[Ipopt] Ipopt 3.7.1, Matlab interface on Windows

Thu Oct 15 12:08:03 EDT 2009

Dear Ipopt'lers,

with the updated instructions on the Ipopt homepage it is really easy
to successfully compile Ipopt 3.7.1 on Windows (Win32, Cygwin, MSVC
9.0).
However, I have been unsuccessful at compiling the Matlab interface
(R2009b), with "mex -v", obtaining the following error:

  C:\PROGRA~1\MATLAB\R2009B\BIN\MEX.PL: Error: Link of 'ipopt.mexw32' failed.

Did anyone in this group manage to compile and run the Matlab
interface on 32-bit Windows?

Thank you,
Sebastian
