Full_Name: Patrice Moreaux Version: 2.4.21 OS: Ubuntu Lucid server 32bits URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (193.48.130.254)

Date: 2010/04/06 I installed BerkeleyDB 5.0. Running configure for OpenLDAP 2.4.21 1. BDB 5.0 header is correcty read (major=5, minor=0) 2. However I got then: -------------------------------------------------------- checking if BerkeleyDB version supported by BDB/HDB backends... yes checking for BerkeleyBD link (default)... no configure: error: BDB/HDB: BerkeleyDB not available -------------------------------------------------------- I set the paths for libs and includes. I don't know where is the problem. Could you help me, please? Thank you, regards.
