powerdns + mongodb

Question

I was trying to compile the mongodbbackend module for powerdns but I'm stuck with this problem:

In file included from mongodbbackend.cc:18:
mongodbbackend.hh: At global scope:
mongodbbackend.hh:109: error: ISO C++ forbids declaration of ‘auto_ptr’ with no type
mongodbbackend.hh:109: error: expected unqualified-id before ‘<’ token
make[3]: *** [mongodbbackend.lo] Error 1
make[3]: Leaving directory `/root/pdns-3.0.1/modules/mongodbbackend'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/root/pdns-3.0.1/modules'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/pdns-3.0.1'
make: *** [all] Error 2

I tried to include files from mongodb 2.0.2 and 2.0.3. Here are the module sources: http://wiki.powerdns.com/trac/browser/trunk/pdns/modules/mongodbbackend

Any suggestions?

Are you sure this is where the errors start? No errors right above it, like "error: client/dbclient.h: No such file or directory" ? — Habbie, Feb 23 '12 at 06:16

The post from Ruben is my anonymous/non-account post. I didn't look at the formatting so the post is a little messed up.

The compiler error you have can be overcome by adding:

#include<memory>

And changing line 109 from:

auto_ptr<mongo::DBClientCursor> cursor;

to

std::auto_ptr<mongo::DBClientCursor> cursor;

This, however, causes other errors on my end (see http://pastebin.com/Wm60JCDu). It might work for you though :-)

It would be helpful if you provide more info about your environment (distro, what version of mangodb and the used mango driver).

Hi, thanks for the tip, that fixed the problem :) but other issues appeared: http://pastebin.com/ThRZ4pP1 i'm using debian squeeze with mongodb 2.0.2 – shoen Feb 23 '12 at 08:45
The issues i have are with debian squeeze and the out of the box mongodb. – cyclops Feb 23 '12 at 09:03
From the error you are getting, it seems it has to do with the version of Mongo. I don't know which version of mongodb the author of the mongodbbackend is intending to use. I suggest asking him about that. (see README in the mongodbbackend folder) – cyclops Feb 23 '12 at 09:09

The compile error you have can be overcome by adding:

#include<memory>

and changing

auto_ptr<mongo::DBClientCursor> cursor;

to

std::auto_ptr<mongo::DBClientCursor> cursor;

around line 108/109/110 in mangobackend.hh

It might work for you, but I think it is heavily depending on the mangodb-api you're using.

It would be helpfull if you provide more info around your environment (distro, version of mango, etc)

Can you try this patch?

It's in https://github.com/azlev/powerdns/commit/a402d8493e5610e139ea19a9ef700e26b2e6e35c
