glibc started to return errors from dlerror() for dlsym() lookup failures which results in a lot of messages from fakeroot like dlsym(acl_get_fd): staging_dir/host/lib/libfakeroot.so: undefined symbol: acl_get_fd dlsym(acl_get_file): staging_dir/host/lib/libfakeroot.so: undefined symbol: acl_get_file dlsym(acl_set_fd): staging_dir/host/lib/libfakeroot.so: undefined symbol: acl_set_fd when building OpenWrt using a recent glibc. Use the patch from the upstream Debian package to silence these messages. Link: https://bugs.debian.org/830912 Fixes: FS#3393 Signed-off-by: Sven Wegener <sven.wegener@stealer.net>

Description: Hide error from dlsym()
|
|
dlsym(), starting in glibc 2.24 actually reports errors. In our case,
|
|
we try to get ACL functions which are not in the glibc. This causes
|
|
failures in test suites, so hide those messages for non-debugging
|
|
purposes for now. It also makes the build logs annoying to read.
