    Hello!!
    While trying to run GSL doc's example (Ch 14, eigen values), we get a problem.

    The program runs, displays the eigen values correctly, but in the last iteration of the loop, throws the following exception

    An exception Breakpoint
    A breakpoing has been reached
    0x80000003 occured in the application at location 0x7801e605

    Any ideas for help?

    Thanks in advance
    O.

      Hi-

      I'm not sure what's causing your difficulty.

      I copied the Ch 14 example code into a source file, compiled it with MinGW linking with either the gsl/gslcblas static or dll libs, and ran it. It ran to completion without any exceptions. I ran it in gdb to be sure, and it ran normally. Here's the output I got:

      c:\dev>gcc -Ic:/tools/gnu/include test-gsl.c c:/tools/gnu/lib/libgsl.a c:/tools/gnu/lib/libgslcblas.a -o test-gsl.exe

      c:\dev>test-gsl
      eigenvalue = 9.67023e-005
      eigenvector =
      -0.0291933
      0.328712
      -0.791411
      0.514553
      eigenvalue = 0.00673827
      eigenvector =
      -0.179186
      0.741918
      -0.100228
      -0.638283
      eigenvalue = 0.169141
      eigenvector =
      0.582076
      -0.370502
      -0.509579
      -0.514048
      eigenvalue = 1.50021
      eigenvector =
      0.792608
      0.451923
      0.322416
      0.252161

      The exception you reported sounds like a debugger breakpoint rather than an exception in the executable. What compiler are you using -
      VC7, MinGW, or something else? Could you be running in debug mode and have a breakpoint set?

      If you're still having problems, feel free to post more details.

      Thanks,

      Jerry
