( #3333=superdoc: print w/replies, xml ) Need Help??

To debug an issue, I need to install an older DBI and DBD::Oracle.

I thought I'd done everything correctly (using PREFIX after the perl MakeFile.PL call, but when I try to run the app that is using the new libraries (using a BEGIN block to add the custom lib dirs), I get this error:

DBD::Oracle object version 1.74 does not match bootstrap parameter 1.64 at .../DynaLoader.pm line 223

Dumping @INC in DynaLoader, I see that the custom lib dirs aren't in it. A quick scan of similar reports on Google finds me an explanation of how to reinstall a single DBD::Oracle, but how do I fix this so that I can test my app with the old version of DBD::Oracle while leaving the current in place?

Edit: more info...

I installed v1.64 of DBD::Oracle from a tar.gz download from CPAN:

#> perl MakeFile.PL PREFIX=/path/to/local/lib #>make && make test

There were test errors. On closer examination, they appeared to just be miscounts of number of tests, so I installed the module:

make install

In looking in the local lib dir, I see that the DBD::Oracle code is there - both DBI.so and DBD/Oracle/Oracle.so

I wrote this test script:

#!/usr/bin/perl BEGIN { use lib '/path/to/local/lib/lib64/perl5'; } use strict; use warnings; use v5.010; use Data::Dumper 'Dumper'; use DBI; say Dumper(\@INC,\%INC); require DBD::Oracle;

(the use/require DBI/DBD are copied from the app I'm debugging. The output I got was:

$VAR1 = [ '/path/to/local/lib/perl5lib/lib64/perl5', '/usr/local/lib64/perl5', '/usr/local/share/perl5', '/usr/lib64/perl5/vendor_perl', '/usr/share/perl5/vendor_perl', '/usr/lib64/perl5', '/usr/share/perl5', '.' ]; $VAR2 = { 'warnings/register.pm' => '/usr/share/perl5/warnings/registe +r.pm', 'XSLoader.pm' => '/usr/lib64/perl5/XSLoader.pm', 'List/Util.pm' => '/usr/lib64/perl5/List/Util.pm', 'warnings.pm' => '/usr/share/perl5/warnings.pm', 'Config_git.pl' => '/usr/lib64/perl5/Config_git.pl', 'DBI.pm' => '/path/to/local/lib/perl5/DBI.pm', 'Config.pm' => '/usr/lib64/perl5/Config.pm', 'Carp.pm' => '/usr/share/perl5/Carp.pm', 'bytes.pm' => '/usr/share/perl5/bytes.pm', 'Scalar/Util.pm' => '/usr/lib64/perl5/Scalar/Util.pm', 'Exporter/Heavy.pm' => '/usr/share/perl5/Exporter/Heavy.pm', 'strict.pm' => '/usr/share/perl5/strict.pm', 'Exporter.pm' => '/usr/share/perl5/Exporter.pm', 'vars.pm' => '/usr/share/perl5/vars.pm', 'constant.pm' => '/usr/share/perl5/constant.pm', 'Config_heavy.pl' => '/usr/lib64/perl5/Config_heavy.pl', 'overload.pm' => '/usr/share/perl5/overload.pm', 'AutoLoader.pm' => '/usr/share/perl5/AutoLoader.pm', 'lib.pm' => '/usr/lib64/perl5/lib.pm', 'DynaLoader.pm' => '/usr/lib64/perl5/DynaLoader.pm', 'Data/Dumper.pm' => '/usr/lib64/perl5/Data/Dumper.pm', 'feature.pm' => '/usr/share/perl5/feature.pm' }; DBD::Oracle object version 1.74 does not match bootstrap parameter 1.6 +4 at /usr/lib64/perl5/DynaLoader.pm line 223. Compilation failed in require at tmp.pl line 14.

So, that use lib statement doesn't appear to be being honored by DynaLoader.

Edit 2:

I tried INSTALL_BASE instead of PREFIX and it appears to have worked! Anyone know a deep reason why that should be? The MakeMaker docs don't appear to clarify.
