Greetings all,
I recently (like, 40 minutes ago) installed Perl 5.6.1 on an HPUX 11.0 system.
As my goal is to interact with an Oracle database, I followed Lincoln Baxter's
README.hpux (THANK YOU!) and tried to build a dynamically linked version of
Perl. However, in earlier attempts (stretching back over the last week or so)
it died in the linking stage, admonishing me that a file was created without
position independent code and advising me that I should recompile using the
"+z" flag. As I was using gcc (which has no +z flag) this was very confusing
until I noticed that the file to which the message was referring was libgdbm,
which I had built just last week, and realized that I was using HPUX's ld ('cuz
the GNU binutils ld won't work on HPUX) and this ld doesn't know about gcc.
Well, it was simple enough to fix: go back to the libgdm build and add -fPIC to
the complier options. After that, Perl built and loaded just like the
documentation says it should.
My "bug"? It would have helped me, I think, if the three sets of documentation
were more blatant about building everything PIC. The configure/build process
for libgdbm does not have an obvious method to specify PIC, and neither the
Perl documentation nor Lincoln Baxter's README.hpux remind the user that all
files in a dynamic build need to be PIC. Yes, it's "well known" (and, if I had
been asked, would have said as much...), but a mild reminder might have helped
me.
Also, in the Makefile for libgdbm:
30c30
< CFLAGS = -O -fPIC
---
> CFLAGS = -O
although this is specific to gcc.
As is often the case in the software biz, just a few characters can make all
the difference.
Thank you, and thank you very much for various contributions.
