Thread Subject: mex linux source for windows

Dear all,

We have a some Linux C-library code that has been
successfully mexed for Linux. Now we would like to
transport this this to the Windows environment.

I have very little experience in this area so all
suggestions would be welcome. I have been searching the
web and found some web pages on mingw, cygwin, and
gnumex. While these seems to be pointing in the right
direction, more direct/specific/hands-on suggestions and
experience would be most welcome.


Many thanks,
Lars

Hi Lars,

if you want to create Windows MEX files using a Unix style build
environment, you have to setup a cross-compiler (either Linux:MinGW
or Cygwin:MinGW). Then compilation is as easy as

# Directory containing a copy of $MATLAB/bin, $MATLAB/extern, and
# $MATLAB/simulink/include from a Matlab Windows installation.
export MATLAB=/opt/w32/matlab-6.1
export MATLAB_ARCH=win32
export MEXEXT=dll
/configure --build=i686-pc-linux-gnu --host=i686-pc-mingw32

Ralph,
Do you know if it is possible to use a Linux compiled mex
function as a s-function in Simulink (DOS). Or is there
another cross compiler required to do this?
