[Ipopt] Ipopt matlab 64 bit interface

[Tony Kelman]

If all you want is the Matlab interface to Ipopt and you're okay with using 
the Mumps linear solver, I recommend you have a look at OPTI Toolbox here: 
http://www.i2c2.aut.ac.nz/Wiki/OPTI/. It comes with precompiled ipopt.mexw32 
and ipopt.mexw64 files.

If you need a different linear solver or would prefer to compile Ipopt 
yourself, there are quite a few extra steps for Windows with 64-bit Matlab. 
Can you answer the following questions?
-Which installation procedure, specifically, are you referring to?
-The error message is occurring in Matlab? Do you have multiple versions of 
Matlab installed on your computer, is it possible you compiled the mex file 
with a different version than you are trying to run it with?
-Are you using MinGW-64? Which distribution?
-Are you using Gnumex? Have you fixed the known issues with Gnumex on 64-bit 
Matlab (replace 'mexw32' with mexext, replace win32\lcc with 
win64\microsoft, and create a shortpath74.m or shortpath74.mexw64 file - see 
Gnumex's Sourceforge bug tracker for more information)?
-Have you made the necessary changes to 
Ipopt/contrib/MatlabInterface/src/Makefile? These include setting 
MATLAB_HOME to the output of the "matlabroot" command in Matlab, setting 
MEXSUFFIX to the output of the "mexext" command in Matlab, setting "MEX = 
$(MATLAB_HOME)/sys/perl/win32/bin/perl $(MATLAB_HOME)/bin/mex.pl", and 
removing -cxx from MEXFLAGS.
-Have you made the necessary changes to mexopts.bat? These include changing 
"COMPILER=gcc" to "COMPILER=g++", changing "GM_MEXLANG=c" to 
"GM_MEXLANG=cxx", and adding 
"-L$PATH_TO_IPOPT_LIBS -lipopt -lcoinmumps -lcoinmetis -lcoinlapack -lcoinblas 
 -lgfortran -lpthread" to GM_ADD_LIBS.

-Tony

Hello,
?
I've tried to install the IPOPT interface on Windows 7 64 bit and 
Matlab2010b 64 bit, but I have some trouble. I followed the installation 
procedure on IPOPT webside, but at the end when I wanted to run an example, 
I have the following error?message:
?
Invalid MEX-file??
ipopt.mexw64 is not a valid Win32 application
?
Invalid MEX-file??
'C:\IPOPT\MinGW\CoinIpopt\build\Ipopt\contrib\MatlabInterface\src\ipopt.mexw64':
?C:\IPOPT\MinGW\CoinIpopt\build\Ipopt\contrib\MatlabInterface\src\ipopt.mexw64 
is not a valid Win32 application
?
?
Do you know something about this problem? Could?anyone help me pls?
?
I guess there is something 32 bit left in project or something else.... Is 
there?any special procedure for 64bit? What should I change?
?
Thank you,
Best regards,
Soma
