How I built DBD::Oracle under HPUX ...

Just (march 17, 2000) managed to build DBD::Oracle under HPUX 11.0. If you are trying to do the same and have found that it's not a piece of cake, you may read on.

Here is my configuration:

• Oracle 8.1.6
• HP's commercial C-Compiler. Not gcc and not the bundled one
• HPUX 11.0, 32 Bit
• Latest version of perl, DBI and DBD

Rebuilding perl

Yes, I had to rebuild my perl (a guy from HP support gave me that tip):

• Added the linker switch "+s", to make the dynamic loader search through the directories in $SHLIB_PATH. Maybe this is not necessary, but it helps when you use the same perl executable on different machines with different directory structures. In this case you just have to make SHLIB_PATH point into $ORACL_HOME/lib and the dynamic loader will be able to find the libraries.
• Linked with the libraries "-lcl -lpthread". I first tried without those libraries, but then I got lots of errors during tests of DBD::Oracle from the hpux dynamic loader dld.sl. After linking you may check your perl executable with chatr: "chatr ./perl" the libraries libcl.sl and libpthread.sl should appear in the output.

Afterwards I build DBI without any special settings. DBD::Oracle requires again some modifications:

• Added the libraries "-lclntsh -lqsmashr"
