Package: libruby2.7 Version: 2.7.1-3 Tags: patch I've looked into cross building ruby extensions again. With help from Antonio Terceiro and Chris Hofstaedtler, we figured that we likely need three changes to make this work:
* gem2deb should pull a native ruby. Otherwise running ruby fails. * $something should cause ruby to use the host's rbconfig.rb. * The build should use cross compilers. The last of these is a problem since the compilers used for building extensions are those listed in rbconfig.rb. It currently lists CC -> gcc and CXX -> g++. Since these are unqualified, they're unsuitable for cross building. If rbconfig.rb were mapping these to triplet-prefixed build tools (which work both natively and during cross builds) and we were solving the other aspects, we could likely cross build simple ruby extensions. So here goes the patch that makes rbconfig.rb contain triplet-prefixed tools. The hard part of making the build use the correct rbconfig.rb is not yet solved. Helmut
