FUDLibrary is available as a Windows binary, but you are welcome to build it from the source code. To build it you need the Borland C++ v5.5 compiler. This compiler is available free from Borland. In addition you need a copy of dmake. dmake is available from www.wticorp.com. A Win32 binary release of dmake was produced by Gurusamy Sarathy and is available from CPAN. Type, for example,
dmake -f makefile.win install
to build.
The import library supplied for ib_util.dll is not compatible with BC55 so the makefile builds its own import library.
