Try running the external MathLink program directly from the shell's command line. If everything is ok, you should see a prompt that looks like this: Create link: If you are running into the problem that I am expecting, you will see an error indicating a crash instead: segmentation fault This happens when a program is linked against an older MathLink library (libML.a) that was created under either libc 5 or glibc 2.0 and then executed in an environment that runs glibc 2.1 or later. The fix is to get a newer release of the MathLink Developer's Kit for Linux, which is a free download from the WRI Technical Support website. A more detailed description of the problem may be found at this FAQ URL: http://support.wolfram.com/MathLink/Linux/glibc21.html If you have updated your MathLink Developer's Kit already and are still running into troubles, please contact Technical Support directly at <support at wolfram.com> -- P.J.
