Hi all,

Have you decided not to run Synchronet on your Rpi because of problems compiling or because you wouldn't be able to run DOS doors? Your problems are over.

Digital Man and Andre put together a great wiki on getting Synchronet to work and I have streamlined the process a little and added instructions to get a Rpi 4 with 64 bit Raspberry Pi OS up and running.

The instructions are here:
http://wiki.synchro.net/howto:raspbian_install

I would like to know if anyone tries it and if they're successful or not and which device they are using. I did try this using Ubuntu and it didn't work out well so I recommend using the latest Raspberry Pi OS. Pick a non-desktop version for best performance so you don't have the graphical interface overhead.

Thanks for writing this up. Not something I'm looking to do right now,
but good to have for possible future reference. Appreciate the effort.

I had a Pine A64+ laying around that I was trying to install Synchronet on. Using DietPi the process could be followed exectly, but I'm getting a segfault when I try to start it up.

GDB backtrace is showing:
(Can't figure out to paste into Putty, dang it...)

Thread 1 (Thread 0x#### (LWP 55229)):
#0 0x#### in js_GetClassPrototype(JSContext*, JSObject*< JSProtoKey, JSObject**, js::Class*) () from /lib/libmozjs185.so.1.0
#1 0x#### in ?? () from /lib/libmozjs185.so.1.0
#2 0x#### in ?? ()

The Pine A64+ is an arm-based processor with this uname -a output:
Linux bbspine 6.1.63-current-sunxi64 #1 SMP Mon Nov 20 10:52:19 UTC 2023 aarch64 GNU/Linux

Not sure what my next step as I'm a little light on debugging crashes with GDB these days.

Does anybody have an idea what I might have missed or is my combination just too unsupported of an OS / Hardware config at the moment?

Thanks,
Ben

The problem is in libmozjs, so I'd suggest trying to build/use the libmozjs that's included in the SBBS repo instead of your system's libmozjs (in /lib).

Well, I didn't use a Pine device and I didn't use DietPi so I don't know. As DM said, could try using the library that comes with synchronet instead.

You'll probably want to build a debug version to get a good backtrace.

I thought that may have been what to try. Glad to have the confirmation. I've been working my way through that included code, although there are some odd type references it doesn't like (doesn't auto-cast FALSE to some pointer types). I think the last place I got stuck on was in the libffi code. I might just give up on DietPI for a little while and try a different distro.

Thanks again!

Just as an update. After trying the internally packaged library on the Pine A64 using Armbian, I ran into a number of issues with compiling libmozjs which I worked through. Then I ran into libffi6 not being compatible with aarch64 and gave up after trying a bunch times. I admit to not knowing a whole lot about programming for different architectures, but porting libffi6 over to aarch64 wasn't going to be something I wanted to do.

In the end I remembered that I had an actual RPi already running another service for me and got Synchronet going on that system on the first try.

Thanks for the suggestions. TL;DR is Pine A64 / Aarch64 doesn't seem like it's quite compatible. RPi sure is, though!
