My initial guess would be that the headerfile you have called for is not existent, or is called by another name in Fedora. Try checking man for the function name to see what header is required. Or worst case you may find that this function doesn't exist in the standard development libraries and you have to yum some different library and header to get it. Hope this helps. Regards, Les H
