Not that I know of. Note that $(PIE_CFLAGS) is already included in AM_CPPFLAGS in ui/qt/Makefile.am because that's what fixed the problem for me the first time a few months ago. It may have been an unnecessary and/or incorrect way of fixing the issue though. ___________________________________________________________________________ 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-requ...@wireshark.org?subject=unsubscribe
