I wanted to install Kaldi in Cygwin environment.

I have installed all the necessary dependencies and packages.

When I run check_dependencies, I am getting error like,

check_dependencies.sh: zlib is not installed

./check_dependencies.sh: The following prerequisites are missing; install them first: zlib1g-d

But this issue seems to be persisting despite the fact, I have selected all dependencies that contain Zlib.

Can anyone please help me, why this is happening?

I have searched the internet and this forum. But nothing seems to be satisfying.

Kindly please help me with this issue.

  • Never ever try to use cygwin for recent thing. Install Linux at least in virtual machines. – Nikolay Shmyrev Feb 03 '20 at 06:19
  • @nicolay-shmyrev Please be useful. Not every one agrees with your opinion nor can install a virtual machine on the computer – matzeri Feb 03 '20 at 06:49

    The script seems to have some assumption about the system that do not fit with Cygwin: it does not recognize g++, an that is strange also for a Linux system. It requires the MKL library, on Cygwin Lapack and Openblas are available. The `zlib` header and import library are in the package `zlib-devel` but I suspect the script is looking for a different method to find packages and it is not looking at the files itself. `zlib1g-dev` is surely not the name of a package in Cygwin, but it is in `Debian` and derived Distro. Cygwin package names are more in line with `Fedora` style. – matzeri Feb 03 '20 at 07:03
  • Yeah, most likely you need to install the `zlib-devel` package. Without seeing what this custom `check_dependencies.sh` script is doing it's hard to say much else. – Iguananaut Feb 04 '20 at 17:26

I had a similar problem but installing Pillow under cygwin. As it was mentioned in the comments above by Iguananaut, the development package zlib-devel is needed. So, I just went to cygwin setup program, selected this package and installed it. The tried again to install Pillow in the cygwin terminal. The problem was solved.
