View source for Programming Reference:Building BCI2000 for Win64 (obsolete)

This information applies if you intend to build 64-bit executables. Alternatively, you may build 32-bit executables and run them on 64-bit platforms as well. In oder to build BCI2000 for the Win64 target, you will need to manually perform a number of steps.
==Install Qt for x64==
Rather than building BCI2000 against the Qt distribution coming with its source code, you will need to install a separate version of Qt on your machine.
The following steps have been tested with Qt 4.6.3.

1. Download and install a recent version of Qt.

2. Add your Qt installation's qt/bin directory to the system search path.

3. From the Start menu, open the Visual Studio x64 Command Prompt.

4. <tt>cd</tt> to your Qt installation's qt directory, and execute the following command:
 configure -static
 -no-sql-sqlite
 -no-qt3support
 -fast 
 -qt-zlib
 -qt-gif 
 -qt-libpng 
 -qt-libmng 
 -no-libtiff 
 -no-libjpeg 
 -no-phonon 
 -no-webkit 
 -no-scripttools 
 -no-style-plastique 
 -no-style-motif 
 -no-style-cde 

5. Compile Qt by executing <tt>nmake</tt>.

==Generate the Visual Studio Solution file==
Edit the file <tt>build/cmake/FindQt.cmake</tt> to read SET( USE_STD_QT TRUE ) in line 10.

Then, from your BCI2000 installation's <tt>build</tt> directory, execute the "Make VS2008 Win64 Project Files" batch file.
After successful execution, you will have a Visual Studio solution file ready to compile BCI2000.

==Limitations==
You cannot build BCI2000 modules that depend on 32-bit libraries, as do most source modules.
Consider building 32-bit executables instead--these will run fine on Win64.
