Compiler support errors are inconvenient

[1Hyena]

Instead of whitelisting compilers you should blacklist them. What's the point of compiler whitelisting anyway? Shouldn't the code be portable in the first place?
This is my compiler:
g++ (Ubuntu 4.8.5-2ubuntu1~14.04.1) 4.8.5

I received the compiler error, I couldn't easily upgrade my compiler because seems that my system uses 4.8.5 by default and getting around it would have required me to change the Makefile of my project which I didn't want to do (to specifically call g++4.9 instead of just g++). So I changed the header file to this

// exclude unsupported compilers
#if defined(__clang__)
    #if (__clang_major__ * 10000 + __clang_minor__ * 100 + __clang_patchlevel__) < 30400
        #error "unsupported Clang version - see https://github.com/nlohmann/json#supported-compilers"
    #endif
#elif defined(__GNUC__)
    #if (__GNUC__ * 10000 + __GNUC_MINOR__ * 100 + __GNUC_PATCHLEVEL__) < 40800
        #error "unsupported GCC version - see https://github.com/nlohmann/json#supported-compilers"
    #endif
#endif

and everything compiled just fine, I ran my program and it works. Not sure what the big issue is. Why wouldn't nlohmann::json compile correctly with g++ 4.8.5 ???

For the record, I use linux mint 17.1 (is it really obsolete already? I don't think so).

From the page mentioned in the error message:

GCC 4.8 does not work because of two bugs (55817 and 57824) in the C++11 support. Note there is a pull request to fix some of the issues.

The test suite fails to compile with GCC 4.8. Whereas a subset of the features may work, I do not want to provide support for this compiler version.

oh ok, C++11 related issues I guess I should really upgrade my compiler then :D
