Web Programming with C++

[Morph]

Is it possible to do ? If it's possible how ?

[korg]

You can use some type of SOAP tool kit to consume web services ......

CGI springs to mind:

Yes, you can use C/C++ to create CGI scripts. There are also a few libraries that make it easy to program in C/CGI. Check this book:

http://bookboon.com/int/student/it/c-programming-in-linux

It is free , like any Bookboon book, but there are a few advertisements.

The big drawnback with C/CGI is that doing the layout for XHTML pages is really a pain, but you can split your systems by having frontend pages written in .NET and C++ in the background.

I would consider the biggest drawback being that most web hosting packages will not let you run executable CGIs. Scripts, such as Perl and PHP dominate.

Google Native Client allows to run C programs directly on the client browser

[Morph]

I should explain what i want. Consider a c++ project and in this project lets say I want to use php. Let me give an example. I want to show my twitters last post in a program.

[Galik]

So you want to write a program in C++ that accesses a web-service written in PHP? Is that't what you are saying?

[Galik]

You might want to look at CURL for accessing web-resources using C++:

libcurl:
http://curl.haxx.se/

C++ wrapper:
http://curlpp.org/

php asp doesnt matter

[Galik]

Then CURL is probably a good option for you.

why is it failed. I did directories like this

I only did this are there any necessary things to do

[Bazzy]

You need to linker to the library

[Galik]

Is that eclipse? You need to add the libraries to the build:

Project->Properties->C++ Buils->Settings->Tool Settings->GCC C++ Linker

Then add your library names to the Libraries window. These are probably curl and curlpp

[Morph]

It's visual studio 2008 I did the same thing in the image to linker but it didint work. Are there any documents for visual studio

[Morph]

any answers

[Athar]

The documents are called the help/documentation and Google. Search for "visual studio 2008 link libraries".
