That is the usual mechanism to detect that the mex file is missing. By
default Matlab will execute the mex file (if available) and will only
fall back to the m-file if the mex file is missing.

Yes. And the source code for the mex file requires an additional
library, which was released as open source software by the
manufacturer. A copy of the open source ANT source code is available
from ftp://ftp.fcdonders.nl/pub/fieldtrip/external

I am planning to move the ANT/EEProbe mex files and associated source
code to a seperate directory under fieldtrip/external/eeprobe to make
more clear that it is not a fully integral part of the regular
fieldtrip release

contrary to the previous mail you are referring to, the ANT source
code is now available. So you might be able to fix it without help
from ANT.

The ANT source code is platform aware and I know that it can be
compiled on a variety of operating systems and hardware (SGI, i386,
dos, windows, linux, irix). However, you probably have to make some
modifications to the Makefile.
