Following 846325, I am attempting to install DBI and DBD::Oracle under a newer version of Perl. DBI was successful. For DBD::Oracle, I:

1. Exported my $ORACLE_HOME and added $ORACLE_HOME/lib to $LD_LIBRARY_PATH.
2. Added use lib '/home/hbm/perllib/DBI' to Makefile.PL.
3. Ran perl Makefile.PL LIB=/home/hbm/perllib -m $ORACLE_HOME/rdbms/demo/demo_rdbms.mk, and got "kit… looks good".
4. Ran make and got:

5. I commented out -fno-strict-aliasing from Makefile, but that didn’t get me further.

Node 765053 was promising, but my line of Oracle.h looks fine (I think?):

sword  OCIXMLTypeCreateFromSrc( OCISvcCtx *svchp, OCIError *errhp,
                     OCIDuration dur, ub1 src_type, dvoid *src_ptr,
                     sb4 ind, OCIXMLType **retInstance );

Any advice? Thanks.

Update:

Thank you almut and mje! I didn't confirm your theories individually, but I believe you were both correct. I started over with DBD::Oracle v1.17 and put a newer version of gcc in my PATH. Those changes got me past make.

6. Then make test failed, unable to find DBI.
7. I added use lib qw(/home/hbm/perllib/DBI) to t/*.
8. That improved things, but one test failed, "ld.so.1: perl: fatal: libmm.so.12".
9. Per 598996, I ran ldd -s blib/arch/auto/DBD/Oracle/Oracle.so. (Thanks again, almut!)
10. I located libmm.so.12 and added its path to LD_LIBRARY_PATH.
11. Almost there, I exported ORACLE_USERID="myuser/pass" and ORACLE_SID="mysid".
12. All tests passed; it installed; and no more segmentation fault!
