Problem
Under Ubuntu 10.04, I’m attempting to compile Android source code. I get an error message that says,
Could you please tell me how I can resolve this? What does -lz indicate when it says “cannot find”? The complete error message is as follows:
external/qemu/Makefile.android:1101: warning: overriding commands for target `external/qemu/android/avd/hw-config-defs.h'
external/qemu/Makefile.android:933: warning: ignoring old commands for target `external/qemu/android/avd/hw-config-defs.h'

And here’s what my GCC version produced:
scheung@scheung-virtual-box:/media/EXTDIV/mydroid$ gcc --version

The zlib1g-dev library is already installed:
$ sudo apt-get install zlib1g-dev

zlib1g-dev is already the newest version.
(I learned this from this website.)

I had the same problem as you, and adding zlib1g-dev did not help. I was able to get over issue by installing lib32z1-dev. I have a 64-bit system, however it appears that the 32-bit DLL was required.

Install zlib1g-dev for x64.
sudo apt-get install zlib1g-dev
I don’t require all of the x86 libraries;)

In Ubuntu, use sudo apt-get install libz-dev.

I just ran into this issue, and contrary to the commonly recognized solutions of “your make files are faulty” and “host includes should never be used in a cross compilation,” I came up with my own solution.
Many host executables utilized by the SDK to develop an android app are included in the android build. Make stopped constructing zipalign in my case, which is needed to optimize an apk before installing it on an Android device.
My problem was solved by installing lib32z1-dev, which you can do with the following line on Ubuntu:
sudo apt-get install lib32z1-dev

I had the same problem, but installing zlib-devel fixed it. Type the command and install the zlib package.
On linux:
sudo apt-get install zlib*
On Centos:
sudo yum install zlib*
