Hello.
How better to solve this problem?

Is this still an issue?

[Alex Kontos]

I received this as an issue on Fedora 28. What info would you need to debug?

[Emanuel Duss]

You might not have all the necessary headers installed. I had exactly the same error message.

I could fix it by installing mingw-w64:

# apt install mingw-w64

This provided me the required headers in /usr/i686-w64-mingw32/include/. These belong to the mingw-w64-i686-dev package:

# dpkg -S /usr/i686-w64-mingw32/include/
mingw-w64-i686-dev: /usr/i686-w64-mingw32/include

After this, I was able to use x86_64-w64-mingw32-g++.

Best,
Mänu
