[Ipopt] Linking problems in MinGW

[Antonello Lobianco]

Thank you, linking the fortran libreries worked.
For those that have troubles in compiling ipopt under windows with g++
actually it is pretty simple. This is how I done it:

*** MinGW ***
Download the MinGW environment installer (
http://sourceforge.net/projects/mingw/files/Installer/mingw-get-inst/mingw-get-inst-201XXXXX.exe
)
Launch the installer
Select "Download latest repository catalogue"
Select C:\MinGW as folder. Do not change this setting !!
Select the following components:
  - C compiler
  - C++ Compiler
  - Fortran Compiler
  - MinGW Developer Toolkit
Open a MinGW shell: START->All programs-> MinGW-> MinGW shell
Type "mingw-get install msys-wget" (you'll need this in order to get ipopt
third party libraries)
Note: From the MinGW shell you'll find the hard disk content under "/c"

*** Ipopt ***
Downolad ipopt Ipopt-3.XX.X.tgz from
http://www.coin-or.org/download/source/Ipopt/ and extract it to somewhere
where there is no spaces in the path (e.g. in Win7 the standard "Download"
folder is fine, in WinXP it isn't.). In the remaining of this tutorial
we'll assume that the ipopt folder is C:\ipopt.
In the ipopt extracted folder create a "build" folder, so that you end up
having C:\ipopt\build.
Open the MinGW shell and type "cd /c/ipopt/ThirdParty".
For each of {Blas|Lapack|Metis|Mumps} go in their subfolder and run from
there "./get.{Blas|Lapack|Metis|Mumps}". This will download and extract
them to a place that the ipopt configure will find them.
Type "cd /c/ipopt/build" and then from there run, in the sequence:
../configure
make
make install

Kind regards to everyone,
  Antonello
