Instead of using a 'dynamic' version of libpcap, try building the source to libpcap, and then build SIMH, however instead of linking libpcap (-lpcap) have it link the object files from libpcap.... I find building it that way on OSX tended to survive os upgrades.. at least on the PPC versions... I'm x86 less so I can't do much for you... :| On Sun, Aug 30, 2009 at 2:08 AM, Chrissie Caulfield <Christine.Caulfield at googlemail.com> wrote: Gregg Levine wrote: On Sat, Aug 29, 2009 at 1:54 PM, Chrissie Caulfield<christine.caulfield at googlemail.com> wrote: I installed Snow Leopard on my Mac Mini this afternoon (no snide comments please), and it seems to have broken something in libpcap such simh networking no longer works. I've tried a few obvious things to no avail. So my normal emulated router ROOSTA is down at the moment. I've booted up the real VAX called Zarqon to keep the network running and it should be OK for a while, or at least until I need to use that room for recordings. Chrissie Hello! I actually wasn't going to yield to temptation as it happens. However you might want to report the bug to Apple. That cat just came out this week and there are sure as somebody made green apples going to be bugs. I'll need to spend some time diagnosing it properly if I'm to report it to Apple, I suspect just telling them that "simh VAX network emulation isn't working" wouldn't be a very well received bug report ;-) And it's obviously more subtle that just a broken libpcap because my LAT software (which also uses libpcap - though obviously slightly differently) works perfectly, also I copied libpcap from my un-upgraded Mac to test simh, and it's still broken on the new OS, which implies it's something that has changed in the kernel.
