Wt

Try a C++ based Wt library for developing web applications.

On Ubuntu, use apt-get

> sudo apt-get install witty witty-dbg witty-dev witty-doc

(ref.http://www.webtoolkit.eu/wt/wiki/index.php/Installing_Wt_on_Ubuntu)

Try examples.

> mkdir ~/wt
> cd wt
> cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples

Oops, need to install cmake.

> sudo apt-get install cmake

Running cmake again created a directory ~/wt/wt-homepage and ~/wt/wtwithqt.

Oops, again. need to install libboost

> apt-get install libboost1.35-dev libboost1.35-dbg

Gee, a lot of files are dependant... 60.7MB download and 358MB disk space consumed

Well, done. Running cmake

> cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples

terminal output

> ~/wt$ cmake -DWT_SOURCE_DIR=/usr/share/doc/witty-doc/ -DEXAMPLES_CONNECTOR="wt;wthttp" /usr/share/doc/witty-doc/examples

Hmmm, some examples are skipped... i found on the mailing list for Wt, it's a bug. will need to build Wt from the current souce to run these skipped examples. Anyhow, see what's created
