However, your need is clear. I've designed a different fix, which requires to set --with-odbc to the preferred sequence of ODBCs to try (iodbc | unixodbc), while the default (auto) tries the original sequence.

(ITS#4735) configure choice of ODBC
by rk＠owen.sj.ca.us 06 Nov '06

06 Nov '06

Full_Name: R.K. Owen Version: HEAD OS: linux URL: ftp://ftp.openldap.org/incoming/rkowen-061106.patch Submission from: (NULL) (66.87.79.68) When using the back-sql with the Oracle XE DB, the Oracle ODBC library libsqora.so.10.1 was designed to be linked against the unixODBC interface library instead of the iODBC interface library. This can be demonstrated by using the unixODBC isql tool which will allow successful interactive querying of the Oracle DB. However, when trying to start up the slapd daemon with 'slapd -d 1' the daemon will quit with an error claiming: Message: [iODBC][Driver Manager] /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib/libsqora.so.10.1: undefined symbol: bcuMsgBoxError The cause for this is that the configure script will first search for iodbc, then odbc, and thus cause slapd to be built against the iodbc library. By adding the -with-odbc option the configure script will allow the administrator to choose which library to use in a flexible way: --with-odbc=iodbc # current default (-liodbc) --with-odbc=odbc # try -lodbc --with-odbc=/usr/lib/libodbc.so.1 # link against the shared object library The changes have been made to the source configure.in file and uploaded as a patch.

Sounds good. env method is best I suppose, but there are others as listed at: http://perldoc.perl.org/perlrun.html#DESCRIPTION Almost finished that cleanup. It's taken a bit longer than expected.

I also don't like hard-wiring "/usr/bin/perl", as the system Perls are rarely up to date. My favourite technique is: #! /usr/bin/env perl -w which finds Perl from $PATH.

(ITS#4733) back-config should populate defaults
by hyc＠OpenLDAP.org 05 Nov '06

05 Nov '06

Full_Name: Howard Chu Version: 2.3/HEAD OS: URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (76.168.84.21) Submitted by: hyc If a minimal LDIF is slapadd'd to create the slapd configuration, any parameters that are not specified on input will take on their default values. However, these defaults will not be present in the config entries and will not be visible upon subsequent slapcat/ldapsearch. It would be nicer if after each entry is loaded from slapd.d and parsed, the entire entry is regenerated internally, with all defaults populated.

It seems you can close this ITS. I followed Howard's advice and started over with a new CVS working dir. Ciao, Michael.

Ok, it seems the build worked with a fresh CVS working dir. You can close this ITS. I'll file another one for make distclean though... Ciao, Michael.
