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

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
