needing to keep a new tree of expressions apart for the expressions to get cross-compiled. I changed the whole way of using cross compilation with nixpkgs, which before was done through a simple adapter. Now the adapter became complex, and I've tried to avoid the most obvious recursivities. For example, the fetchurl expression should never be cross-compiled, as the gmp, mpfr, and some others, like some ncurses, perl, ... I made overrided copies of those necessary as perlNoCross, ncursesNoCross, as stdenvNoCross, keeping in mind that the stdenv (capable of cross compilation) is built upon stdenvNoCross using an adapter. So, to cross compile, instead of building using "nixpkgs/default.nix", you should build with your own "myarchiteture.nix", which should have contents like these, for example: import /etc/nixos/nixpkgs/default.nix { crossSystem = { config = "armv5tel-unknown-linux-gnueabi"; bigEndian = false; arch = "arm"; float = "soft"; }; } svn path=/nixpkgs/branches/stdenv-updates/; revision=18398 |
