Hi Guy,
OK, what do you think about the following workaround:
Index: dumpcap.c
===================================================================
--- dumpcap.c (revision 29584)
+++ dumpcap.c (working copy)
@@ -250,7 +250,11 @@
/*
* Timeout, in milliseconds, for reads from the stream of captured
packets.
*/
+#if defined(__APPLE__) && defined(__LP64__)
+#define CAP_READ_TIMEOUT 1000
+#else
#define CAP_READ_TIMEOUT 250
+#endif
/*
* Timeout, in microseconds, for threaded reads from a pipe.
*/
Best regards
Michael
PS: Wireshark compiles fine on SnowLeopard, only glib-2.20.5
does not compile out of the box...
