Does code completion work ? [message #160395]

I am a user of CDT for almost one year and I never saw the code completion
working. I thought it had something to do with the fact that I play with a
big library full of templates, something that is surely a bit confusing
for a code completion algorithm. Anyway, I just started to play with
single files and code completion seems always stuck...

Just to be sure, my file only contains these few lines :

struct A{
A(){;}
void pipo(){;}
}

A a;
a.

Then I press Ctrl+Space after the dot and eclipse says "no completion
available". Is this a normal behavior ?

CDT 3.0.1 / SDK 3.1.0, and my preferences
C/C++ --> editor --> Code Assist :
search curent file and includes
insert single
insert common
delay 3000
enable all
delay 1000

C/C++ --> indexer
Full C/C++ indexer (is this the problem ?)

It works for me (when I modify your code to be syntactically correct):

struct A{
A(){;}
void pipo(){;}
};

int main(int argc, char **argv) {
A a;
a.
}

I should have mentionned it : I also tried with a int main (void){ A a; a.
} structure.
Anyway, just to be sure I copy-pasted your sample code and the behavior is
the same :
a."Ctrl+space" is stuck
a.p"Ctrl+space" proposes me a long list starting with pipo() but
comprising strange things like pthread_attr_t or ptr_diff which are
templated types...
note also that changing the delcaration of a in the main :
{ B a;
a.p"ctrl+space"
}
still proposes me pipo() even if class B doe not provide that function...

By the way, what is not syntactically correct in the sample code I
previously posted ? It seems to me that it is correct (though discouraged)
to declare a global object of type A.

There were two errors: 1) missing semi-colon at the end of the struct
def'n and 2) the a. (or a.pipo()) in the sample makes no sense in a
global context (I always try to compile the code examples before
commenting on anything using the CDT parser -- it is fragile with
respect to invalid code)

a.<ctrl-space> gives me pipo and A

a.p<ctrl-space> gives me only pipo.

Try creating a new project with only this file in it. If you get
pthread_* methods, there is more to your project than this little example.

good advice

well... I created a new C++ project with only that file in it.
I still have no completion enabled.
as for the "pthread" things it seems to come from the only
include:#include<iostream> that I add on the first line of the file
(commenting it results in no completion at all, uncommenting it results on
5 completion proposals for a.p : 4 pthread_cleanupxxx() and one putc()

I precise :

a.p"ctrl+space" does nothing if #include<iostream> is commented and gives
5 results if it is not commented. Anyway, pipo() is never proposed.

p"ctrl+space" gives always a lot of things (the same lot of things wether
#include is commented or not), and pipo() is in it...
