【转】“/usr/bin/ld: cannot find -lz”

原文网址：http://stackoverflow.com/questions/3373995/usr-bin-ld-cannot-find-lz

I am trying to compile Android source code under Ubuntu 10.04. I get an error saying,

/usr/bin/ld: cannot find -lz
Can you please tell me how can I fix it? What does cannot find -lz mean? Here's the full error message:

external/qemu/Makefile.android:1101: warning: overriding commands for target `external/qemu/android/avd/hw-config-defs.h'

I already have the zlib1g-dev library installed:

zlib1g-dev is already the newest version.

Wow, really? Even though he specifically says less than 4 inches above your comment that he does have it installed? – Justin Buser May 8 '12 at 14:32

@Justin Buser it's obligatory for every stackoverflow question to include a comment that shows that someone read about one sentence of the question and moved on. – magnetar Jun 10 '12 at 13:24

@magnetar Ahhh... that must have been at the end of the FAQ, I didn't actually read the whole thing unfortunately. ;) – Justin Buser Jul 15 '12 at 15:10

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.

It worked here with libz-dev (virtual package for zlib1g-dev) on Kubuntu 12.04 x64. – Qsiris Jan 22 '13 at 16:06

This should be the accepted answer – Speccy Mar 23 '14 at 19:45

Also helped me install/build lxml-3.4.0 for Python via pip on Ubuntu 14.04 LTS/trusty. Thanks! – Marian Sep 15 '14 at 8:07

sudo apt-get install lib32z1-dev #FTW – Sangharsh Dec 11 '14 at 17:51

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 and 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

For x64 just install zlib1g-dev.

sudo apt-get install zlib1g-dev
I don't need all the x86 libs ;)
