Re: link err with #include<math.h>
Yup, that did it. I'm used to borland and ms c on dos and windows
that seem to pull in these lib's automagicly. I KNEW there was a
linker command to do this but couldn't find it. Where is this
documented, and what other lib's do I need to look out for?
Thanks for the help.
