Missing vector in MSVC

[liurui39660]

Description

When compiled with MSVC (or clang-cl on Windows), the compiler complains vector is not found.

Reproduction

1. Create a C++ source file
2. Paste the following code

#include <mio/mmap.hpp>
int main(int argc, char* argv[]) {}

3. Compile it with MSVC (using Visual Studio, CMake, etc.)

Expected Behavior

The code is compiled successfully.

Actual Behavior

The compiler complains error C2039: 'vector': is not a member of 'std'.

System Info

Windows 10 Pro x64
C++11
mio @ 3f86a95
cmake 3.19.2 (CLion bundled)
cl 19.28.29914 for x64

Possible Solution

For users: Add #include <vector> before #include <mio/mmap.hpp>.

Notes

The complete compilation output, using CMake + Ninja + MSVC in CLion.
