Installation Requirements for Priism 4 on Mac OS X

Operating system

The software should be compatible with PowerPC systems running Mac OS X 10.2 or later. The software should be compatible with Intel systems running Mac OS X 10.4.4 or later.

Required libraries and additional software

X

It is necessary to have the X libraries installed (libXt.6.dylib (compatibility version 6.0.0), libXp.6.dylib (compatibility version 6.2.0), libXext.6.dylib (compatibility version 6.4.0), libXi.6.dylib (compatibility version 6.0.0), and libX11.6.dylib (compatibility version 6.2.0) are used). Apple's X11 or XDarwin provide them; other X servers will as well. The libraries are expected to be in /usr/X11R6/lib; if they are not there you may need to set the DYLD_FALLBACK_LIBRARY_PATH environment variable so that they can be found (the dyld man page explains DYLD_FALLBACK_LIBRARY_PATH). If you are still using XFree86 4.2, we recommend you update XFree86 to 4.2.0.1 or later. There are some unresolved problems running Priism with newer versions of the X libraries (such as those included with XFree86 4.3 and Apple's X11); search the list of known limitations for "OS X" to know what problems to expect.

OpenGL/Mesa

To use the components with graphical interfaces, it is necessary to have OpenGL libraries (or their Mesa equivalents) installed which can perform the rendering in conjunction with the X server (libGL.1.dylib (compatibility version 1.2.0) is used). Both Apple's X11 and XFree86 provide these libraries. As with the X libraries, the OpenGL libraries are expected to be in /usr/X11R6/lib.

Optional libraries and additional software

Matlab

Priism includes the ImgToMat and MatToImg tools to convert Priism image files to and from Matlab's .mat files. To use those converters, you'll have to have Matlab 6.5 or 7 installed.

Disk space

During installation, you will need space for the downloaded archive and the uncompressed files; the uncompressed files do not need to be on the same disk as the downloaded archive. Once the software is installed, the downloaded archive may be deleted. The space required is 95 megabytes during installation and 70 megabytes afterwards.

While the software is running, it makes extensive use of a shared memory file and related temporary files. The amount of space needed for these files depends on the size of the data sets loaded, but a minimal configuration should have 200 megabytes of space available for these files and having approximately 500 megabytes of space available would be better. Step 4 of the installation procedure describes how the default location for the shared memory and temporary files is set in the sample setup scripts.
