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 message shows up saying that zlib1.dll is missing.
This is the error message
the program can't start because zlib1.dll is missing from your computer
I have tried installing/re-installing with no luck. I don't know what's the problem here?
Can anyone please help me with this problem as I have some homework that I need to do but I can't without the compiler.
Thanks.
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.
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.
Had same problem here, I've just used mingw-get install mingw32-libzat the cmd and it worked.
