curve

[Adam Majewski]

Hi 

I try to compile curve example

gcc curve.c -lm -ldislin
curve.c: In function ‘main’:

Dear Adam,

there are two versions of dislin.h. One is for float variables in the dislin directory, the other

for double variables in the dislin subdirectory real64. I think that you have included the wrong

dislin.h file in your program.

With best regards,

Helmut
