[android] libz.so.1: cannot open shared object file

I am facing an issue on ubuntu 12.04 as :

/usr/lib/ndk/android-ndk-r8c/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.6/../../../../arm-linux-androideabi/bin/as: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

I tried

sudo apt-get install lib32z1

But it says

Reading package lists... Done Building dependency tree Reading state information... Done lib32z1 is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 610 not upgraded.

Please suggest a solution.

for centos, just zlib didn't solve the problem.I did sudo yum install zlib-devel.i686

After checking to which package does the libz.so.1 belongs (http://packages.ubuntu.com/lucid/i386/zlib1g/filelist) you should try to install zlib1g:

sudo apt-get install zlib1g

As pointed by @E-rich, it may be required to add a :i386 suffix to the package name for the package manager correctly identify it:

sudo apt-get install zlib1g:i386

EDIT (for CentOS or other distro that makes use of yum):

If someone using CentOS (or any other distro that makes use of yum) that may end up reading this question, @syslogic proposed the following solution in the comments:

yum install zlib.i686

or, for 32-bit binaries:

yum install zlib.i386

For Arch Linux, it is pacman -S lib32-zlib from multilib, not zlib.

For Fedora (can be useful for someone)

sudo dnf install zlib-1.2.8-10.fc24.i686 libgcc-6.1.1-2.fc24.i686

I've downloaded these packages:

• libc6-i386
• lib32stdc++6
• lib32gcc1
• lib32ncurses5
• zlib1g

I then unpacked them and added the directories to LD_LIBRARY_PATH in my ~/.bashrc. Just make sure to add proper dirs to the path.

This worked for me

sudo apt-get install libc6-i386 lib32stdc++6 lib32gcc1 lib32ncurses5

sudo apt-get install zlib1g:i386 fixed the Gradle issue on Android 2.1.1 on Xubuntu 16.04.
