Under Windows 7

Impossible to make Visual C++ Express work properly: apparently there is something wrong with the compiler:

So I dropped Visual C++, downloaded QT SDK, and went for the MinGW option, building against the standard QT, not the one shipped with BCI2000.

I had the following problems.



First: SpikeLFPGenerator (during cmake)

/////////////////////////////////////////////////////////////////////////////////////

CMake Error at C:/Users/Moe/Desktop/BCI2000/src/contrib/SignalSource/CMakeLists.
txt:16 (ADD_SUBDIRECTORY):
add_subdirectory given source "SpikeLFPGenerator" which is not an existing
directory.

Fix: comment line 16 in src/contrib/SignalSource/CMakeLists.txt


Second: FilePlayback (compilation stage)

Again I commented the FilePlayback line in CMakeLists.txt, because I don't need it (for now).

After that the whole compilation went fine, including the BCPy2000 stuffs.

Brice,

did you try with Visual C++ Express 2008 or 2010? 2010 is not supported currently.

The compilation errors with MinGW will be fixed soon.

Best regards,
Juergen

I tried with visual c++ 2008

Maybe this is a Windows 7 issue -- it works fine under XP.

If you can get access to Visual Studio Professional 2008, then it will work. Check with your school to see if you already have access through MSDNAA or Dreamspark. Also alternatively, join IEEE to gain access to MSDNAA for free. That is an alternative while you wait.
