Since I like to have fancy cheat sheets, I created one from the GDB to LLDB Command Map.

Just like in my previous post I need to jot down some useful commands for Lldb because I need to look them up so often. It contains standard breakpoint handling and running - just the very simple basics I should never forget. Note that this document will grow over time, hopefully.

First of all, do not forget to prepend xcrun to lldb, that makes it much more useable:

Since I happen to forget this every once in a while and end up in trying to debug in the command line but no symbols and no source is found, I drop a message for my future me:

Today I installed clang_complete using Pathogen (i. e., I installed it as a submodule of my dotfiles git repository aka nesono-bin. I tried to be smart and went into the submodule’s directory and invoked make install. That nicely built the vimball and installed itself - but whenever I tried to open a cpp-file I got the following error:

What a bad surprise, trying to build the Makefile-based project and got the response: make not found!
Lucky for us, it has just moved into the XCode package - the logical place according to Apple’s rules, though not automatically in the PATH environment variable :/

Some time ago, I wanted to x-out all constant C-strings (characters within ") in a C-file and wondered how to do that with Vim. E. g. when you want to cross out every character of a Hello World String like this:

Since ever, I was searching for a solution for nice C++-aware code navigation for vim. The solution described here is based on

• ctags
• omnicppcomplete

Just install the omnicppcomplete plugin in vim and call ctags.

Today I wanted to get all macro definitions from gcc - including those defined internally. I knew it some tim ago, but forgot the command again, so I paste it in here for all of you.

gcc -dM -E - < /dev/null | sort

That’s it and cheers,

Yesterday I stumbled over a problem using XCode 3. I was caused by a library, which was based on plain Makefiles. I tried to use this library in my XCode project, but anyhow, I always got the same error while linking.

Yesterday I found a site called The Bit Twiddler while searching for an algorithm to calculate the bit population of an int in C. To me, it was quite like breaking a butterfly on the wheel, but it was very interesting and good to know for everybody who needs to twiddle with bits… But check it out yourself!

Cheers, iss.
