of ... that is, because then, Xcode crashes... When I use GDB, the hovering works but the type and values of the variable are wrong. I

I'm getting this error whenever I build in XCode 6 beta 4. It seems to be making my app insanely slow. Warning: Error creating LLDB target at path '/***/***/***/***.app'- using an empty LLDB target which can cause slow memory reads from remote devices. What exactly does this mean and how do I fix it? Thanks in advance! khanhlvg Did you use Architectures=$(ARCHS_STANDARD_32_BIT) and run your app on a 64 bit device? (iPhone 5S or iPhone 5S simulator) Apple seems to be stricter with apps which don't support 64bit. So if there is no specific reason, I think it's better to include arm64 in your
