From d2ff818bc56e4f61f953936653f12990a0716737 Mon Sep 17 00:00:00 2001 From: Maxime Hadjinlian Date: Wed, 5 Oct 2016 17:01:23 +0200 Subject: [PATCH] fakeroot: fix spurious message "undefined symbol" Since the glibc 2.24-3, and this commit: https://sourceware.org/git/?p=glibc.git;a=commit;h=80f87443eed17838fe453f1f5406ccf5d3698c25 fakeroot will print spurious message about symbols not being found. [...] dlsym(acl_get_fd): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_fd dlsym(acl_get_file): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_file dlsym(acl_set_fd): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_set_fd dlsym(acl_set_file): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_set_file dlsym(acl_get_fd): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_fd dlsym(acl_get_file): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_file [...] It doesn't seem to impair the behavior of fakeroot, it's simply annoying for the user. Debian (which is the creator of fakeroot) has a patch which is a workaround: simply don't display the message. Note if you wish to bump fakeroot: A new version is available but the release tarball doesn't include the 'configure' and 'Makefile' pre-generated. This means that if we were to bump, the package would need to run its own 'bootstrap' script which will add dependencies to host-{automake,autoconf,...} which would be annoying (since almost every build runs fakeroot).
