[erlang-questions] Building small erlang vm suitable for bundle with app.

[Gustav Simonsson]

Yes, you can remove either the SMP or the non-SMP beam depending on your target architecture.
Also the only things you need to just run Erlang is ERTS and the stdlib and kernel libs.

If you want to reduce the disk usage as much as possibly you can read on methods
in chapter 3.2 and results in chapter 5.1 in the following thesis:

Hi, 


I have not yet spent too much time to investigate how to build 2MB self-sustainable package but systools gives me about 14MB with possible reduction to 7 - 9MB on debian 64bit. 


as an example *.rel package contains following libraries: 

{kernel, "2.14.5"}, 
{stdlib, "1.17.5"}, 
{sasl, "2.1.10"}, 
{crypto, "2.0.4"}, 
{public_key, "0.13"}, 
{ssl, "4.1.6"}, 
{inets, "5.7.1"}, 
{compiler, "4.7.5"}, 
{syntax_tools, "1.6.7.1"}, 
{xmerl, "1.2.10"}, 
{mochiweb, "2.3.0"} 
... 


systools:make_tar($$n, [{erts, code:root_dir()}]) %% do not put any extra dirs here 


most heavy components are VM by itself 

-rwxr-xr-x 1 kolesnik wheel 7.7M Oct 19 20:53 beam 
-rwxr-xr-x 1 kolesnik wheel 9.6M Oct 19 20:53 beam.smp

Hi! 

This is a scrappy half-completed bash script I used to generate 
a small Erlang release. It's something I hope can eventually grow 
into a more general and stable tool for generating Erlang releases. 

It does contain some useful things for reducing the size of an 
Erlang release. 

Also thanks to Adam Lindberg for helping out with it.

Hi, 

I'm quite new to Erlang and this list so I hope I'm posting in the right place? 

I would like to use Erlang code (couchdb) in an Mac OS X app I'm 
developing and I would like to bundle it with my app. Exactly like the 
Mac OS X version of Wings3D is bundling a version of erlang. 

I was wondering if someone kind provide me with some ideas of how to 
compile a smaller version of the Erlang VM without the developing 
tools etc? 

Cheers, 
Albin
