NLopt on Windows
NLopt works fine on Microsoft Windows computers. To simplify installation, we provide a precompiled 32-bit Windows DLL, built with MinGW (using this script):
Be sure to read the README-WINDOWS
file included in this zip archive for how to build an import library for the DLL before using, by running the lib /def:libnlopt-0.def
command (which comes with Microsoft compilers). If you are using GNU compilers (MinGW), run dlltool --def-input libnlopt-0.def --dllname libnlopt-0.dll --output-lib libnlopt-0.lib
(dlltool comes with MinGW).
(For source code, download the main .tar.gz
package.)
Alternatively, you can use the following files, provided by Benoit Scherrer (benoitscherrer

), to compile NLopt from source on Windows (with the Microsoft compiler) using CMake:
Octave plugin
To build the NLopt plugin for GNU Octave (a free Matlab clone, which uses the same NLopt interface as in Matlab), you will need the following additional steps. (See Octave for Windows on the Octave web page to download Octave.)
- First, download both the
.zip
file above and the main.tar.gz
package of NLopt. Usedlltool
(which comes with Octave in the octave\mingw23\bin
directory) to create the.lib
import library as explained above. - Unpack the NLopt .tar.gz file, and copy the
nlopt_optimize-oct.cc
from the nlopt\octave
directory, along with downloading nlopt_optimize_usage.h, and put them together with your.lib
and.dll
files (from the.zip
). - Compile the Octave plugin (
.oct
file) withmkoctfile -lnlopt-0 --output nlopt_optimize.oct nlopt_optimize-oct.cc
(mkoctfile
is a program included with Octave). - Finally, move
libnlopt-0.dll
to the octave\bin
directory so that Octave can find it.
