Others have mentioned that lib32z-dev solves the problem  but in general the required packages can be found here   http   source android com source initializing html See  Installing required packages

Another possible cause  You ve passed --static to the linker  but you only have a dynamic version of libz  libz so   but not a version that can be statically linked  libz a

I just encountered this problem and contrary to the accepted solution of  your make files are broken  and  host includes should never be included in a cross compile   The android build includes many host executables used by the SDK to build an android app  In my case the make stopped while building zipalign  which is used to optimize an apk before installing on an android device   Installing lib32z1-dev solved my problem  under Ubuntu you can install it with the following command   sudo apt-get install lib32z1-dev

This will show you clues about why the linker doesn t want the installed library   LD DEBUG all make       I had the same problem in a different context  my system  lib libz so 1 had unsatisfied dependencies on libc because I was trying to relink on a different version of the OS

sudo apt-get install libz-dev in ubuntu

User · Answer

It means you asked it to include the library  libz a  or  libz so  containing a compression package  and although the compiler found some files  none of them was suitable for the build you are using   You either need to change your build parameters or you need to get the correct library installed or you need to specify where the correct library is on the link command line with a -L where it is lib type option

Try one of  those three solution  It must work        sudo apt-get install zlib1g-dev sudo apt-get install libz-dev sudo apt-get install lib32z1-dev   In fact what is missing is not the lz command  but the development files for the zlib library So you should install zlib1g-devlib for ex to get it   For rhel7 like systems the package is zlib-devel

User · Answer

I had the exact same error  and like you  installing zlib1g-dev did not fix it   Installing lib32z1-dev got me past it  I have a 64 bit system and it seems like it wanted the 32 bit library
