I'm running Ubuntu 8.04 and I ran the command:

$ ctags -R --c++-kinds=+p --fields=+iaS --extra=+q -f ~/.vim/tags/stdlibcpp /usr/include/c++/4.2.4/ to generate a ctags database for the standard C++ library and STL ( libstdc++ ) on my system for use with the OmniCppComplete vim script. This gave me a very reasonable 4MB tags file which seems to work fairly well.
However, when I ran the same command against the installed Boost headers:

$ ctags -R --c++-kinds=+p --fields=+iaS --extra=+q -f ~/.vim/tags/boost /usr/include/boost/ I ended up with a 1.4 GB tags file! I haven't tried it yet, but that seems likes it's going to be too large to be useful. Is there a way to get a slimmer, more usable tags file for my installed Boost headers?
Just as a note, libstdc++ includes TR1, which has allot of Boost libs in it. So there must be something weird going on for libstdc++ to come out with a 4 MB tags file and Boost to end up with a 1.4 GB tags file.
Just ran across this on the Boost mailing list:
Boost-users Boost and autocompletion
Thanks to Neg_EV for figuring out what the problem was, but there's a much better way of solving the problem than what he suggested:
Make sure apt-file is install, and run the following commands
( I keep my library tags in ~/.vim/tags/ ):

$ sudo apt-file update $ apt-file list boost | grep -E -o '/usr/include/.*\.(h|hpp)' | grep -v '/usr/include/boost/typeof/' > ~/.vim/tags/boost-filelist $ ctags --sort=foldcase --c++-kinds=+p --fields=+iaS --extra=+q -f ~/.vim/tags/boost -L ~/.vim/tags/boost-filelist I've upgraded to Ubuntu 10.04 and Boost 1.40 and that's what I tested this solution on, but it should work with any Boost version as far as I can tell.
