Berkeley DB mismatch error while configuring LDAP
berkeley-db, linux, openldap, redhat
Solution
Now the configuration is working fine. I had to export the library path for Berkeley DB properly:
export LD_LIBRARY_PATH="/root/db-6.0.20/build_unix/.libs"
Edit :
The directory `build_unix/.libs` contains the necessary libs for OpenLDAP but also lots of other files produced during the Berkeley installation. I rather suggest to use the destination Berkeley lib directory which is created during the installation (it should be equal to PREFIX/lib), because you would remove/update your Berkeley source directory one day, breaking OpenLDAP runtime (see the end of my edit)
You can either export the LD_LIBRARY_PATH variable, or set it only at the configure time of OpenLDAP, this way :
LD_LIBRARY_PATH="/root/db-6.0.20.installed/lib" ./configure
Usually there would be other configuration options, I am omitting them here.
Once installed correctly, OpenLDAP may still fail to start with the following error message in the log :
5d34473d bdb_back_initialize: BDB library version mismatch: expected Berkeley DB 5.3.28: (September 9, 2013), got Berkeley DB 5.3.21: (May 11, 2012)
To solve this issue, the solution is again to force the LD_LIBRARY_PATH variable, this time in the startup script (wherever is yours, /etc/init.d/openldap for example). As we are talking about the runtime, it's important here to note we shouldn't call the `build_unix/.libs` directory which is considered temporary, but the created `/lib` directory.
Problem
I'm configuring OPENLDAP 2.4.35. on Redhat Linux, I have already installed Berkley DB 4.8.30 as a prerequisite. I also checked the version compatibility from OPENLDAP's README file, which says: ``` SLAPD: BDB and HDB backends require Oracle Berkeley DB 4.4 - 4.8, or 5.0 - 5.1. It is highly recommended to apply the patches from Oracle for a given release. ``` Still I'm getting this error: ``` checking db.h usability... yes checking db.h presence... yes checking for db.h... yes checking for Berkeley DB major version in db.h... 4 checking for Berkeley DB minor version in db.h... 8 checking if Berkeley DB version supported by BDB/HDB backends... yes checking for Berkeley DB link (-ldb-4.8)... yes *checking for Berkeley DB library and header version match... no configure: error: Berkeley DB version mismatch* ``` Kindly help
