Programming Reference:Building BCI2000 for Win64 (obsolete): Difference between revisions

Latest revision as of 16:34, 8 June 2022

NOTE: This page is outdated, and only retained as a reference. Building BCI2000 for 64-bit target does no longer require the manual steps described here.

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, and should generally work with Qt 4.7.x as well.

1. Download and install a recent SDK version of Qt.

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

3. In the file qt/mkspecs/win32-msvc2008/qmake.conf, or the corresponding file for MSVC2010, apply these changes: In QMAKE_CFLAGS_RELEASE and QMAKE_CFLAGS_DEBUG, replace the -MD and -MDd switches with -MT and -MTd, respectively.

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

5. cd to your Qt installation's qt directory, and execute the following command:

configure -static
-no-sql-sqlite
-no-qt3support
-fast 
-qt-zlib
-qt-libpng 
-qt-libmng 
-no-libtiff 
-no-libjpeg 
-no-phonon 
-no-webkit 
-no-scripttools 
-no-style-plastique 
-no-style-motif 
-no-style-cde

6. Compile the required parts of Qt by executing nmake in these directories:

qt/src/corelib,
qt/src/gui,
qt/src/winmain,
qt/src/opengl.

Generate the Visual Studio Solution file

Edit the file build/cmake/FindQt.cmake to read SET( USE_STD_QT TRUE ) in line 10.

Then, from your BCI2000 installation's build 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.

Notes

You cannot build x64 targets using Visual C++ 2008 Express Edition except after considerable unsupported modifications.
