Hi Brendan,

Thanks for the report, the answer to your original question is that it 
*should* work, but that it is untested and I don't think anyone working 
on gnumex at the moment has experience with fortran. Could you send the 
output of the 'ver' command in Matlab please. I also assume you got no 
errors from gnumex when you ran it about .def files or similar?

My first guess is that the linking issue will be due to the fortran 
libraries lflibmx, lflibmex and lflibmat not being created correctly 
(gnumex must convert these from the libraries supplied by Matlab). This 
is done using the program nm.exe which is supplied as part of the 
MinGW-w64 toolchain. The process is to use nm.exe to first create .def 
files which are text files containing symbols from the library files, 
these are then used to convert the libraries. If you are interested 
these libraries are created around lines

In the meantime, if you find the cause, and/or a workaround please let 
us know.

Richard
