bson only c++ library?

[sptrakesh]

Hello,

Is there any way to build a pure bson library from the sources? A
brief look at the bson sources does not look very promising (includes
from other sections). I would have liked to build a static c++ bson
library from use from a iOS application. I supposed, sticking with
JSON is the only option at present. Any plans on decoupling the bson
implementation from the mongodb sources?

Thanks

Have you tried building the C++ drivers?
How close are they to what you need?

The C++ drivers should include BSON, but will exclude a lot of the
other core code.
Looking at the includes, a lot of them seem to be "utils". Are those
utils too dependent?

I do not need the client driver itself, just the ability to consume
bson data.

I have not looked too far, but just the first file in the bson
directory bson_db.h included ../util/optime.h which in turn includes
db/concurrency.h.

I shall try and pull out the sources and try building to see how far I
get.

you should just need to include bson.h or jsobj.h. bson_db.h is
internal to mongodb hence the namespace is mongo instead of bson.

I copied over the required files and created an Xcode Cocoa Touch
Static library project, and after a bit of hacking got the sources to
compile. I need to write a unit test suite to ensure that the
compiled library works properly. Once that is done, I shall make the
library project sources available to any one who is interested.

I have uploaded a cocoa touch static library project with some simple
unit tests to http://sptci.com/uploads/mongodb/bson.zip. I have not
tested on a device yet, but the tests run on the simulator.

If you can confirm this works on the device, please let us know and we can include this link somewhere in our driver docs.

Yes, it does work on the device (iPhone 4 running 4.2). I have
updated the zip file to contain the simple test application as well.
I have also attempted to document the main changes we had to make to
the sources at http://sptci.com/docs/ios/bson/

Have/had you considered using the c bson library instead of c++?

No, the Magnolia documentation indicated a preference for the C++
library over the C library, hence the decision to stick with it. I am
also more familiar with the C++ API, since I have used it before.
There will also be some code reuse for the iOS app being built, which
again requires the C++ API.
