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.
