Re: Running C++ program from octave ??

[Robert A. Macy]

Henry,  

I have three files named mkoctfile...

mkoctfile.lnk . . . . this is a shortcut on the WinXP
    or, mkoctfile.lin . . on the Win98
mkoctfile.link . . . . text file?
mkoctfile-2.1.50 . . . . this is a text file?
 appears to have all the compile statements in it

Using command line prompt (not octave, but DOS)
mkoctfile generates the standard error message
  Bad command or file name
no matter where typed.  
 GNU octave 2.1.50
   ../bin
   ../octave_files

Can't get passed that point.
