4.5. Troubleshooting

This section gives solutions to common Bugzilla installation problems.

4.5.1. DBD::Sponge::db prepare failed

The following error message may appear due to a bug in DBD::mysql (over which the Bugzilla team have no control):

 DBD::Sponge::db prepare failed: Cannot determine NUM_OF_FIELDS at D:/Perl/site/lib/DBD/mysql.pm line 248.
  SV = NULL(0x0) at 0x20fc444
  REFCNT = 1
  FLAGS = (PADBUSY,PADMY)

To fix this, go to <path-to-perl>/lib/DBD/sponge.pm in your Perl installation and replace

 my $numFields;
 if ($attribs->{'NUM_OF_FIELDS'}) {
     $numFields = $attribs->{'NUM_OF_FIELDS'};
 } elsif ($attribs->{'NAME'}) {
     $numFields = @{$attribs->{NAME}};

by

 my $numFields;
 if ($attribs->{'NUM_OF_FIELDS'}) {
     $numFields = $attribs->{'NUM_OF_FIELDS'};
 } elsif ($attribs->{'NAMES'}) {
     $numFields = @{$attribs->{NAMES}};

(note the S added to NAME.)

4.5.2. cannot chdir(/var/spool/mqueue)

If you are installing Bugzilla on SuSE Linux, or some other distributions with "paranoid" security options, it is possible that the checksetup.pl script may fail with the error:
cannot chdir(/var/spool/mqueue): Permission denied

This is because your /var/spool/mqueue directory has a mode of "drwx------". Type chmod 755 /var/spool/mqueue as root to fix this problem.
