lsyncd on an x86_64 Synology NAS

[CMOS Orchestra]

I've tried to post on serverfault, but I'm not getting much traction..

https://serverfault.com/questions/977866/lsyncd-on-an-x86-64-synology-nas

lsyncd isn't available as a package on a Synology NAS.

~# opkg install lsyncd

Unknown package 'lsyncd'.

Collected errors:

 * opkg_install_cmd: Cannot install package lsyncd.

So I'm trying to compile it but I run into errors on the `lua` side as I'm unable to generate the `.so` shared library objects.

Concurrently, `lsyncd` is at the center of the "High Availability" (HA) app on the latest DSM from Synology: 

/usr/syno/etc/synoha/lsyncd

/usr/local/bin/lsyncd

/usr/local/packages/@appstore/HighAvailability/etc/lsyncd

/usr/local/packages/@appstore/HighAvailability/usr/bin/lsyncd

Also, because of `iNotify` and `fsevents`, `lsyncd` "needs to run on the system where the files are located physically":

Is there any chance anybody can help with taking control of `lsyncd` on Synology NASes?

Thanks.
