You need to know that it was built against a compatible Kerberos library, a sane Cyrus SASL version, and a working crypto library. The only way to know that is to build it yourself against valid packages, in which case, you don't need to go grubbing through the system looking for them. If you're depending on some OpenLDAP that was packaged by someone else, then you should be asking them to provide a pkg-config file for their package. Installation issues are strictly not our concern, we distribute source code. That should have already been clear from http://www.openldap.org/its/index.cgi/Archive.Build?id=5184 Followup 1. Even if we provided a .pc file, you still have to guess where *that* got installed - was it in /usr, or in /usr/local, or somewhere else? I've certainly never seen pkg-config as a standard component of AIX or Solaris. Is pkg-config even supported on AIX? -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

for Samba we really have some pain to get the right compile and linker flags for different architectures, especially there, where OpenLDAP is not a first-class citizen like on AIX. mozldap offers pkg-config files which we will start to use in Samba soon. It would be great if OpenLDAP would offer a pkg-config file also to not have to make wild guesses which linker/compile flags and which paths to use.

(ITS#7876) LMDB compile issue on AIX 6.1
by fkruchio＠gmail.com 12 Jun '14

12 Jun '14

Full_Name: Frank Kruchio Version: LMDB OS: AIX 6.1 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (203.97.151.51) Looking at cfengine 3.6 deployment on AIX and LMDB is a possible database to use. This is the error I receive when running make. Has anyone managed to compile lmdb on AIX ?

Thanks for the report. This appears to have been broken due to commit 18a07eb7c2dc33372455a6040984cd6b699b41a5 for ITS#7681.

Full_Name: Arne de Bruijn Version: mdb.master a93810c OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (94.210.130.16) MDB_GET_BOTH seems to unexpectedly return success if a data-value before the first data-value for a key is requested. The example program sets 1:b and 1:c and requests 1:a.
