installing mms on synology nas: error while loading shared libraries: libfl.so.2: cannot open shared object file: No such file or directory

[mluerig]

hi, I'm trying to install mms on my synology nas via ssh. I install make and gcc via ipkg. then I cloned the repo, and ran npm intall inside the folder, but then I got this error:

mluerig@ml-nas:~/mms$ npm install

Have you tried to pre-built binaries from https://www.mediamonkey.com/forum/viewtopic.php?f=31&t=90809?

Building on Synology is tricky, we actually use cross-compilation there. If you are interested, you can check out scripts/build-armv7-synology.js and related code to compile the binaries yourself.

[mluerig]

thanks! so, I would compile it on a desktop machine and then install it my nas?

[jirihajek]

Yes, unless you want to just download and use the compiled builds, you can run npm run build-armv7-synology or npm run build-armv8-synology to compile sqlite. The scripts are there to prepare the whole packages (custom node build for pkg script), but you can only extract sqlite if you want.

Docker is needed, compilation tested on Windows, but should probably work in other environments as well.

[mluerig]

I want to give the prebuilt binaries a try first, but I am not sure how I would "Extract the files to a directory and run mms." run, exactly how? and can I run it from DSM?

[jirihajek]

We don't have a DSM package yet, so a terminal access is needed (probably, not sure whether there's another solution). The archive can be then extracted using tar and executed as './mms'.

[mluerig]

I have tried what you suggested, i.e., download the binaries, extracted them to home, and running "./mms" - but this doesn't do anything. there is probably some misunderstanding from my side. Here is the console output, mms is a folder containing the tar.gz contents

´drwxrwxrwx  1 mluerig users                 66 Jul  7 17:02 mms
-rw-r--r--  1 mluerig users           48608800 Jan 13  2021 MMS-armv7-0.3.2.tar.gz

mluerig@ml-nas:~$ ./mms
-sh: ./mms: Is a directory
mluerig@ml-nas:~$ cd mms
mluerig@ml-nas:~/mms$ ./mms

Sorry, for the late answer. I'm not sure why the prebuilt binary can't be started. However, I'd recommend to return to the original attempt, i.e. to run npm install (after updating the repo). There has been a lot of improvements in better-sqlite3 and so I hope it might work right out of the box now. If not, I could send you its armv7 build then. Thanks!
