Igor Morozov created MESOS-6809:
-----------------------------------
Summary: libprocess's namespace "unix" conflicts with some
preprocessor directives in gcc compiler
Key: MESOS-6809
URL: https://issues.apache.org/jira/browse/MESOS-6809
Project: Mesos
Issue Type: Bug
Components: libprocess
Affects Versions: 1.2.0
Reporter: Igor Morozov
Priority: Minor
libprocess uses namespace unix like this for example in address.hpp:
#ifndef __WINDOWS__
namespace unix {
class Address;
} // namespace unix {
#endif // __WINDOWS__
GCC defines preprocessor directives with the same name:
gcc -dM -E -std=gnu++11 - < /dev/null | grep unix
#define __unix__ 1
#define __unix 1
#define unix 1
that is causing namespace conflicts and compilation error.
g++ --version
g++ (Debian 4.9.2-10) 4.9.2

the fix is to change -std=gnu++11 to -std=c++11 whenever possible
