Installing Wt on MinGW

MinGW requirements

This guide used the TDM-gcc (4.5.1-tdm-4). Verified with TDM-gcc 4.7.1.

The procedure also works for mingwbuild for a 64bit target, after working around some compilation/linking issues.

Build Boost

Instructions to build boost may vary slightly from release to release.

You can choose between the 'MinGW Command prompt' and the 'MSYS shell' (msys.bat) to build boost.

From MSYS shell of the TDM-gcc installation:

cd boost_1_52_0
./ --with-toolset=mingw

This builds boost. Then edit project-config.jam and do a search and replace, to replace all mingw in gcc.

Build boost (the context library does not compile on boost 1.52, may be fixed in newer versions):

./bjam.exe toolset=gcc link=static threading=multi --layout=versioned --prefix=c:/Boost --without-context install

From the 'MinGW Command Prompt' of the TDM-gcc installation

Since bootstrap.bat will always use msvs to compile bjam, you need an installed MS Visual Studio compiler to use this method.

First, bootstrap boost

cd boost_1_43_0

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.exe toolset=gcc link=static threading=multi --layout=versioned --prefix=c:/Boost --without-context install

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.

General remarks on boost

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.

When setting up your own makefiles for use with mingw, think about setting BOOST_THREAD_USE_LIB properly on your project if you do not apply this patch.

Build Wt

From MinGW Command Prompt:

cmake c:/path/to/source/of/wt -G "MinGW Makefiles"

From MSYS unix-alike shell:

cmake c:/path/to/source/of/wt -G "MSYS Makefiles"

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.

When setting up your own makefiles for use with mingw, think about setting BOOST_THREAD_USE_LIB properly on your project (see notes on boost above).
