Open Motif for Mac OS X

This page provides downloadable Open Motif (32-bit and 64-bit) packages, suitable for use on OS X on Intel-based processors. Two types of package are provided. The first just contain the static Motif library, libXm.a. This is the only Motif component required by X/Winteracter for development on OS X.

These are the versions of Open Motif which we recommend for use with the current OS X versions of X/Winteracter. They were built from the standard 2.3.6 Open Motif source distribution, but patched to overcome Motif incompatibilities introduced in the XQuartz X server at both of its 2.7.9 and 2.7.10 releases.

I.S.S. has successfully tested applications built with the 64-bit library on OS X 10.9 (Mavericks) and 10.11 (El Capitan). Applications built with the 32-bit library have been successfully tested on OS X 10.5 (Leopard) and 10.9 (Mavericks).

Wherever you extract the Open Motif files, we recommend creating a symbolic link called /usr/local/OpenMotif (32-bit) or /usr/local/OpenMotif64 (64-bit), e.g.

  sudo ln -s $HOME/motif-2.3.6 /usr/local/OpenMotif
or:
  sudo ln -s $HOME/motif-2.3.6 /usr/local/OpenMotif64

Note: In versions prior to 10.10d, we recommended creating the OpenMotif or OpenMotif64 symbolic link in /usr, rather than /usr/local, but that recommendation was not compatible with System Integrity Protection, as introduced in OS X El Capitan. As of 10.10d, the supplied documentation and tools therefore now assume that Open Motif is located in /usr/local rather than /usr.

For completeness, the packages from which the above static libraries originate are also provided below. These packages were built by Interactive Software Services Ltd. We made minor modifications to the standard 2.3.6 sources to allow it to build on OS X and to overcome XQuartz issues noted above (see CHANGES in the full 2.3.6 archive).

As noted above, X/Winteracter users only need to download the static library package. They do not need to download either of the above full packages, which are provided here to fulfil the terms of the Open Group Public License. All of the above packages are made available here according to the terms of that licence.
