I have used customize-group on semantic to set global-semantic-idle-summary-mode to t. My .emacs has this entry in custom-set-variables : '(global-semantic-idle-summary-mode t).
However, on starting emacs and opening a C++ source file, I don't see the idle summary at point.
On disabling and re-enabling idle summary mode with two calls to M-x global-idle-summary-mode, the summary items start showing up.
How do I set this up correctly?
I also had this problem, then I updated it to latest bzr and the problem goes away. You can checkout the bzr version:
bzr checkout bzr://cedet.bzr.sourceforge.net/bzrroot/cedet/code/trunk cedet
cd cedet
make
cd contrib
make
Then load your Emacs with the new CEDET. You must load it at the very start of your init.el otherwise once the built-in CEDET is loaded, you won't be able to load the bzr version.
As for those global modes, they are actually minor modes and you have to enable it like this:
(add-to-list 'semantic-default-submodes 'global-semanticdb-minor-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-mru-bookmark-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-scheduler-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-summary-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-stickyfunc-mode)
(semantic-mode 1)
custom-set-variablescontains an additional reference to the required library. Maybe you need a(global-semantic-mode 1)in your init.el?global-semantic-mode. In thesemanticcustomization group, I see a bunch ofglobal-semantic-*_modes. That's where I enabledsummary-mode.semantic-mode. You could also try starting Emacs and doingC-h f global-semantic-idle-summary-mode. If it tells you that it's an autoloaded function, the problem is that the corresponding library is not loaded.semantic-mode. This is customizable as well and I have it set tot.
