OpenDX 4.3.0 7/7/2003

See http://opendx.org for information and email mailing-list support.

Use the Irix Software Manager or inst to install and remove the OpenDX package.

Compiled on Irix 6.5.15 with MIPSpro Version 7.30 with mips3 extension.

Used HDF 4.1r3, CDF 2.7, and NetCDF 3.5

I have include the CDF shared libraries, which are installed into
/usr/local/lib.

A static version of ImageMagick, the 5.4.5 version I used is available through
opendx.org, http://opendx.npaci.edu/bin/ImageMagick-mips-sgi-5.4.5.tar.gz. I
could not find a current version through imagemagick.org.

Other shared libraries that you should download from SGI
(http://freeware.sgi.com). Some of these may now be included in the latest Irix
Overlays.

libz-1.1.4
jpeg 6b (or 62)
HDF4.1r3
freetype2-2.0.4
bzip2 1.0.1 (may not need?)
tiff 3.4beta (probably already be installed)
netcdf3.5

(There maybe others).

A common problem on the SGI's is a shared memory error.  The following env
variables can be set to eliminate the problem.

setenv DXSHMEM 0
setenv DXMEMORY 128   (or whatever amount of memory you wish to allocate to
OpenDX).

You can also run systune to increase the maximum amount of shared memory (I
increased the shmmax variable).

DOWNLOAD the latest samples (4.3.0) from OpenDX.org or IBM. Unzip and then
untar. Read the instruction on how to install (./configure, make, make install).

Make sure /usr/local/bin is in your path and you can get additional help with:

dx -help
dx -morehelp

Java Explorer works for me on a couple of examples in the dx/java/htmlpages
directory.

Building modules (dx -builder) was working for me in previous versions, but a
couple of changes might be needed if you are using gcc.  You need to edit the
generated makefile and change cc to gcc. You should also add the line DXARCH =
sgi (or setenv DXARCH sgi before running make). You might also have to edit the
dx/lib_sgi/arch.mak since this one was generated for my machine. Loadable,
Outboard and Inboard modules all compiled on a separate computer that lacked
some of the libraries (e.g., CDF and NetCDF) listed in arch.mak.
