I'm trying to get the npm package serialport to work with the latest firmware, npm v5.6.0 and node v8.10.0, but to my knowledge there isn't any precompiled binaries for this version. I've tried building from source, but get this output where ld returns with an error /usr/bin/ld: cannot find -lpthread.

BusyBox v1.28.3 () built-in shell (ash)

If I try to

opkg install libpthread

I get

Package libpthread (1.1.19-1) installed in root is up to date.

I have the latest versions of make (4.2.1-2) and gcc version 5.4.0 (OpenWrt GCC 5.4.0) with threadmodel: posix

Did anyone else have luck installing serialport or know how to do it, or do I have to bite the dust and use older firmware to get an older, working package?
