How to install POSIX REGEX software

premkarat · 07-08-2009, 07:19 AM

I am trying to install openLDAP and find that POSIX REGEX is a required package to be installed before installing openLDAP.

Can anyone let me know which package I need to install for this?

Any help is much appreciated!!

Just to add, am using CentOS 5.3
Cheers,
Prem

If you install using the package manager, then the dependencies will be handled automatically.

I've installed openLDAP on several machines and I've never seen a package called "POSIX REGEX". Google finds this name in some PHP articles, plus what appears to be a Perl module. At a glance, some of them look like Regex checker utilities. I can't imagine why this would be needed for openLDAP.

Please tell us how you are installing openLDAP and post the exact error messages.

I am not sure what the package name of that sofware is. But this is what "ReadMe" shows

"REQUIRED SOFTWARE
Building OpenLDAP Software requires a number of software packages
to be preinstalled. Additional information regarding prerequisite
software can be found in the OpenLDAP Administrator's Guide.

Base system (libraries and tools):
Standard C compiler (required)
Cyrus SASL 2.1.21+ (recommended)
OpenSSL 0.9.7+ (recommended)
Reentrant POSIX REGEX software (required)"

Have attached the readme for your reference.

So as you can see it shows "POSIX REGEX" as a required software.

Also there isn't any problem I faced during the installation. Since I coudln't find any detailed info (just like you did in google) I was concerned if that would cause any problem during or post installation.

Installation is successful but I am not sure what are the problems likely to pop up if REGEX package is not included.

Basic LDAP operation is successful though.

I guess one could read "Reentrant POSIX REGEX software" to mean a generic TYPE of SW---and not a specific package. But, if OpenLDAP is working, then all is well, n'est-ce pas?

Out of curiousity, why did you have to compile it? Doesn't your repository have OpenLDAP (or something equivalent)? On this system (Mepis) it's called "ldap-utils".

No I build this system initially as a standalone one (only for my personal use) rather than as a server. Now this is slowly changing to play a server role (thanks to the recession).

If I may ask you, since I am new to open LDAP, I am trying to understand what role does this Indices play in "Slapd.conf". ("#Indices to maintain for this database")

If you can help me with a good link that speaks about slap.conf in detail (for novices) it would be really helpful.

It looks like "slapd.conf" relates to an LDAP server. I have no experience with this, but Google produces lots of hits using "slapd.conf".
