For the last few months Skype has been crashing every time I tried to start it on my MacBook Pro. There were error messages in the crash log like this
Thread 0 Crashed: 0 <<00000000>> 0xffff07d7 __memcpy + 55 (cpu_capabilities.h:228) 1 ...ickTimeComponents.component 0x991fa700 _SGVideoGetChannelDeviceList + 2069 2 ...ple.CoreServices.CarbonCore 0x90cd0a53 CallComponentFunctionCommon + 513 3 ...ickTimeComponents.component 0x991edb29 _SGVideoComponentDispatch + 123 4 ...ple.CoreServices.CarbonCore 0x90cd0738 CallComponentDispatch + 34
Which led me to think it was something to do with Quicktime and/or video. So it occurred to me that starting iChat and opening the video preview before starting skype might help. It does!
Earlier I wrote about a problem with libpcap on OS X. This is the call in the code that breaks the wireless connection.
/* ask pcap to find a valid device for use to sniff on */ dev = pcap_lookupdev(errbuf);
but replace it with this (en1 is my wireless interface)
dev="en1";
and then use dev in other libpcap functions and it works fine.
The other day I was playing with libpcap on my MacBook Pro. Every time I tried to run the code my wireless network connection was disconnected.
After a bit of playing around I also found this was happening with tcpdump. It appears that running tcpdump -i en1 where en1 is the wireless network interface works fine. I guess the problem is something to do with the call to scan for interfaces.
