old-style #398

Closed txkgithub closed 5 years ago

txkgithub commented 5 years ago

GitHub issues are for tracking bugs, not for general discussing like a forum.

If you have a general question to ask, send it to mailing list:

muduo-library@googlegroups.com

Or visit: https://groups.google.com/forum/#!forum/muduo-library

When file an issue muduo, please provide a SSCCE: Short, Self Contained, Correct (Compilable), Example.

Also specify the exact environment where the issue occurs:

Linux distro and version? x86 or ARM? 32-bit or 64-bit?

Branch (cpp98/cpp11/cpp17) and version of muduo?

Version of cmake, gcc and boost? (If not from distro.)

Try removing -Werror from CMakeLists.txt if you install boost outside /usr/include.
