This is a Continuous Cscope index updater.
CCscope depends on pficommon. Install pficommon and type
$ ./configure $ make $ sudo make install
At first, create a target source list "cscope.files".
example) $ cd path_to_project_dir $ find . -name "*.[ch]pp" | sort > cscope.files
Next, create an index updating script "cscope.sh".
example) $ emacs ccsope.sh +#!/bin/sh +cscope -b -q
Run.
$ ccscope
If you modify any file in "cscope.files", Cscope index is automatically updated. If you modify "cscope.files" itself, "cscope.files" is automatically reloaded too.
