刚开始出现undefined reference to `__chkstk的错误。

然后在vc里面找到chkstk.obj放到相关目录下并在工程文件直接添加：

LIBS += "E:\QTProjects\RTMP\RTMPDelayTest\librtmp\lib\chkstk.obj"

又出现了新的错误

E:\QTProjects\RTMP\RTMPDelayTest\librtmp\lib\librtmp.lib(tmp32\rand_win.obj):-1: error: undefined reference to `@__security_check_cookie@4‘

E:\QTProjects\RTMP\RTMPDelayTest\librtmp\lib\librtmp.lib(tmp32\rand_win.obj):-1: error: undefined reference to `_except_handler4‘
