Packaging C++ library into a Rails application for Heroku use

Question

asked the next thing from Heroku support the other day:

I have an app that will require a client library written in C++. I have doubts can that be done with Heroku. Is it possible at all, any alternatives how can a C++ library be installed and used by an app with Heroku?

And I got the next answer:

We currently don't have a good way to do this. You'll need to figure out how to package into your app and compile static x64 binaries into the repo.

I haven't done that before. Does anyone have any good pointers how package a C++ library into a Rails app so it can be used with Heroku?

Thanks.

Answer 1

To wrap the C++ library in Ruby, you want Rb++.

Alternately, you can wrap the C++ library in C and then wrap that with Ruby-FFI.

I'm not sure what, if anything, one can do to get the native extensions compiled on Heroku. I'd contact their support and ask.
