Segment fault error occurs when deploy node-red-node-serial in openWRT

[vincentlin_artt]

Hi, experts:
First, I'm new for this forum but loved node-RED very much and used it for education years.
Here is my environment:

1. raspberry pi cm4(8G/8G) with a motherboard.
2. opwnWRT kernel version:5.10.113
3. version of node.js:16.15.1, npm: 8.11.0
4. install node-RED and node-red-node-serial via:
   4.1 opkg update
   4.2 opkg install node && node-npm
   4.3 npm i -g node-red
   4.4 manage palette > install > node-red-node-serial

Everything runs well except I define a serial-port node then deploy it, then segment fault occurs,
I tried everything as far as I know, still unable to solve it, hope anyone of you can help me.

ps. character device /dev/ttyAMA1 is working fine with minicom connection test, so I thing H/W allocations should be O.K. I also add the permission to it by chmod 777, but it still occur segment fault error.

appreciate in advance!

Vincent

I guess the serialport binaries are not correct... can you go into the /root/.node-red directory and run npm rebuild and see if that is successful

[vincentlin_artt]

Thanks, dceejay:
I did, same error occurs.

[dceejay]

I would have expected some output from the rebuild... can you try npm rebuild node-red-node-serialport --verbose ?

or maybe

cd .node-red
npm uninstall node-red-node-serialport
npm install node-red-node-serialport --build-from-source

hi, dceejay:
Here is my result:

1. npm rebuild node-red-node-serialport --verbose
   --> build result: OK and Situation is same, segmentation fault.

2. npm uninstall node-red-node-serialport
   npm install node-red-node-serialport --build-from-source
   --> lots of error came out, attached files are the rebuild logs for those 2 commands.

Please have a look, appreciate again.

Right so you also need the rest of the build tools. Usually gcc and make. There is probably a package that includes them all for openwrt , you can remove them once we get this to work if you need the space back.

[vincentlin_artt]

dear dceejay sir:
I'v tried my best to install the required package for openwrt, there was some progresses, however, there is still errors (
npm ERR! code 1
npm ERR! path /root/.node-red/node_modules/@serialport/bindings-cpp
.......
)
so I can't finish the rebuild process, may you take a look and help...
regards,
Vincent

npm install node-red-node-serialport --build-from-source

Hi, Sir:
I finally finish npm install node-red-node-serialport --build-from-source process and complete from the message.
But ....
How come segmentation fault still happens....
Any idea or hint is much helpful

[dceejay]

the make command seemed to say it couldn't find libpthread - is that installed ?
but yes - you are into territory I have not explored so not sure how I can help much more.

Dear Dceeja:
Many many thanks anyway.
