I'm building OpenLDAP on a RHEL 5; I used instructions found at http://www.linux.com/archive/feature/113607.

All went well, until running './configure' for OpenLDAP - the following error was recorded:

*<earlier output snipped>*
checking for gethostbyaddr_r... yes
checking number of arguments of ctime_r... 2
checking number of arguments of gethostbyname_r... 6
checking number of arguments of gethostbyaddr_r... 8
checking db.h usability... yes
checking db.h presence... yes
checking for db.h... yes
checking for Berkeley DB major version in db.h... 5
checking for Berkeley DB minor version in db.h... 1
checking if Berkeley DB version supported by BDB/HDB backends... yes
**checking for Berkeley DB link (default)... no
configure: error: BDB/HDB: BerkeleyDB not available**

I have Googled like a maniac but have been unsuccessful to find a resolution - any tips on areas to explore?

Thanks

do yum install db4-devel

(or just install the prepackaged openldap, yum install openldap-servers openldap-clients

Seems you are using tarball installation, first you should install Berkeley DB. You can find it from oracle website at Oracle Berkeley DB Downloads. Compile and install it.

cd db-4.7.25.NC
. ./dist/configure
make
make install
cd /usr/local/BerkeleyDB.4.7/

This will install BerkeleyDB. Now you need to provide the location to successfully compile OpenLDAP.

export CPPFLAGS="-I/usr/local/BerkeleyDB.4.7/include"
export LDFLAGS="-L/usr/local/BerkeleyDB.4.7/lib -Wl,-R,/usr/local/BerkeleyDB.4.7/lib -Wl,--enable-new-dtags"
# Build OpenLDAP
... 

If you don't set RPATH then you should add LD_LIBRARY_PATH to /etc/profile.

export LD_LIBRARY_PATH="/usr/local/BerkeleyDB.4.7/lib"

After this compile OpenLDAP, let me know if you face any issue.

For CentOS 7, do yum install libdb-devel. libdb4-devel did not work for me.

debian try:

aptitude install libdb5.1 libdb5.1-dev libdb5.1-dbg

apt-get install libdb-dev worked for me in Ubuntu Server.
