I have just started to learn C++ for school, and I\'m trying to download the compiler MinGW to compile my source code. However, every time I try to compile a program an error me
I had this same problem, but fixed it like this:
I ran the MinGW Installation Manager (e.g. C:\MinGW\libexec\mingw-get\guimain.exe).
I navigated to All Packages -> MinGW -> MinGW Libraries.
I checked the boxes next to mingw32-libz (dev & dll).

I went to Installation -> Apply Changes.
Now everything worked properly.
