On a related note, Rcpp, used extensively in the R package, is GPLv2/GPLv3 licensed.
I'm not aware of any other R package available that supports R<->C++. https://www.apache.org/legal/resolved.html#category-x https://cran.r-project.org/web/packages/Rcpp/index.html _____________________________ From: Henri Yandell <bay...@apache.org<mailto:bay...@apache.org>> Sent: Wednesday, July 5, 2017 11:23 PM Subject: ZeroMQ licensing in Apache MXNet To: <gene...@incubator.apache.org<mailto:gene...@incubator.apache.org>> Cc: <dev@mxnet.incubator.apache.org<mailto:dev@mxnet.incubator.apache.org>> One of the items that is on the list to do before releasing Apache MXNet is removing ZeroMQ from the codebase/dependencies. ZeroMQ is licensed under the LGPL 3.0 with an exception for static compiling. They have long been interested in relicensing to MPL 2.0, but haven't made much progress, though they did relicense JeroMQ (Java wrapper/implementaiton) last year. In the last few months they've made a lot of progress towards relicensing: https://github.com/zeromq/libzmq/tree/master/RELICENSE I'd like to ask on legal-discuss@ for an exception (one year?) to continue using ZeroMQ, with prominent documentation, in MXNet given the trend towards MPL 2.0. Any concerns before I do so? Thanks, Hen
