Use vim to open the line from gdb (or gcc err output)
This might be kind of specific. But...
We've all been there. There's a backtrace as long as a CVS receipt in your gdb window.
mkdir -p ~/.vim/plugin wget -O ~/.vim/plugin/file_line.vim https://raw.githubusercontent.com/bogado/file-line/master/plugin/file_line.vim
And now you can:
like a boss.
