Hi, are you using a C++11 compliant compiler? emplace is part of the C++11 standard library.

I am using gcc 4.7 so I guess It does not support C++11. But, when I use intel compiler (2015), the same error happened. It is so strange.

Did you use -std=c++11

I noticed on the compiler webpage

https://software.intel.com/en-us/articles/c0x-features-supported-by-intel-c-compiler

1. 1: * Full C++11 support requires gcc 4.8 environment or newer on Linux

To be on safe side, please try g++ version higher than 4.8.2 with -std=c++11.

With gcc 4.7, I did use -std=c++11, but could not overcome "emplace" error. I'll install new version of gcc and try again. Thanks so much.

[junyang4711]

gcc 4.7 supports some but many features of c++11 for which you will continually see more errors of compiling. Newer version shall solve the problem.
