After dealing with the "using namespace std", I receive the following error when compiling json.hpp

    The test suite compiles without problem with g++-7 (Ubuntu 7.1.0-5ubuntu2~14.04) 7.1.0, see https://travis-ci.org/nlohmann/json/jobs/265058071.

    What OS are you using and which exact GCC version?

    Can you provide the source code that yields this error?

    I have commented out most of the lines in which I actually use the library (other than the include, and the field declaration) to narrow down the problem. I use gcc-7 (Ubuntu 7.1.0-5ubuntu2~16.04) 7.1.0

    I copy-pasted your snippet and it compiles with my GCC (Debian 7.1.0-13)

    I can compile the code with g++-7 (Homebrew GCC 7.2.0) 7.2.0.

    Thanks for reporting, but since I cannot reproduce the error, I cannot do much about it.
