As written earlier, a patch for portage exists already (just the diff between multilib and master branch of portage). Now, in addition, a GLEP draft for cross-compile support in multilib-portage.

This may be true, but as you may have seen afterwards, beside the responses to my mail about planned council asking, there have not been any further responses, so the relatively short time since my mail doesnt seem like the reason for missing responses.

See attached GLEP draft.

There is an important difference between my cross-compile support for multilib profiles and crossdev: My suggestion works with the default toolchain, which itself is able to cross-compile for other targets (like the amd64/multilib gcc is able to create 32bit libs), while crossdev is using a different toolchain for the targets. Of course, if someone from crossdev maintainers wants to comment, he is free to do so. -- Thomas Sachau Gentoo Linux Developer
