Precautions for installing Plone4.0 in UbuntuServer10.04

For the installation method, see install Plone3.3.5 in javastuserver10.04 and compile "Compressionrequiresthe (missing) zlibmodule" RuntimeError: Compressionrequiresthe (missing) zli.

For the installation method, see install Plone3.3.5 under Ubuntu Server 10.04.

Appears:

"Compression requires the (missing) zlib module"
RuntimeError: Compression requires the (missing) zlib module

.

Solution:

1. Install zlib

To install the latest zlib-1.2.5f, install the Zlib-1.2.1 as follows.

Expected Compilation Time: 0.1 SBU
Expected hard disk space: 1.5 MB

Zlib content
The Zlib package contains the zlib library, which is used by many program compression or decompression functions.

Install the following library files: libz [a, so]

Zlib installation dependency
Zlib depends on: Binutils, Coreutils, GCC, Glibc, Make, Sed.

Install Zlib
Prepare for Zlib Compilation:

./Configure -- prefix =/usr -- shared

NOTE: If CFLAGS is specified in the environment variable, Zlibis cannot compile the shared library normally. If you have specified your own CFLAGS environment variable, add-fPIC to the beginning of CFLGAS and remove this parameter after installation.

Compile the software package:

Make

This software package comes with a test suite to test whether it is correctly compiled. Because Zlib's test suite is fast and harmless, we recommend that you run it. The following command tests the Shared Library:

Make check

Install the Shared Library:

Make install

Compile a non-shared library (static library ):

Make clean
./Configure -- prefix =/usr
Make

The following command tests the static Library:

Make check

Install static Library:

Make install

Modify static library permissions:

Chmod 644/usr/lib/libz.

Installing important programs and library files in the/lib directory is a good habit, especially when/usr is in different partitions. All programs in the/bin or/sbin directory must be in the/lib directory. When the/usr partition cannot be loaded, important programs can still be used.

Therefore, we move the shared zlib library file to the/lib directory:

Mv/usr/lib/libz. so. */lib

The/usr/lib/libz. so symbolic link points to a non-existent file because we moved it. Create a symbolic link pointing to a new location:

Ln-sf.../../lib/libz. so.1/usr/lib/libz. so

2. Install plone4.0
