[Simh] Problems running simH in Android

Thu May 10 12:37:38 EDT 2018

First, please follow the exact same steps (grabbing the same disk image), using the same configuration file on any of your other favorite simh hosts.  If this produces the same result, then it's not a platform problem.

In any case, precisely describe the steps, configuration file and source of the disk image.

Let me know what you find.

Ok. So I switched to my tablet  (Samsung tab a) running 7.1.1 and things built fine.  I pulled the software kit for rsts and when I tried to mount the prebuilt rl0 the simulator errored.

RL0: non expandable disk rsts_full_r.dsk is smaller than simulated device (2617KW < 2621KW)

File size according to ls -l is 5235200

Any ideas?

Skip the AltairZ80 for now.  The change that caused the redefinition was done to potentially help the AltairZ80 author to fix the glob.h missing issue.

Pull the latest and you should hopefully be able to build all but the AltairZ80 simulator.

I just got that error too and now after doing a make clean, I cannot build anything.

I'm having issues compiling on the note 8 with android 8.

Getting glob.h not found on the altairz80 and most give a warning about redefinition of *DIR_ENTRY_CALLBACK

The github master branch code should now work under termux on Android for at least Marshmallow on up.  I have tested Marshmallow and Oreo.  I would appreciate confirmation on other Android versions:

1)      Install termux from the Google Play Store

2)      Under termux, Install the tool chain:

    $ pkg install clang make git

3)      Testing with:

    $ git clone https://github.com/simh/simh

    $ cd simh

    $ make vax

    $ BIN/vax

    sim> B

If you end up at the >>> prompt everything looks good.  If you did this without a physical keyboard connected, you won’t be able to type Control-E to get back to the sim> prompt.  Just enter B ZZZ which is an unknown device and the boot ROM will halt returning you to the sim> prompt.

Once you get that far, all the other simulators should build fine and be usable pretty much like on most other Linux environments.  Things which require root access won’t work since termux doesn’t give you that.  It would be interesting to know if NAT mode networking works for the VAX simulators…

Hi Ray,

Give the latest github code a try.

BTW, what Android version is running on your phone/tablet?

What is the output of ‘uname –a’ in your termux session?

To follow up a little more on this.

The call to tcsetattr() is failing with errno: 13 – Permission denied

I did a little digging and struggled with typing a whole bunch on my

phone.

The problem you’re seeing is due to the Linux OS environment you’re

running under doesn’t support ‘raw’ mode for terminal I/O.  When you

start a simulator the traffic to/from the simulated console device is

expected to be exactly the characters that the user types on the console

keyboard.  To achieve this, the current tt mode is gathered with tcgetattr()

then those attributes are adjusted so that every character typed is received

without any interpretation by the OS and output is also not translated (i.e.

\n only sends a LF character instead of CRLF characters).  The error message,

you seeing is due to the call a tcsetattr() failing.

If you’re not comfortable digging into this yourself, then please create an

Issue at https://github.com/simh/simh/issues and spell out exactly how to

recreate your setup and reproduce the problem.

Greetings

I have been trying forever to get simh to run under the Termux Android shell app and got very close but no cigar. It builds okay but then when I try running it, it starts fine but when I go to run an OS,  I get this:

PDP-11 simulator V4.0-0 Current        git commit id: f2f4bfa8

sim> do rt1154f.ini

Disabling XQ

rt1154f.ini-3> b rk0

sim_ttrun() returned: Console input I/O error

sim>

Any ideas?

Thanks

Ray
