From cdc01faed2b92f43a58cb86ff3300af1322cfaf6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jes=C3=BAs=20Legan=C3=A9s=20Combarro=20=22piranna?= Date: Sat, 23 Aug 2014 23:01:06 +0200 Subject: [PATCH] configure: generate a fully statically linked exec Allow to create an executable with no external dynamic libraries, also the ones from the system. This is somewhat dependent of the used C lib, for example glibc has some internal dynamic libraries loaded by itself, but for other ones like eglibc or dietlib, this would produce a true static linked executable. This can be of interest for embebers or resource constraints platforms, but the main reason for this is to allow to use a Javascript file as Linux kernel 'init' on NodeOS.
