[SOLVED] libz.so.1 is missing

michanux · 03-02-2015, 12:36 PM

Hello
from debian root I "chroot" to LFS root.

"make INSTALL_HDR_PATH=dest headers_install"
breaks with the following message:

Code:

  CHK     include/generated/uapi/linux/version.h
/bin/sh: cmp: command not found
  UPD     include/generated/uapi/linux/version.h
  HOSTCC  scripts/basic/fixdep
gcc: error trying to exec 'as': execvp: No such file or directory
scripts/Makefile.host:118: recipe for target 'scripts/basic/fixdep' failed
make[1]: *** [scripts/basic/fixdep] Error 1
Makefile:454: recipe for target 'scripts_basic' failed
make: *** [scripts_basic] Error 2

"as" is present at "/tools/bin/as" but not executable. So I inspected its libraries. "libz.so.1" is missing.
In which step this should be installed ?

Chapter? Host? Other information?

libz.so.1 is part of zlib package.

Interesting, your as file (from binutils pass 2 I guess) is linked against libz.so.1 frm the zlib package.
However, in your temporary build system you do not have zlib installed.
Does this mean that you linked binutils to your base system instead of to the temporary tools?

Also: always start with the first error which is that cmp is missing.
It should have been provided by diffutils.

The system is linked to the temporary tools. Linking to wheezy all things run well.

Or did I misunderstanding the chapter about "paket management".
http://www.linuxfromscratch.org/lfs/...06/pkgmgt.html
Thought this has to influence in building the system ?

The packet management only starts to play a role from chapter 6 onwards.
The problem seems to be the linking of your as command.
Can you check for the other binutils (in the /tools directory) programs whether they are linked to the right libraries using ldd?
This needs to be done when you are in the /tools chroot.
A list of files is found at http://www.linuxfromscratch.org/lfs/...tents-binutils

If there is a problem with the libraries, I would recommend rebuilding binutils pass 2 and hoping this keeps the rest intact.

Good luck

This was a good advice. Thank you.
