Re: [Simh] THE SOULTION - Segmentation fault when running the MIcrovax emulator
Thanks to those others who tried to help, but Mark Pizzolato managed to get to the bottom of it all. It seems that most of the problem was outdated documentation. I was still trying to use the libpcap from tcpdump, as recommended by Phil Wherry's writeup. At Mark's suggestion, and with the latest version of his code, I downloaded the libpcap from the repositories, removed the USE_NETWORK switch when building SIMH, switched to using the inbuilt TUN/TAP business, and everything now builds correctly and gets past the point at which SIMH was crashing. There should maybe be a note placed prominently on the front page of the SIMH website warning that Phil Wherry's writeup is now incorrect in some respects? Brian.

Re: [Simh] THE SOULTION - Segmentation fault when running the MIcrovax emulator
Hello, I am glad that this issue is solved as well. I wonder, is there any reason why Mark's code is not officially released? Thank you.

Re: [Simh] SimH: Bugfix in VAX/PDP11 TK50 driver: pinging Bob!
Hello Jörg, My name is Geoff Shearer. I found your email address on the Simh mailing list. I hope you do not mind that I contact you directly. In 2010 you mentioned in a post that you had a working Solaris V3 install under Simh. I wonder if you would mind sharing that with me. Ideally, I'd like to install V3 myself. However, the tape at bitsavers does not boot for me. I am not a programmer, just an old software enthusiast, so I am unable to make changes to the Simh binary files. If you are able and willing to provide any wisdom, I would be grateful. Thank you. Geoff Shearer___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
