Mnesia database extension
« on: February 03, 2013, 09:01:26 PM »
Has anyone done an extension for the Mnesia database. I am playing with Erlang on multiple TinyCore virtual machines and want to use Mnesia as a memory resident distributed database.

It has some unique capabilities that appear to support a distributed memory model which is part of my (formative) AI research.

Thanks and keep up the great work.

which architecture are you looking for this on - core/core64, corepure64, arm?

Core would be fine. There doesn't appear to be a core64 version of Erlang but it would be truly excellent if both Erlang and Mnesia were available in Core64.

Thanks.

the version of erlang in the x86 repo will work on both core/core64 (it is 32-bit).

I thought mnesia was included with erlang?

My understanding is that its part of the OTP (Open Telecoms Platform) extensions.

I assumed Erlang32 would work in Core64. I was dreaming of an Erlang64 and Mnesia64 combination. I've been in this game far to long (obviously).

For clarity:

erlang (in repo) will work with core and core64

a 64bit version (not in repo) would work with corepure64

does erlang need unixodbc and wxwidgets (gtk2) to work with mnesia?

I don't believe so. It is a database in an Erlang package.

I haven't used it yet so I am unsure of all the intricacies.

I'll try and get it running native on my iMac and update the question after that.

Thanks for the help.

erlang built with openssl-1.0.0 and ncurses, but without odbc and wxwidgets posted for corepure64

It looks like mnesia is included - I've no idea how to divide the extension up, so posted as one huge extension...

Let me know how you get on
