However, I have not been able to use the include file . A simple program, such as: #include #include main() { printf("%d\n",sin(3.0)); } produces an error: "ex2-2.c (.text + 0x24): undefined reference sin" during compilation. If I use another math function in place of sin, I get the same error ( except with "sin" in the error statement replaced by the appropriate function). I have searched through the file math.h and have found that it has a statement: #include in it. However, upon looking through all of my files associated with djgpp, I am unable to find math-68881.h. Could there be a *.zip file that I may need to install? Any suggestions would be helpful. Thanks. Todd Hutchinson
