Issues building on Ubuntu 14.04 LTS

[eswenson1]

I tried building base-ks-its on Ubuntu 14.04 LTS and ran into build issues, and after fixing the easy one preventing kn10-ks from building, could not bring up ITS.

The compilation issue is a reference to asm/io.h in dvlites.c. This was easily fixed by changing "asm" to "sys". This fix allows kn10-ks to build. Another issue prevented dpimp from building having to do with "struct ifreq" not having a member named "ifr_space".

But most importantly, ignoring the failed dpimp build, and trying to run ITS with "kn10-its klh10-md.ini", KLH10 makes it through the ".ini" file, but when I try to start (by typing "GO"), I get the following error:

KLH10# go Starting KN10 at loc 0144430...

I'll have to look later at the build things; I normally use NetBSD to build and that probably makes a difference. Regarding the latter, do you have the PI-ITS-RP06.0-dbd9 file? It's the disk that ITS runs on. It was never included in the klh distribution but it can be found here and there. I found it at ftp://ftp.trailing-edge.com/pub/PI-ITS-RP06.0-dbd9.bz2 .

I do. But I've managed to the panda-dist up and running, since trying your source tree. I think the failed builds left one or more of the required binaries not built and therefore missing from the run directory.

I haven't tried ITS much actually. I'm not even sure if I tried it with my changes, I was mostly looking at the Panda TOPS-20.

I pushed some fixes for your compilation issues, and fixed some other errors too that were shown by compiler warnings. For me, ITS now works as well on Linux as it does for me on NetBSD,which is unfortunately not quite :(

It doesn't seem to accept input at this point, where I suppose it should allow logins.

Hm, just after writing that and hitting all keyboard keys, it seems that typing ^N helped. Or ^C. After a while... it seems a bit random. Maybe it's a scheduling thing with a messed up clock (because of the "You're all alone, Fair share = 2%" I saw).

It also helps if your xterm is in vt52 mode.

By the way, I had the same issue with dpimp not working. I did set the suid bit on dpimp, but that didn't work. So I ended up removing the setuid bit and running the simulator as root. That managed to get dpimp to come up without error.

Yes, running as root prevents that message. About the login issue: I vaguely recall reading something about that somewhere. Which is a bit useless. In the mean time I'm closing this issue because your original point, building on Linux, should be fixed now. Thanks for reporting it!
