I have a problem locating the NET package. Have looked in many ftp sites and can't find any NET package in either Latest or Contrib. Can you help?

What do I miss? Cygwin itself contains a very old implementation of regex which isn't compatible with any standard I'm aware of. But the Cygwin net distro contains two packages regex-4.4 and pcre-3.4 which provide libraries which contain POSIX regex APIs. If you have installed them (recommended), just include the correct headers regex-4.4: regex.h pcre-3.4: pcreposix.h and link with regex-4.4: -lregex pcre-3.4: -lpcre -lpcreposix Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Developer mailto:cygwin AT cygwin DOT com Red Hat, Inc. -- Want to unsubscribe from this list?
