To install the Matlab plugins in directory dir. You can override the default by passing a INSTALL_MEX_DIR to cmake, via (in addition to other cmake arguments): cmake -DINSTALL_MEX_DIR=dir. m files) are installed into INSTALL_MEX_DIR. The Matlab plugins (along with help files and other. Some versions of Matlab also require that you compile NLopt as a shared library in order to produce a Matlab plugin see below. In particular, for Matlab plugins to be installed, you should provide the Matlab installation dir, eg: cmake -DMatlab_ROOT_DIR=/opt/matlab/RYYYYx/.
On most current systems, Matlab and Octave plugins require NLopt to be compiled as a shared library (see above). When you compile NLopt using the above commands, it will automatically compile plugins for both Matlab and GNU Octave (a free Matlab clone) if the latter programs are installed. Then you run make and make install as usual. Just add -DBUILD_SHARED_LIBS=OFF to the cmake flags, as in: cmake -DBUILD_SHARED_LIBS=OFF. The alternative is to compile NLopt as a static library.Ĭompiling NLopt as a static library is easy. Static librariesīy default, NLopt compiles as a shared library (also called a dynamic-link library). For example, if you installed into the /foo/bar directory, so that the library is in /foo/bar/lib, then you would do export LD_LIBRARY_PATH=$:/foo/bar/libĪlternatively, in GNU/Linux systems, you can add the library directory to the system-wide file /etc/ld.so.conf and then (as root) run /sbin/ldconfig. First, you can use the LD_LIBRARY_PATH environment variable. However, at this point you need to tell the operating system where to find the shared library, so that the runtime linker works properly. Note also that the -DCMAKE_INSTALL_PREFIX flag will change the location where the Python plugins are installed, so you may need to change the Python module search path via the PYTHONPATH environment variable.

See also below for how to change the installation directories for Octave, Matlab, and Guile plugins, if you are installing those.

However, now when you compile code using NLopt, you will need to tell the compiler where to find the NLopt header files (using -I) and libraries (using -L) with something like: cc -I$HOME/install/include myprogram.c -L$HOME/install/lib -lnlopt -lm -o myprogram This will create the directories $HOME/install/lib etcetera and install NLopt into them. You would do: cmake -DCMAKE_INSTALL_PREFIX=$HOME/install.
You can do this using the CMAKE_INSTALL_PREFIX variable of the cmake utility.įor example, suppose that you want to install into the install subdirectory of your home directory ( $HOME). You may wish to install NLopt in a directory other than /usr/local, especially if you do not have administrator access to your machine. In the following, we describe a few details of this installation process, including how to change the installation location.

Then install the NLopt libraries and header files via: sudo make installīy default, this installs the NLopt shared library ( libnlopt.so) in /usr/local/lib and the NLopt header file ( nlopt.h) in /usr/local/include, as well manual pages and a few other files. In particular, NLopt uses the standard CMake cmake build system, which means that you compile it via: mkdir build It doesn't require any particular packages to be installed except for a C compiler, although you need to have Octave and/or Matlab installed if you want to install the Octave and/or Matlab plugins, respectively. The installation of NLopt is fairly standard and straightforward, at least on Unix-like systems (GNU/Linux is fine).
