@eswenson1, are you running KLH10 on a Mac? If so, anything to add here with regards to your success or lack thereof?
I'm not currently. Let me try to build and run.
Update: I did just try to do a make clean EMULATOR=klh10 && make EMULATOR=klh10 download and while KLH10 built, the download target resulted in this:

I tried repeatedly downloading klh10.tgz from hactrn.kostersitz.com, and each time, while the download appears to work perfectly fine, the .tgz has errors extracting. Perhaps it was not properly uploaded the last time?
I'll try a full build, which, of course, is needed to test out this ticket. I was just curious to try the download thing since I haven't ever before.
I'm failing in the same way as previously described:

It hung at this point. So either there is something wrong with the files loaded into KLH10 (e.g. dskdmp.216bin or @.ddt-u), which I doubt, or the built KLH10 doesn't work any more when built on mac. I'll see if I can find an old klh10 I've built and run to see if it does better.
When I start my full build manually with this ./kn10-ks-its ../mchn/DB/nsalv.ini it starts up fine but then crashes when I type the 0 at the format pack # prompt. It looks like yours started at loc 04000 whereas mine starts at 0774000
Is it normal to get this error on startup of kn10-ks-its? I don't recall seeing it before.

➜ klh10 git:(master) ✗
I suspect the inability to allocate memory (first error message on kn10-ks-its startup) is the cause.
I am wondering if this has to do with the new memory protection features in MacOS. For example I had to codesign gdb to actually use it to get it to run and start debugging
I dunno. I had to codesign gdb way before this problem started happening.
Found this in the klh10 install.txt
KERNEL CONFIGURATION
====================
Installation on most UNIX platforms is straightforward except
for two special requirements of the KLH10 emulator, which sometimes
require kernel reconfiguration.
[A] Shared memory; MANDATORY if running any device sub-processes.
The so-called SYSV "shm" system calls must be available, and
ideally should allow shared segments of up to 32MB for a KL10,
4MB for a KS10. The configuration examples below assume a KL10
since it doesn't hurt even if a KS10 is all you will ever run.
If this support is lacking, you will get a warning similar to
the following:
[os_mmcreate: shmget failed for 33554432 bytes - Invalid argument]
which is not necessarily fatal, but less efficient.
maybe this is a red herring?
The code for this lives in ./tools/klh10/src/osdsup.c line 1633 in mine.
From where it calls it in '/Users/mikek/its-klh/tools/klh10/src/klh10.c'
the process tries shared memory first and then moves on the private memory if that fails.
the message seems like a red herring as it is deemed a warning that no shared memory is available.
Maybe I'll update the message text to say WARNING :)
For some reason, I cannot run my old version of kn10-ks-its under gdb. So I'm unable to debug. I get this:
gdb ./kn10-ks-its

mark^[g
I'm hung after the [New Thread...] message from gdb. I never see any messages from kn10-ks-its. The "mark^[g" was a silly/vain attempt to see if it had started without messages and NSALV was waiting for input (it wasn't).
I wonder if shared memory settings need to get updated. This is what I have:
sysctl -a | grep sysv.shm
kern.sysv.shmmax: 4194304
kern.sysv.shmmin: 1
kern.sysv.shmmni: 32
kern.sysv.shmseg: 8
kern.sysv.shmall: 1024
I increased kern.sysv.shmmax to double that amount and I still get a failure. But the value emitted in the error message is still 4194304. I wonder if I have to reboot the system after changing the value? I thought you could simply do sudo sysctl -w kern.sysv.shmmax=xxxxx to change the value until the next reboot? When I run sysctl kern.sysv.shmmax to confirm my setting, I get back:
kern.sysv.shmmax: 8388608
So my change appears to take effect. Not sure why kn10-ks-is asking for 4194304. Can you tell from the code what it wants?
It does look like kn10-ks-its is only wanting 4M, so the 4194304 value is what it is asking for. My "shmmax" value is double that, so the shmget call should succeed. Not sure why it isn't. Googling.....
I found that once it crashes in the terminal window I have to start a new terminal session for the emulator to get to the prompt again. Something in that terminal session gets borked after the crash
Can you use gdb to determine what the error code from the shmget failure is? That might provide a clue.
For me, creating a new shell doesn't fix my inability to run kn10-ks-its under gdb. I never get to see any output from kn10-ks-its after gdb reports that a new thread is created.
I may have to rebuild my kn10-ks-its (good idea anyway). I was able to attach to my kn10-ks-its process from gdb after it was started and see this:

I'll rebuild and retry.
the memsiz is calculated in klh10.c memsiz = (size_t)PAG_SIZE * PAG_MAXPHYSPGS * sizeof(w10_t);
this is what I get in gdb

Need to do a CONTINUE in GDB after attaching so it takes the input on the emulator side.
Yeah, I did. I got:
(gdb) cont
Continuing.
[Inferior 1 (process 7648) exited normally]
(gdb)
and in the gdb session:
MARK$G'
Format pack on unit #0[1] 7648 segmentation fault ./kn10-ks-its ../mchn/DB/nsalv.ini
So no help.
I do not think it has to do with the amount of memory the emulator tries to allocate I changed it to just try 50% of the allocation. No change in behavior.
