+User: ubuntu-devel at lists.ubuntu.com

+
+In Ubuntu, the attached patch was applied to achieve the following:
+
+Hide the warnings, at least for now. This should bring us back to glibc 2.23
+state, AFAICT.
+
+  * Add hide-dlsym-error.patch to hide the errors from dlsym() unless
+    debugging was enabled. This makes builds less noisy and fixes failures
+    in APT test suite with glibc 2.24, which started reporting errors for
+    dlsym()
+
+
+Thanks for considering the patch.
+
+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.
