It is supposed to pass. Can you share more details? It doesn't look
like an endianness issue, at first sight..
Adding '-trace vnc*' and setting _VNC_DEBUG in "vnc.h" I get:
Bail out! FATAL-ERROR: vnc-error: Unsupported auth type 5489072
^^^^ This specific message is comnig from the gtk-vnc client rather
than QEMU
Still doesn't tell us if the flaw is server or client side. The
logs from QEMU are insufficient. In theory it should be reporting
auth type == 0 though, for 'no auth' configs.
Does that help? What else can I do to gather more info?
Modify vnc-display-test.c to call vnc_util_set_debug(TRUE);
before vnc_connection_new(), to get the gtk-vnc debug logs
to stderr too.
