How to install and use Wt (web GUI library) in WSL

Question

I'm using WSL2 (Debian) on Windows 10.

How can I install and use Wt library?

When I try to use the recommended command on the Wt website

$ sudo apt-get install witty witty-dev witty-doc witty-dbg witty-examples

I get this:

Downloads

• Wt from https://www.webtoolkit.eu/wt (e.g. wt-4.5.0.tar.gz)
• Boost from https://www.boost.org/users/download/ (e.g. boost_1_75_0.tar.gz)

Required Packages

$ sudo apt -y install g++ cmake

Install Boost Library

$ tar xvfz boost_1_75_0.tar.gz
$ cd boost_1_75_0
$ ./bootstrap.sh
$ sudo ./b2 install

The header files and the libraries are in /usr/local/include/boost and /usr/local/lib, respectively.

$ sudo ldconfig /usr/local/lib    # Update ldconfig cache

Install Wt Library

$ tar xvfz wt-4.5.0.tar.gz
$ cd wt-4.5.0
$ mkdir build
$ cd build
$ cmake ../
$ make
$ sudo make install
$ make -C examples   # optional

Try It

(examples required)

$ cd examples/hello/
$ ln -s ../../../resources/
$ ./hello.wt --docroot . --http-listen 0.0.0.0:8080
