Qt stream control transmission protocol (sctp)

由 坚强是说给别人听的谎言 提交于 2019-12-11 02:23:48
问题 I am attempting to run the qt examples multistreamserver & multistreamclient, which rely on the QSctpServer & QSctpSocket. I receive errors "QSctpSosket does not name a type" and "invalid use of incomplete type 'class QSctpServer'" What is going on? Running Ubuntu 16.04, Qt 5.10.1 回答1: SCTP functionality does not exist in windows... so by default sctp is disabled. You must configure qt with the -sctp flag and the -static commands, make sure to link any libraries you need as well. 来源： https:/
