Issue MESOS-2991: Compilation Error on Mac OS 10.10.4 with clang 3.5.0
Compiling 0.23.0 (rc1) produces compilation errors on Mac OS 10.10.4 with {{g++}} based on LLVM 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 should support clang 3.5. {code} ../../../../../3rdparty/libprocess/3rdparty/stout/tests/os_tests.cpp:543:25: error: conversion from 'void ()' to 'const Option' is ambiguous Fork(dosetsid, // Great-great-granchild. ^~~~~~~~ ../../../../../3rdparty/libprocess/3rdparty/stout/include/stout/option.hpp:40:3: note: candidate constructor Option(const T& _t) : state(SOME), t(_t) {} ^ ../../../../../3rdparty/libprocess/3rdparty/stout/include/stout/option.hpp:42:3: note: candidate constructor Option(T&& _t) : state(SOME), t(std::move(_t)) {} ^ ../../../../../3rdparty/libprocess/3rdparty/stout/include/stout/option.hpp:45:3: note: candidate constructor [with U = void ()] Option(const U& u) : state(SOME), t(u) {} ^ {code} Compiler version: {code} $ g++ --version Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn) Target: x86_64-apple-darwin14.4.0 Thread model: posix {code}
