Package: iputils Version: 3:20101006-1 Severity: wishlist Tags: patch User: [email protected] Usertags: origin-ubuntu ubuntu-patch precise
The attached patch makes it possible to cross-build iputils given a suitable cross-building environment. Please see: https://bugs.launchpad.net/ubuntu/+source/iputils/+bug/872370 The small upstream patch should be reasonably maintainable, but I think it should also be reasonably portable if you want to forward it on to upstream. As far as I can tell there is no way to cause -lfoo in a make prerequisite to do the right thing for cross-building. * Support cross-building (thanks to Wookey <[email protected]> and Harry Liebel; LP: #872370). diff -Nru iputils-20101006/debian/patches/cross-building.diff iputils-20101006/debian/patches/cross-building.diff --- iputils-20101006/debian/patches/cross-building.diff 1970-01-01 01:00:00.000000000 +0100 +++ iputils-20101006/debian/patches/cross-building.diff 2011-11-08 13:15:29.000000000 +0000 @@ -0,0 +1,27 @@ +Description: Find libraries using gcc rather than make + make's facility of using -lfoo as a prerequisite doesn't work with + cross-building.
