wt

What is Wt ?

Wt is a C++ library for developing web applications. It consists of:

• libwt, a widget/rendering library
• libwthttp, an (async I/O) HTTP/WebSockets server
• libwtfcgi, a FastCGI connector library (Unix)
• libwtisapi, an ISAPI connector library (Windows)
• libwttest, a test connector environment

It also contains a C++ ORM, which can be used in a web application (obviously), but can also be used on its own:

• libwtdbo, a C++ ORM
• libwtdbopostgres, PostgreSQL backend
• libwtdbosqlite3, Sqlite3 backend
• libwtdbomysql, MySQL and MariaDB backend
• libwtdbomssqlserver, Microsoft SQL Server backend
• libwtdbofirebird, Firebird backend

For more information, see the homepage.

Dependencies

To build Wt from source you will need at least CMake, boost, and a C++ compiler like GCC, Clang or MSVC. See the minimum dependency versions for an explanation about which versions Wt supports.

Optionally, you may want to add:

• OpenSSL for SSL and WebSockets support in the built-in httpd, the HTTP(S) client, and additional cryptographic hashes in the authentication module
• Haru PDF library which is used for painting to PDF
• GraphicsMagick which is used for painting to PNG, GIF (on Windows, Direct2D can be used instead)
• PostgreSQL for the PostgreSQL Dbo backend
• MySQL or MariaDB for the MySQL Dbo backend
• An ODBC driver for the Microsoft SQL Server Dbo backend, and unixODBC on Unix-like platforms
• Firebird for the Firebird Dbo backend
• Pango for improved font support in PDF and raster image painting. On Windows, DirectWrite can be used instead.
• ZLib for compression in the built-in httpd.

For the FastCGI connector, you also need:

• FastCGI development kit: you need the C/C++ library (libfcgi++)

Building

Generic instructions for Unix-like platforms or Windows platforms.
