Installing Wt on MinGW¶

MinGW requirements¶

This guide used the TDM-gcc (4.5.1-tdm-4).
The shell commands were executed in the 'MinGW Command Propmpt' of the TDM-gcc installation.

Build Boost¶

First, bootstrap boost

cd boost_1_43_0
bootstrap.bat

Before building boost, consider to apply the two patches provided below. These are bugs that may be fixed in future versions of boost and cygwin, but compilation of Wt failed whith boost 1.44 and TDM-gcc 4.5.1-tdm-4.

Build the required libraries

bjam --prefix=i:/mingw-libraries/boost link=static threading=multi --layout=versioned --toolset=gcc --with-date_time --with-filesystem --with-program_options --wit-random --with-regex --with-signals --with-system --with-thread install

This only builds the required libraries. It will take a while before boost is installed. If the boost.random library does not exist for your boost version, then simply omit it from the bjam command line.

Note: If you get link errors with boost.thread, Tomasz Kalicki points out that you may want to fix the boost header files. This is not necessarily required for Wt versions newer than 3.1.5 as those will define BOOST_THREAD_USE_LIB when not linking to a dynamic boost (-DBOOST_DYNAMIC=OFF), but you may want to use it anyway if you use boost.thread in your own application.

Build Wt¶

cmake c:/cygwin/home/Wim/projects/wt-git/wt -DBOOST_DIR=i:/mingw-libraries/boost -DBOOST_COMPILER=mgw45 -DBOOST_VERSION=1_44 -G "MinGW Makefiles"

Then build Wt and the examples

mingw32-make

The Isapi connector is not built under MinGW because the httpext.h file provided with MinGW misses several declarations. I suspect that with a complete httpext.h header, it is possible to build the isapi connector without problems.
