Package: user-mode-linux
Version: 2.6.32-1um-3
Severity: wishlist
Tags: patch
Hi there,
Thanks for packaging user-mode-linux in Debian! We were copying the
package automatically in Ubuntu unmodified and it was failing to build
due to Ubuntu changes to dpkg-dev to set
LDFLAGS=-Wl,-Bsymbolic-functions by default (in dpkg-buildpackage).
Usually, kernel packages have very different constraints on
CFLAGS/LDFLAGS than userspace packages, so in the Ubuntu kernel
packages we "unexport CFLAGS LDFLAGS" in the rules.
I fixed the amd64 build of user-mode-linux by applying the attached
patch which will strip -Wl,-Bsymbolic-functions from LDFLAGS, would you
mind applying that to the Debian package? Or perhaps use the unexport
recipe, whatever you find best.
Thanks!
