I am trying to build a program for 2D and 3D visualization
of functions with the use of .dxe libraries in the style of:
"Type in a function"
> x*x+y*y
Program plots using a .dxe library made of

#include <math.h>
float function fct(float x, float y)
{
  return <the string typed in>
}

and compiled by a spawned gcc and dxemake.

The problem is that while the expressions containing arithmetic, 
sin and cos work fine, the expressions containing functions like  sqrt or log
give rise to a bunch of linking errors concerning (as I suspect)
arg error handling. In particular, ld complains
about missing _main.

Any ideas?

(I am using djgpp v.2)
Best regards
