I am attempting to use use the mathlink binaries from Tom Wickham-Jones
book. Although everything seems to compile OK (one warning) it still
does not work. Hopefully someone can recognize what I have overlooked.
Here is what I have done:
I loaded down the newer packages from mathsource and am attempting to
use the Mandelbrot.nb package to test the use of the packages. I am
running V.3.0.2 on a Digital Alpha running DecUnix 4.0D.
Following the instructions, I installed the packages as recommended in
/usr/local/mathematica/AddOns/Applications
# pwd
/usr/local/mathematica/AddOns/Applications/ExtendGraphics
I execute the mcc command link found in the header of mandelbrot.tm
(received a warning that appears insignificant concerning long integers
and the alpha's 64 bit words).
# mcc -o mandelbrot mandelbrot.tm
typedef long double extended_ct;
------------------------^
It produces a file mandelbrot.
However, when inside the Mandelbrot notebook, I exectute the
Needs[ExtendGraphics`Mandelbrot` I get the error message copied below:
In[1]:=
Needs[ "ExtendGraphics`Mandelbrot`"]
LinkConnect::"linkc":
"\!\(LinkObject[\(\"ExtendGraphics`mandelbrot`\", 2, 2\)]\) is dead;
\ attempt to connect failed."
MandelbrotImage::"fail":
"Installation of the MathLink binary mandelbrot failed. The binary
must \ be found for the functions to work."
I noticed that in the xwindow from which mathematica was launched I get
the following messages:
sh: mandelbrot: not found
sh: ExtendGraphics: not found
It appears that there may be a problem with path since both the
directory ExtendGraphics and the file mandelbrot (in ExtendGraphics)
are present. When I load a packgage that does not use mathlink such as
"ExtendGraphics`LabelContour`" it loads fine indicating that there is
not a problem with $Path.
Any suggestions people can give are greatly appreciated? Thanks.
