CentOS 4 - Zlib upgrade HowTo

[cryptic]

As there are quite a few people on here with CentOS boxes with an older zlib (1.2.1x), this quick and simple HowTO will show you how to create an rpm to upgrade zlib.

First, get gcc if you don't have it already:
'yum install gcc'

Next, you will need rpm-build:
'yum install rpm-build'

Now, grab the source rpm for zlib 1.2.3 from the Fedora 5 repos:
'wget ftp://chuck.ucs.indiana.edu/pub/array2/linux/fedora/linux/core/5/source/SRPMS/zlib-1.2.3-1.2.1.src.rpm'

Build the rpm with 'rpmbuild --rebuild zlib-1.2.3-1.2.1.src.rpm'

Now upgrade with the newly created rpms (zlib and zlib-devel):
'rpm -Uhv /usr/src/redhat/RPMS/i386/zlib-*1.2.3-1.2.1.i386.rpm'

Done.
# rpm -q zlib
zlib-1.2.3-1.2.1

Thanks for the howto. I moved your post to the Tips & Tricks forum

Hello,

wget without option doesn't work... I must use the option: --passive-ftp

Perhaps it could help somebody...

Thanks for the info edouardj, but I still can just "wget $file" without issue.

This is with GNU wget v1.10.2

GNU wget v 1.10.2 with centos 4.4 Final (uptodate) ...

but I live in France... Bye

This is caused by your firewall. For some people (with another firewall) it works without --passive-ftp, and some others have to use it.

Sorry to bring this topic back up, but while it was asked, I have another question about zlib.

Does anyone know if zlib 1.1.4 has a limitation of 2GB? The company I'm with handing me this 10year old code and says that zlib may have a 2GB limit.. I've searched all over and the newest version I know has a 4GB depending on how it's compiled. But can't find anything on the older version.

I'm not sure, but the problem might as well be caused by using a 32bit system.
