Eelco Dolstra a2cbc77e4f Only show/build a package on the platforms listed in meta.platforms ... The function ‘mkDerivation’ now checks whether the current platform type is included in a package's meta.platform field. If not, it throws an exception: $ nix-build -A linux --argstr system x86_64-darwin error: user-thrown exception: the package ‘linux-3.10.15’ is not supported on ‘x86_64-darwin’ These packages also no longer show up in ‘nix-env -qa’ output. This means, for instance, that the number of packages shown on x86_64-freebsd has dropped from 9268 to 4764. Since meta.platforms was also used to prevent Hydra from building some packages, there now is a new attribute meta.hydraPlatforms listing the platforms on which Hydra should build the package (which defaults to meta.platforms).		2013-11-05 00:06:10 +01:00
