WARNING: I found f2c but not libf2c.a, or libF77.a and libI77.a

| Hi !
|
| I am new to Octave and indeed have been safely cocconed in windows so far so 
I am having a tough time trying to make a binary version of octave.
|
| Based on John Eaton excellent readme.txt I have downloaded cygwin, and octave 
and am trying to now run ./configure in cygwin to create a makefile.
|
| Initially, I had issues since it was unable to find a fortran compiler or f2c 
- however i was able to locate some version of f2c from the web and now 
configure works - but ends with a warning "WARNING: I found f2c but not 
libf2c.a, or libF77.a and libI77.a"
|
| now i do have a directory called libf2c - but it doesnt have anything called 
libf2c.a there are just some "libf2c.sy" and "libf2c.lbc" files. So, I am 
wondering how to compile/build libf2c.a assuming that it is critical to do so. 
also are the other two files libf77.a and libI77.a files that I need to get ?
|
| thanks much

I've used the pm3d mode of gnuplot to plot images like this.  The code
below are my gimage.m and gimagesc.m, which work somewhat like image and
imagesc.  You can, however, put this in a loop like:

   [x,y]=meshgrid(-10:10,-10:10);
   z=sin(x/3).*cos(2*y/5);

   for t=[-5:.1:5 5:-.1:-5]
     gimage(z*t*32+32);
   end


                        hope this helps!

   gset cbrange [0:64];
   gsplot (rot90(im,-1));
