the vim cscope easy tutorial

The following steps to help you to set up cscope easily.

1. install cscope:

user@ubuntu-64bit:~$ sudo apt-get install cscope

2. Download the cscope_maps.vim file, put it to $HOME/.vim/plugin directory:

user@ubuntu-64bit:~$ mv Desktop/cscope_maps.vim .vim/plugin/  

3. Try setting the $CSCOPE_DB environment variable to point to a Cscope database you create:

    find /my/project/dir -name '*.c' -o -name '*.h' > /foo/cscope.files

   Then run Cscope in the same directory as the cscope.files file (or use 'cscope -i /foo/cscope.files'), then set and export the $CSCOPE_DB variable, pointing it to            the cscope.out file that results):

    cd /foo
    cscope -b 

    CSCOPE_DB=/foo/cscope.out; export CSCOPE_DB

    " 'i' includes: find files that include the filename under cursor

    " 'd' called: find functions that function under cursor calls
