Hi

Thank you all for the replies, very appreciated,

yes I did of course include -lm. I use other math functions and it is
alright, only long double functions are missing. So, are they not
included on cygwin entirely, or should I download a newer libc? I just
downloaded and installed from the nearest mirror thinking the latest
will come any way

thank you again,

kind regards,

Manal
