Answer 1

Had same problem here, I've just used mingw-get install mingw32-libzat the cmd and it worked.

Answer 2

From the MinGW getting started; an automated GUI installer assistant, or use mingw-get, is available (installed as "MinGW Installation Manager") and can be used to install additional libraries and manage dependencies. For the missing zlib libraries, add the mingw32-libz libraries as required.

It seems to have been an issue previously here on super user. It seems you may be able to get them directly from the zlib website. Open Babel has some info on it being required to be copied afterwards (together with some other dlls).

Alternatives include using the mingw-w64 distros from nuwen or mingw-builds. I've never had any issue getting these up and going. They also support x64 builds.

Answer 3

I had this same problem, but fixed it like this:

1. I ran the MinGW Installation Manager (e.g. C:\MinGW\libexec\mingw-get\guimain.exe).

2. I navigated to All Packages -> MinGW -> MinGW Libraries.

3. I checked the boxes next to mingw32-libz (dev & dll).

   

4. I went to Installation -> Apply Changes.

Now everything worked properly.
