<div dir="ltr">I think you are correct that these solutions are rarely needed. As author of NIFPP I see very little traffic at <a href="https://github.com/goertzenator/nifpp">https://github.com/goertzenator/nifpp</a> which gives me the impression that few people use it.<div><span style="line-height:1.5"><br></span></div><div><span style="line-height:1.5">Also there are multiple paths to integration </span><span style="line-height:1.5">(ports vs c-node vs NIFs) so this</span><span style="line-height:1.5"> maybe creates fragmentation and further reduces traction for any one project.

Do I need to jury rig a weird build system to make this thing go, or will it just work with rebar/<a href="http://erlang.mk">erlang.mk</a>? If it's too much hassle to use, then I'll just skip it.

Pretty much all of the "not built in to OTP" ways to connect to other<br>
languages seem to have died, i.e.<br>
<br>
- EPI (C++). Last commit 2009.<br>
- py_interface (Python). Last commit 2014. Freshest of the lot.<br>
- edtk (C). Last release 2007.<br>
- dryverl (C). Last release 2008.<br>
- erlua (Lua). Project page dead. Author's email is dead.<br>
- erlualib (last commit 2010). Github-linked company page dead.<br>
<br>
Can anyone offer some experiences or ideas why?<br>
<br>
Could it be that these types of solutions are rarely needed? Maybe<br>
NIFs are unbeatable for the "narrow interface, no state, high<br>
performance" cases and port programs with hand-rolled interfaces most<br>
of the rest.<br>
