Building Basho Erlang / Riak TS on a Raspberry Pi 3
This is unsupported by Basho, but you can build Basho's flavor of Erlang and Riak on Raspberry Pis.

Thanks for the notes, Alex.

On Raspian jessie, I made the following changes to eleveldb and leveldb, but using the versions of eleveldb and leveldb associated with Riak version 2.2.3 (i.e., not develop, as listed above):

Also may want to mention --prefix option to configure, in case you already have an OTP installed via apt-get, but I am sure many folks already know that.

Believe it or not Solr does actually run, though it's pretty slow. You'll also need the following config in your riak.conf to turn off some of the flags expected on 64 bit machines, and to give yz_solr_proc enough time for Solr to start without crapping out. (30s is the default):

search = on
search.solr.jvm_options = -XX:+UseStringCache
search.solr.start_timeout=5m

Hi,

Can you tell me what version of Raspbian this is starting from? Stretch or Jessie?

Is it from a completely fresh install?

Cheers

Gareth

If I follow the steps from above I get the following error message:
make locked-deps...
ERROR:
Cloning into fuse...
Host key verification failed
fatal:Could not read from remote respository

I have little experience and don't know what to do.

Thanks
