CEDET Cache Error

Question

When emacs starts up, CEDET complains about a series of cache files being write protected:

Cache Error: [~/.semanticdb/!usr!include!i386-linux-gnu!sys!semantic.cache] (error In save file, list of object constructors found, but no :type specified for slot :tables), Restart Note: file is write protected [2 times]

And when I call semantic-ia-complete-symbol-menu for the first time, a load of cache errors are thrown and the minibuffer goes crazy with error messages for a few seconds.

Cache Error: [~/.semanticdb/!usr!include!i386-linux-gnu!gnu!semantic.cache] (error In save file, list of object constructors found, but no :type specified for slot :tables), Restart [8 times]

After the initial call, the problems go away.

Answer 1

Exit emacs, remove ~/.semanticdb & start again - the directory will be recreated & files will be reparsed. It looks like, you run emacs as root.

Or you can simply change permissions with chown -R <your id> ~/.semanticdb and chmod -R a-w,u+wr ~/.semanticdb
