Social networking APIs and C/C++ - c++

Folks,
Note sure if this is the best place to ask this one, but I doubt there'd be a better place. I see that github, stackoverflow, facebook, twitter, linkedin etc. have been providing developer API to slice and dice user information. Couple of questions on the general nature of these API:
1) Are these open-source?
2) Is there any general feedback on which specific programming language works best with these kind of 'social' APIs? In particular, any comments on whether C/C++ are suited for such work?
3) Is there any recommended C/C++ open source package for 'mashups' across social networks?


An API is a specification, not code, to "open-source" doesn't really apply though each might have licensing restrictions on how you use their API that might affect how suitable they were to your code being open-source.
The language will be dictated (or suggested) primarily based on what you're doing with the data, not how/where you obtain the data. You might find the networking part a bit simpler with something like Python or Perl, and do only the heavy computation (if any) in C++.
I doubt there's one that's universally recommended. The usual suspects (e.g., Boost::ASIO, ACE, POCO) will probably work reasonably well for this as they do with other networking.


Most of the social networking sites provides RESTful API that means that you need to send/receive HTTP requests/response from your application with the supported serialization format (XML/JSON/etc). Pretty much thats all you need to do. Any good Networking library and serialization/de-serialization library would let you call the APIs provided by the social networking sites. Ruby/Python/Java/Google Go/Scala has good support for these libraries/techniques. As for C++ Boost and Poco Provides rich set of networking/serialization libraries. Here is a facebook client library in C++. For twitter you have QTweetLib , QTwitLib and twttcurl. The social apis are kind of web services provided by these sites. I am not sure if opensource really applies to them.

SOAP alone is for compatability and with WSRF for stateful communications?

I know this might be a very basic question but I read so many articles on SOAP and I need to make sure I got it right.
In brief, I use SOAP because it's build on XML and thus I can have a standarized way to enable compatible communications between incompatible systems (in terms of OSs, architectures, programming languages, APIs, ...).
But still SOAP is statelss. And so to make it stateful, SOAP needs to be used along with WSRF (Web Service Resource Framework).
Qustion: Is my basic understanding right? Kindly correct me or illustrate more.

using iRODS c++ API

I intend to put/get file to/from an iRODS server. iRODS provides well documented JAVA and PHP APIs, however I'm looking for a C/C++ library providing such functions.
Are there libraries or examples of code I could use ?

Not exactly what you've requested, but you might be interested in Baton, which uses the iRODS C API, and has had a lot of work put into it, so you might be able to use it as-is, depending on your use case, rather than writing your own from scratch. Failing that, it provides a lot of examples of using the API.
If you have reasons that you must write your own, then in 4.x the the iRODS docs for the C API are much improved from the earlier 3.3.1 code path.
Good luck and do try the mailing list as a previous commenter mentioned - the developers respond often.

C++ Soap Toolkits

I am looking for a SOAP toolkit which I can use with C++ language on Linux system.I have taken a look at AXIS2C and i find it poorly documented. gSoap unfortunately requires a license, so are there any others which are out there?

The only SOAP toolkit that I've used for C++ is QtSoap which is fairly low level, only supports SOAP 1.1, and is Qt specific.
gSOAP can be used commercially without a license inasmuch as you aren't using the wsdl2h binary and associated generated code.
There are a number of others that you could investigate.
Also any other approaches to achive the same (consume web services) would be appreciated.. As of now i understand that only way out is via a toolkit
Since most web services are "just" XML, you don't need much in the way of a supporting library if you're willing to work through some of the protocol requirements. If your needs are simple, this may be sufficient.
Another option is to use bindings to Java or .NET where plenty of supporting libraries are available.

What is the C version of RMI

I have a set of functions in C/C++ that I need to be available to accept calls and return values to C/C++ code in a remote location, similar to RMI on the java platform. With RMI the Java methods are set up through the rmiregistry and remain available in memory to accept requests. I'm looking for similar functionality in C/C++, but i'm a bit confused with all the options that are out there. Is this type of scenario that CORBA was intended for and if so, is this still the best technology to use or are there better options out there. I've read about XML-RPC, CORBA, and a few others but i'm not sure which of these is what i need.
Thanks for your help.

Is this type of scenario that CORBA was intended for and if so, is this still the best technology to use or are there better options out there.
Yes, this is what CORBA was intended to solve. Whether it's "best" is subjective and argumentative. :) I can say, from my personal experience, I don't miss my short experience with CORBA and would suggest you explore other options.
I've read about XML-RPC, CORBA, and a few others but i'm not sure which of these is what i need.
As you seem to be aware, you're looking for any technology that implements RMI (also frequently called RPC). It's not built-in to C/C++.
On Linux, there is SunRPC. I would also recommend looking at Google protocol buffers, which provide a mechanism for serializing data as well as an interface for defining RPC services. There are several service implementations available, but I don't have experience with the service implementations.

On Unix-like platforms, you're probably looking for Sun RPC (remote procedure calls).
CORBA is also relevant but has a more natural binding to languages with object oriented capability.

There's no built in method for accomplishing this in C or C++. That said there are several libraries that can accomplish this.
If you're on Windows, then the best answer is probably DCOM, which is part of the OS itself. I'm not sure about other platforms.

I shall suggest either CORBA or any webservice library available
CORBA is a reasonable choice for you (though it may be a little bit old technology for now). I have been using CORBA for several years in my previous job.
I should say, learning curve for CORBA is kind of steep, and you need to cater a lot of extra setup, but once it it done correct, it become smooth to use. (The problem is it takes really some time to use it correctly)
Webservice is an de facto industrial standard now, and I believe C++ will have some reasonable implementation and library for that. CORBA cover more features than WS but those feature are seldom used in simple systems.

I've been looking around and came across the WT toolkit, Is it stable? Any good?
I was stumped on how to go about this in C++, given the lack of libraries and resources concerning web developement. (CGI/Apache)
The purpose of my application is to populate some data from a Sybase ASE15 database running GNU/Linux & Apache Hence allow some user interactions.
I am going to use Sybase open client library (libct) to retrieve columns from the Server, feed this data back to wt model/view.
My requests:
Is there any more practical solution rather than using other scripting languages?
I mean by practical, an interface with ODBC retrieving, and MVC mechanism?
If not available in C++, any alternative in Java?

C++ isn't a very popular choice for
web applications - probably because
it's too easy to leave security holes,
and development time tends to be a lot
slower than for the scripting
languages.
Dynamically typed scripting languages convert compile-time errors to runtime errors. Detecting those might not be as easy as reading through the compiler output. Scripting languages may be OK for quick-and-dirty simple projects. Beyond a certain level of complexity one needs strongly typed, well-structured languages. Such as C++, or Java.
Most scripting languages encourage sloppy programming.
As to the "security holes": if you refer to buffer overruns, allocation/deallocation errors, the answer is "STL". And proper training of course :-)

http://cppcms.sourceforge.net/wikipp/en/page/main
C++ web service framework
For starters. There are certainly more I'm sure - a healthy google search probably wouldn't hurt. Also, you could try the #C++ channel on freenode - they have an offtopic channel that you can ask about if you want to talk about non STL C++ and the people there would happily answer your questions I'm sure. Good Luck.

tntnet (http://www.tntnet.org) is great for creating web applications with C++.

Give this one a look. I never much liked Wt's design. But then, I'm kind of an anti-framework guy.

CGI programs are pretty damn easy to write in both C and C++ - you don't really need any special library, though having one will obviously make development a little faster. Do you really understand how CGI works? Basically, your program reads environment variables with getenv(), does some processing, and then writes some HTML out to the program's standard output.

Basically, it's a framework AND server that makes writing C++ web backends easy...

The best web toolkit for C/C++ would be Apache httpd. Just write a module and you can use libct to access your database.
There is MVC modules out there like mod_spin but I don't have any experience with it.

C++ isn't a very popular choice for web applications - probably because it's too easy
to leave security holes, and development time tends to be a lot slower than for the
scripting languages. I'd say 99% of web applications don't need the speed that
C++ brings.
So this leads to a lack of good frameworks.
From my fairly light look at the area I'd say Wt is probably your best bet, although
it's more of a library of useful things (like page templates) than a framework.
I'd seriously consider not doing this in C++ though. Even Java (I prefer C++ myself) has
much stronger support for web development.

Another alternative may be the "FastCGI / CGI C++ Library" that is aimed for Boost integration at someday: http://cgi.sourceforge.net/

Qt is going to grow day by day. And Wt is the trying to stand for web tool kit based on Qt. C++ the powerful language and the best in my opinion. If you like gnu projects and independent tech. I really suggest to use them. I used PHP, Phyton, C#, VisualBasic, Fortran etc. but I did not like as much as C++ among of them.

I gave Wt a try and really liked it. I will not give you any cons or pros for using it from scratch, but when you have a backend written in C/C++ with millions of API entries then Wt is an obvious choice. There are some very powerful features that is easier to use for example dynamically loaded tables. Signal processing on the server etc.
One thing I really disliked at Wt is that it is not compatible with Apache on Windows as of time of this writing. You either have to use Unix, or IIS on Windows. Wt also offers its own http server, that is very convenient for developing your applications but I would not trust it in the role of production server as I am not sure of its security.

My personal choice for web development is Ruby on Rails, but if you have to chose between C, C++ or Java for web development, my suggestion is to use Java with JavaServer Faces

Apache Celix looks like a promising active project that meets the requirements of this (albeit old) question. See: http://celix.apache.org/
From the Apache Project description page:
Celix is an implementation of the OSGi specification adapted to C. It will follow the API as close as possible, but since the OSGi specification is written primarily for Java, there will be differences (Java is OO, C is procedural). An important aspect of the implementation is interoperability between Java and C. This interoperability is achieved by porting and implementing the Remote Services specification in Celix.
