Hi,
We are using 128 channel Biosemi Active Two device. We are working on a BCI
project, where we want to acquire data in real-time from Biosemi.
We are trying to incorporate fieldtrip real time buffer for our real time
data acquisition. For the implementation we are following the steps
provided on the fieldtrip website. We are getting certain errors during
this implementation for which we request your guidance.
Windows:
We are using Windows 7, 64 bit system.
Installed Softwares:
Microsoft Visual C++ 2005, 2008, 2010, 2012 and 2013
Microsoft Windows SDK 7.1
MinGW compiler and MSYS
Cygwin
1. The matlab inside part of buffer compilation, i.e creation of mex file
on matlab using 'compile' in src/buffer/matlab directory, gave the
following error.
We tried it using Visual Studio and minGW compilers.
*>> mex -setup *
*MEX configured to use 'Microsoft Windows SDK 7.1 (C)' for C language
compilation.*
*Warning: The MATLAB C and Fortran API has changed to support MATLAB*
* variables with more than 2^32-1 elements. In the near future*
* you will be required to update your code to utilize the*
* new API. You can find more information about this at:*

2. The matlab outside part compilation of buffer in src/buffer/src
directory was attempted using make in cygwin terminal. We got the following
error:

Please help us debug the same.
Thank you.
