------------------------------------------
Summary: Compilation Error on Mac OS 10.10.4 with clang 3.5.0
Key: MESOS-2991
URL: https://issues.apache.org/jira/browse/MESOS-2991
Project: Mesos
Issue Type: Bug
Components: stout, test
Affects Versions: 0.23.0
Reporter: Alexander Rukletsov
Compiling 0.23.0 (rc1) gives me a compilation errors on Mac with clang 3.5. It
looks like the issue was introduced in
a5640ad813e6256b548fca068f04fd9fa3a03eda, https://reviews.apache.org/r/32838.
In contrast to the commit message, compiling the rc with gcc4.4 on CentOS
worked fine for me.
According to 0.23 release notes and MESOS-2604, we support clang 3.5.
