Type sudo into Terminal, including the whitespace at the end. Open Finder and go to the ‘Install macOS’ app in your Applications folder. Control-click the app and select ‘Show Package Contents.’ Open the ‘Contents’ folder, then open ‘Resources.’. Now, install the Harminv, libctl, MPB, and Meep packages from source. Download Harminv and, in the harminv directory, do./configure && make && make install Use the same commands for libctl, MPB, and Meep. For more detailed information, see Build From Source. You are done, and can now run Meep (Scheme interface) just by typing meep.

Click Download, and it automatically downloads the software package on your system. Find the package and double-click to open the Git installer. Follow the installation wizard and configure Git to suit your development needs.If you are new to version control systems, the best option would be to leave the default settings. Meep runs on any Unix-like operating system, such as Linux, macOS, and FreeBSD, from notebooks to desktops to supercomputers. Conda packages of the latest released version are available for Linux and macOS. There are also Conda packages of nightly development builds which can be used to experiment with new features.

Nowadays, installing FFTW on MacOS X is much like on any othe Unix system. In ancient times, a lot more work was required, and some of those obsolete instructions are preserved below for historical interest.

Installing FFTW on MacOS X

To install FFTW on MacOS X, all you should have the Apple developertools installed, so that you can open up a terminal window and compileFFTW just as you would on any other Unix system:./configure && make to compile, ande.g. sudo make install to switch to root andinstall in /usr/local. (Note that sudo asksfor your password, not root's; alternatively,you can just use su, assuming that your rootaccount is enabled (it isn't by default).)

The multi-threaded version (with POSIX threads) also works fine(./configure --enable-threads).

Precompiled MacOS X libraries via Fink

Instead of the above, the Fink project has puttogether precompiled/prepackaged versions of FFTW 2.x and FFTW 3.x for MacOS X.

Fink provides a collection of free-software Unix tools packaged forMacOS X, based on the excellent package and system-maintainance toolsdeveloped for Debian GNU/Linux

Precompiled packages for CodeWarrior (ancient compiler)

Greg Allen graciously posted a Macpackage of FFTW 2.1.3 and BenchFFT, for CodeWarrior 5 I believe.

In the past, I had created precompiled packages of FFTW for Metrowerks CodeWarrior, includingPPC and 68k libraries. Since my version of CodeWarrior (Pro 2) wasbecoming more and more out of date, I stopped doing this.The last version I packaged in this way was FFTW 2.0.1: fftw-2.0.1.sit.bin.

If you are interested in creating precompiled CodeWarrior packagesof FFTW 3.x (e.g. Selena v1.0.3 – multipurpose wordpress theme free download updates. for MacOS 9), please let us know (and give us a ride on your Tardis).

Compiling FFTW 2.x on MacOS 9

Compiling FFTW yourself on the MacOS is fairly straightforward.For example, this is the outline of the steps to compile thecomplex-transform library using CodeWarrior.

  1. Download and unpack the FFTW archive (.tar.gzformat); StuffitExpander (available gratis) should have no problem with this.(Alternatively, you can download standalone gunzipand untarprograms.)
  2. Create an empty CodeWarrior project for the library, anddrag the fftw subfolder of the FFTW package onto theproject (this will add all the .c and .hfiles).
  3. Go into the project preferences, change the project type to alibrary, and turn all the optimizations on. You will also also needto go to 'Access Paths' and move the fftw folder into the'System Paths' section (since our code includes it as<fftw.h>).
  4. Compile.

To compile the corresponding test program (fftw_test),you'll create a 'console ANSI C' project, adding the library createdabove and the files fftw_test.c andtest_main.c (in the tests subfolder); you'llalso need to modify the access paths as above.

Compiling the rfftw transforms is similar, except that you use therfftw folder, and rfftw_test.c for the testprogram.

CodeWarrior Bugs

CodeWarrior Pro 4 reportedly generates incorrect code whencompiling FFTW 2.x at the highest optimization level (level 4).Supposedly, this problem is fixed in CodeWarrior Pro 5 with all thelatest updates applied. (Thanks to Dan Melomedman for the report, andfor bugging Metrowerks about this.) We haven't heard of problems withother versions of CodeWarrior.

Using FFTW 2.x with the Absoft Compilers

Daniel Barth sent us a couple of notes regarding the compilation ofFFTW 2.x using Absoft's C/C++ and Fortran compilers, version 6.2(circa 2001).

First, the Absoft C compiler seems to have trouble with the Unixline endings (line feeds) in the source files. The source files canbe converted to use Mac line endings (carriage returns) via a programlike NetStripper.

Second, in order to link with Fortran programs using Absoft's ProFortran, add a #define FFTW_FORTRANIZE_UPPERCASE 1 statement to the fftw/config.h file.
