We have gone through the decision of selecting a proper triplet for x32 with Yocto project already. We are using x86_64-linux-gnunx32 as triplet for x32. This also marks that there is no change in the architecture part of the triplet, and only OS part of the triplet is changed to denote x32 abi support. With this we are building thousands of packages for x32. Nitin -- To UNSUBSCRIBE, email to debian-dpkg-bugs-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
