Problems with mathlink (and TWJ_ExtendGraphics)

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. ------------------------------------------------------------------------------ Joel W.
