Hello,

I need to use the ExtendGraphics'TriangularInterpolate package to 
interpolate between irregularly spaced data points.  I need help getting 
the installation correct.

I'm using Mathematica 4.0.1.0 under RedHat Linux v7.2

I've downloaded TWJ's shell install script and installed the files into 
/usr/local/TWJ_Packages.  Using mcc I've built the binaries

mcc -o delaunay delaunay.tm
mcc -o contour contour.tm
mcc -o mandelbrot mandelbrot.tm

Per the README file I've tried testing the installation.

When I try to the commands:

AppendTo[$Path, "/usr/local/TWJ_Packages"]

Needs["ExtendGraphics`Mandelbrot`"]  

I'm given the errors:

LinkConnect::linkc: (LinkObject['./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.?

(http://library.wolfram.com/mathgroup/archive/1999/Apr/msg00346.html)
I've tried recompiling the binaries with .exe extensions

mcc -o delaunay.exe delaunay.tm ...

I've tried moving the binaries to a directory directly in the path
(/usr/local/mathematica/AddOns/Applications) but I still receive the same 
error.

Also from the April 1999 discussion, it appeared that this problem could 
be circumvented by using the Install command.  This also fails for me.

link = Install["/usr/local/TWJ_Packages/ExtendGraphics/mandelbrot.exe"]

LinkConnect::linkc: 
LinkObject['/usr/local/TWJ_Packages/ExtendGraphics/mandelbrot.exe', 7, 2] 
is dead; attempt to connect failed.

I really don't know what to try next, and I don't have any good (simple)
alternatives to using the TriangularInterpolate function included in this 
package.  

Thank you for looking at this for me,
Scott
