I'm new to Linux. I have a copy of Red Hat Enterprise 5 that I am
trying to install libmcrypt on.
I downloaded libmcrypt-2.5.8.tar.gz and extracted it.
I tried to ./configure libmcrypt and got this message:
checking for C++ compiler default output file name... configure:
error: C++ compiler cannot create executables
See `config.log' for more details.

This is odd, because I have not had problems configuring other files.
Complete output from ./configure is at the bottom of this post.

My config.log file is here:
www.osbornewood.com/config.log

After searching the web, I found a couple of things to try:
# g++
bash: g++: command not found
# ./g++
bash: ./g++: No such file or directory
# gcc
gcc: no input files

I'm not sure where to go from here. Any pointers?

Normally, you would download an rpm for libmcrypt from Red Hat, but that
library is not supported on RHEL5.

Did you look in config.log for more details?

P.S.: Looks like you do not have the c compiler installed.

Why not keep it simple? Run yum install to install the package:

$> yum install libmcrypt
.......

Red Hat's already made the rpm package for you, at least I'm sure Fedora
has it so I'd think Enterprise might have it.

$> yum info libmcrypt (as run from Fedora core 6 host)
Loading "installonlyn" plugin
Setting up repositories
Reading repository metadata in from local files
Excluding Packages in global exclude list

Name : libmcrypt

Libmcrypt is a thread-safe library providing a uniform interface
to access several block and stream encryption algorithms.

Good call!
I added a couple of repositories before it would work, but it's
installed now.

I tried to install the PHP extension like so:
> Next, compile the mcrypt dynamic module. From PHP source tree of the current version of PHP running on your server:
# cd ext/mcrypt
# phpize
# aclocal
# ./configure
checking for libmcrypt version... configure: error: libmcrypt version
2.5.6 or greater required.

# yum info libmcrypt
Name : libmcrypt
Arch : i386
Version: 2.4.22

This was the repository that I got the package from:

[freshrpms]
name=Red Hat Linux 9 - Freshrpms
baseurl=http://ayo.freshrpms.net/redhat/9/i386/freshrpms

Is there a better one to use?

Thanks!

Matthew

Doh! My mind disengaged for a moment there.
I did a quick Google for libmcrypt rpm and came up with this site:
dag.wieers.com/rpm/packages/libmcrypt/

It worked like a charm.

On another note, I couldn't figure out how to add it as a repository
to Yum.

I installed rpmforge-release but that didn't seem to add it to /etc/
yum.conf

Any ideas?
