Hi, Thanks for the tip! (I had looked at GRegex but worried about older GLib, but version checking is fine with me) BTW, your answer of "yes" means I cannot safely use plain PCRE, or yes I can safely use it? -hadriel On Sep 18, 2010, at 1:33 PM, Stephen Fisher wrote:

It's in GLib 2.14 and higher: http://library.gnome.org/devel/glib/unstable/glib-Perl-compatible-regular-expressions.html You can block out your wiretap code to only work when compiled with GLib 2.14 (which is most people, including all of the automated builds that people download) by using: #if GLIB_CHECK_VERSION(2,14,0) ... #endif I don't see a problem with blocking out all of the new code, so that file format simply isn't available without GLib > 2.14. That's how we usually handle new features (we don't show it unavailable in the GUI - it just doesn't show up at all). ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
