I added (require 'cedet-cscope) and the error just appeared one level
below:


Debugger entered--Lisp error: (void-function semanticdb-enable-cscope-databases)
  (semanticdb-enable-cscope-databases)
  (progn (semanticdb-enable-cscope-databases))
  (if (cedet-cscope-version-check t) (progn (semanticdb-enable-cscope-databases)))

that's some progress at least... I commented those lines and tried
again, created a helloworld.cpp file that looks like this:


#include <iostream>

struct test
{
  int foo;
  int foobar;
  int bar;
  char ch;
};

int main(int argc, char *argv[])
{
  test teststruct;
  teststruct.foo = 10;
  return 0;
}


but, nothing, just more errors[1] :(. company-semantic doesn't work with
any C++ file! :'(
I then compiled Emacs from its repository as you suggested (version
echoes: GNU Emacs 24.3.50.1 (x86_64-unknown-linux-gnu, GTK+ Version
3.10.6) of 2014-01-23 on abril ) and tried again, the same:


Idle Service Error semantic-idle-summary-idle-function: "#<buffer helloworld.cpp> - Wrong type argument: stringp, ((\"__THROW\" 0 nil nil))"


I think that I'm doing a bug report for this issue (to the CEDET
developers I guess?) :(
