[Ipopt] interfacing Ipopt with matlab

Fri Jun 4 05:41:45 EDT 2010

Hello Ipopt-experts  and Rodrigo,

I tried to install the Ipopt on my Laptop with windows XP system, and
use the Matlab interface for IPOPt.

According to the suggestions from Rodrigo, I did the following:

- windows XP
- VC 6.0
- matlab R2008b student
- MinGW version 5.1.6
- Msys 1.0.11
- Ipopt version 3.8.0

Details:

   - Download  MinGW/TDM <http://www.tdragon.net/recentgcc/> compilers,
   version 4.3.2-tdm-2 (I've tried other versions, and they don't work)
      1. gcc-4.3.2-tdm-2-core.tar.gz
      2. gcc-4.3.2-tdm-2-g++.tar.gz
      3. gcc-4.3.2-tdm-2-fortran.tar.gz
   - Extract the compiler files with
      1. $ tar xzf gcc-4.3.2-tdm-2-core.tar.gz -C /mingw
      2. $ tar xzf gcc-4.3.2-tdm-2-g++.tar.gz -C /mingw
      3. $ tar xzf gcc-4.3.2-tdm-2-fortran.tar.gz -C /mingw
   - Backup libstdc++* just in case
      1. $ cp /mingw/lib/libstdc++.a /mingw/lib/libstdc++.a.orig
      2. $ cp /mingw/lib/libstdc++.la /mingw/lib/libstdc++.la.orig
   - Copy libstdc++.* to /mingw/lib
      1. $ cp /mingw/lib/gcc/mingw/4.3.2/libstdc++* /mingw/lib/

 1.) get the ipopt code
 2.) get the required ThirdParty code (ASL, Lapack, and BLAS) via the
get comands
 3.) get the HSL as described (ma27ad.f and mc19ad.f)
 4.) mkdir   $MyIpoptDir/build
     cd   $MyIpoptDir/build
 5.)$MyIpoptDir/configure   --enable-doscompile --disable-shared
–-enable-static
                             ADD_CXXFLAGS="-fexceptions"
ADD_CFLAGS="-fexceptions"
                             ADD_FFLAGS="-fexceptions"  CC=gcc CXX=g++
 6.) make
 7.) make test
 8.) make install

===> Up to this point everything seems to work fine. The problem
appears in the next step to generate the matlab interface.

9.) copy the mexopts.bat file generated by gnumex in
$MyIpoptDir/build/Ipopt/contrib/Matlabinterface/src
10.) edit the makefile:

   1.     MATLAB_HOME = /c/PROGRA~2/MATLAB/R2008B~1/
   2.     MEXSUFFIX = mexw32
   3.     MEX =$(MATLAB_HOME)/bin/mex.pl

11.) edit the mexopt.bat

   1. set GM_MEXLANG=cxx
   2. set GM_ADD_LIBS=-llibmx -llibmex -llibmat
   -Ld:\msys\uno\home\Administrator\CoinOR\Ipopt_matlab\build\lib -lipopt
   -lpthread -lm -Ld:/mingw/bin/../lib/gcc/mingw32/4.3.2
   -Ld:/mingw/bin/../lib/gcc
   -Ld:/mingw/bin/../lib/gcc/mingw32/4.3.2/../../../../mingw32/lib
   -Ld:/mingw/bin/../lib/gcc/mingw32/4.3.2/../../.. -L/mingw/lib
   -lgfortranbegin -lgfortran -lmingw32 -lmoldname -lmingwex -lmsvcrt -luser32
   -lkernel32 -ladvapi32 -lshell32 -llibmx -llibmex -llibmat
   3.  set COMPILER=g++

12. ) Then I type make to generate the interface, some errors appear:

        /c/progra~2/matlab/r2008b~1//bin/mex.pl:  line 95: require: command
not found
        /c/progra~2/matlab/r2008b~1//bin/mex.pl:  line 97: sub: command not
found
       /c/progra~2/matlab/r2008b~1//bin/mex.pl:  line107: syntax error near
unexpected token 'else'
       /c/progra~2/matlab/r2008b~1//bin/mex.pl:  line107: ' else'
       make: *** [ipopt.mexw32] error 2

  I read the mex.pl file, the commands" require, sub" are in it, but I
don't know what to do.

   I also tried to edit the MEX in the makefile as:
            MEX =$(MATLAB_HOME)/sys/perl/win32/bin/perl.exe
$(MATLAB_HOME)/bin/mex.pl
    then the errors are:
            /c/progra~2/matlab/r2008b~1//bin/mex.pl: error:
unrecognized switch: -CXX.
            make: *** [ipopt.mexw32] error 2

What should I do, then I can generate the matlab interface successfully.
I am looking forward your help.

Thanks!
