Makefile error (libz.so.1: cannot open shared object file)

[gb127]

Hi,

Does anyone know how do solve the following error during makefile processing?What does it means?

Makefile output
/sbin/mkfs.jffs2: error while loading shared libraries: libz.so.1:cannot open shared object file : No such file or directory
make[1] :***[install] Error 127
make[1] : Leaving directory
make:*** [system] Error 2

-----------------------------------------------------
The error occurred after this command
rm -f $(LIB_MOD)/modules.*
/sbin/depmod -b $(RAMDISK_DIR) -F ../$(LINUX)/System.map -A $(KERNELRELEASE)
@$(STRIP) ramdisk/lib/iptables/*
@$(STRIP) ramdisk/lib/pppd/*
@$(STRIP) ramdisk/usr/sbin/*
@$(STRIP) ramdisk/sbin/iptables

This makefile is used for arm gcc compiling in host development(fedora15 64bits).Any help will be appreciate.Thanks.

I think that you are being told that the shared object file libz.so.1 is missing on the build system. Try

su -c 'yum install zlib-devel'

and see if that fixes it.

Thanks for reply. After I tried the command , the same error is still occur. Also, how do I check whether the package is installed as I'm just a new Linux platform user?

[marriedto51]

To check if a package is installed, use "rpm -q", so here I would try

rpm -q zlib zlib-devel

One thing to watch for if you are using the 64-bit version is the end of the package name: ".i686" signifies the 32-bit libraries, and ".x86_64" is for the 64-bit ones.

To look for a file quickly:

locate libz.so.1

Also, it may have been damaged somewhere (protection, security label...)

Sometimes such problems can be cleared up with a reinstall. You might try "yum reinstall zlib-devel"

Hi jpollard,
It still not working after re-installation "zlib-devel".

Hi marriedto51,
I have tried both of commands "rpm -q zlib zlib-devel" and "locate libz.so.1".It shows
1) zlib - 1.2.5-5.fc15.x86_64
zlib-devel - 1.2.5-5.fc15.x86_64
2) /lib64/libz.so.1

It seems I have already installed the package,right?
Have any other solution?Thanks for helping.

[marriedto51]

Yes, that looks like the packages are installed.

I think to get any further will need more information on what you are trying to build.

Just one further thought: do you need the 32-bit library? Try

su -c 'yum install zlib.i686'
