System requirements
For building and installing the latest version of Wt, you need at least the following two packages:- CMake cross-platform make configure
utility.
CMake >= 2.6 is preferred (although by the act of a miracle, 2.4 still works). -
The indispensable
boost C++ library: boost-1.36 or later.
The following boost libraries (which are not headers only) are needed: boost_date_time, boost_regex, boost_program_options, boost_signals, boost_system, and optionally (but highly recommended) boost_thread.
- PostgreSQL: if available, then also a postgres connector will be built for the ORM library (Wt::Dbo)
- libharu: if available, a WPdfImage paint device will be built, allowing to integrate graphics into PDF documents or be served as a PDF document.
- GraphicsMagick: if available, a WRasterImage paint device will be built, allowing to paint graphics on a raster image (like PNG or GIF).
The other requirements depend on the connector support you would like. The connector is what makes your Wt application communicate with the browser:
For FastCGI (Unix only):
- Apache 1 or 2, or another web server which supports the FastCGI protocol.
- FastCGI development kit : fcgi-2.4.0
-
When using apache:
Apache mod_fastcgi:
mod_fastcgi-2.4.x.
Alternatively you may use mod_fcgid: mod_fcgid-2.3.5.
For the built-in http deamon, wthttpd:
- The built-in httpd requires the boost asio C++ library, which is a header-only library included in boost.
- Optionally, libz (for compression-over-HTTP) and openssl (for HTTPS support).
For ISAPI (Win32 only):
- The ISAPI connector only works for deploying Wt applications withing a Microsoft IIS server.
Git repository
