• Describe what you want to achieve.
  src/../include/json.hpp:13704:61: error: ‘__int64’ was not declared in this scope
  std::memmove(buf + 2, buf + 1, static_cast<size_t>((__int64)k - 1));
• Describe what you tried.
  Try to compile de json hpp in linux.
• Describe which system (OS, compiler) you are using.
  g++ 7.04
  Linux, (works fine in windows)
• Describe which version of the library you are using (release version, develop branch).

Which version are you using? In the develop branch, the code does not contain __int64, and the lines with memmove are the following:

std::memmove(buf + (static_cast<size_t>(n) + 1), buf + n, static_cast<size_t>(k) - static_cast<size_t>(n));
std::memmove(buf + (2 + static_cast<size_t>(-n)), buf, static_cast<size_t>(k));
std::memmove(buf + 2, buf + 1, static_cast<size_t>(k) - 1);

I am using single_include/json.hpp from develop.
I have notice now the master branch.
Should I take the master code instead of ?

[nlohmann]

In any case, the code does not contain __int64. Can you please check whether you included some headers before json.hpp which may re-define std::int64_t or the like?

[M-Tonin]

You are right, for same reason the code I had got had this "__int64". But it doesn't really exist. I can't say what happened. Sorry and thanks!
