Qiyuan Gong commented on YARN-8498:
-----------------------------------
Facing the same 'cleanup' and '__WAIT_STATUS' errors in Fedora 27, when we
tried to build Hadoop with native. However, the same code, the same building
command works well on Ubuntu 16.04 and CentOS 7.
I think this problem is caused by C and C++ code compatibility on high version
gcc (gcc is version 7+ in Ubuntu 18 and Fedora 27, while version 5+ in Ubuntu
16.04 and CentOS 7). According to
[https://gcc.gnu.org/projects/cxx-status.html], gcc 5 and gcc 7 have lots of
difference, such as inline
([https://en.cppreference.com/w/cpp/language/inline]).
Solving this problem requires to make some changes in related C and C++ code,
i.e., 'oom_listener_main.c' and 'oom_listener_test_main.cc', just like what you
have done in this patch. I have tried your patch, it works for me (Fedora 27
with gcc 7.3.1).

> While building this project, I ran into a few compilation errors here. The

> At the very end, during the compilation of the OOM test, it fails again:
