We are working on a BCI project, where we want to acquire data in real-time
from Biosemi. We are using 128 channel Biosemi Active Two device.

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.

We are using Ubuntu 14.04 64 bit. The gcc compiler version used is 4.8.5.
We are using Matlab 2015

1. The matlab outside part of buffer is compiled successfully using 'make'
on command prompt in the directory src/buffer/src/.

2. The matlab inside part of buffer compilation, i.e creation of mex file
was successful on matlab using 'compile' in src/buffer/matlab directory.

These warning was displayed, but the mex completed successfully.

*Warning: You are using gcc version '4.8.5-2ubuntu1~14.04.1)'. The version
of gcc is not supported. Theversion currently supported with MEX is
'4.7.x'. For a list of currently supported compilers

3. For compiling the biosemi2ft tool, this is the error which we get

Please help us debug the same.

Thank you.
