Hi, first of all, my apologies for taking care of your message so late, but it got stuck between tons of spam as you're not subscribed to the list.
We have received reports aobut similar problems in the past. Our solution was to link the drivers against libdbi by default. There is still a switch to toggle this behaviour, but the default has simply been reversed. This is implemented in the current CVS version, and it will be widely available as soon as we dare to release 1.0. regards, Markus Martin Sperl writes: > Hi! > > > > I have found this bug more than a year ago already, but forgot to > mention it on this list. > > Now that rrdtool has gained libdbi-backend support in the latest trunk > version I believe that the need will be higher that this is fixed... > > > > The problem is that when calling dbi_driver_open with a valid driver > (e.g: mysql) it works fine when using the rrdtool binary itself, but > when invoking the same command via the PERL binding for RRDTool it > fails. > > > > The reason is that in this case some symbols cannot get resolved in this > case. > > > > The example output message is: > > [EMAIL PROTECTED] SOURCES]# perl rrdtool.test.pl > > /usr/lib/dbd/libdbdmysql.so: undefined symbol: _dbd_parse_datetime > > libdbi: Failed to load driver: /usr/lib/dbd/libdbdmysql.so > > [EMAIL PROTECTED] SOURCES]# > > > > The only solution that seems to help is recompiling the drivers with > export LDFLAGS="-ldbi" before starting configure. > > > > [EMAIL PROTECTED] SPECS]# ldd /usr/lib/dbd/libdbdmysql.so | grep dbi > > [EMAIL PROTECTED] SPECS]# rpm -Uhv > ../RPMS/i386/libdbi-dbd-mysql-0.8.1a-1.2.2.i386.rpm --force > > Preparing... ########################################### > [100%] > > 1:libdbi-dbd-mysql ########################################### > [100%] > > [EMAIL PROTECTED] SPECS]# ldd /usr/lib/dbd/libdbdmysql.so | grep dbi > > libdbi.so.0 => /usr/lib/libdbi.so.0 (0x002d2000) > > [EMAIL PROTECTED] SPECS]# > > > > [EMAIL PROTECTED] SOURCES]# perl rrdtool.test.pl > > [EMAIL PROTECTED] SOURCES]# > > > > So you may want to incorporate this "patch" that libdbi is linked out of > the box with any future releases of libdbi-drivers... > > > > Cheers, > > Martin > > > > -- > > MARTIN SPERL > Manager, System Engineering > Amdocs Qpass Austria GmbH > > FN 185962 z, Commercial Court Vienna > > Neutorgasse 12/1, 1010 Vienna, Austria > > +43.1.5326464.708 (desk) > +43.676.6688634 (mobile) > +43.1.5326464.300 (fax) > > AMDOCS > CUSTOMER EXPERIENCE SYSTEMS INNOVATION > > > > > This message and the information contained herein is proprietary and > confidential and subject to the Amdocs policy statement, > you may review at http://www.amdocs.com/email_disclaimer.asp > <html xmlns:v="urn:schemas-microsoft-com:vml" > xmlns:o="urn:schemas-microsoft-com:office:office" > xmlns:w="urn:schemas-microsoft-com:office:word" > xmlns:x="urn:schemas-microsoft-com:office:excel" > xmlns:p="urn:schemas-microsoft-com:office:powerpoint" > xmlns:a="urn:schemas-microsoft-com:office:access" > xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882" > xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882" > xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:z="#RowsetSchema" > xmlns:b="urn:schemas-microsoft-com:office:publisher" > xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" > xmlns:c="urn:schemas-microsoft-com:office:component:spreadsheet" > xmlns:odc="urn:schemas-microsoft-com:office:odc" > xmlns:oa="urn:schemas-microsoft-com:office:activation" > xmlns:html="http://www.w3.org/TR/REC-html40";
