Linking MATLAB to a DLL library

Question

I am trying to execute some example code from a MATLAB toolkit, \'oscmex\'. This toolkit allows for communication using the OSC protocol over MATLAB. I presume this question

Answer 1

Browsing this library's web page it would seems these DLLs are just old form of mex files.
Therefore, they should not be used in the context of shared library (e.g., using loadlibrary and calllib), but rather compiled directly to mex files.

To do so, I would suggest the following steps:

1. Make sure you have a working mex compiler configured for your Matlab.
   In matlab, type:

   >> mex -setup
   

   this will guide you through the configuration process. I understand that you are working on a windows machine, I usually work with visual studio compiler - works best for me.

2. This library's README file suggests that OSC

   requires liblo 0.22 or later. See http://plugin.org.uk/liblo/

   Make sure you have this library and it is located in you LD_LIBRARY_PATH (see e.g., this question for details, or the mex docs).

3. Get the source code for OSC library from their repository.

4. Compile the sources in matlab using

   >> mex -O -largeArrayDims osc_free_address.c
   >> mex -O -largeArrayDims osc_free_server.c
   

   and so on for all 7 c source files. After mex-ing the c files you'll have mex files that you can run from Matlab as if they were regular functions.
   You may find it useful to use the library's make file, as suggested by Andrew Mao.

Good luck,
