Thread: --enable-perl doesn't like Solaris

Justin Clift (jclift@iprimus.com.au) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
--enable-perl doesn't like Solaris

Long Description
When testing which 7.1RC1 options are working on Solaris 8 SPARC, I've come across this when using --enable-perl.

It appears that the ./configure script is defining -KPIC somewhere in the perl interface stuff, and this is causing the
"make"to bomb out.  I'm pretty sure from memory that -KPIC is not something that gcc on Solaris likes, and will need to
be-fPIC -shared or something else. 

Please note, on this system 'cc' is a soft link to gcc, for those times I forget to set CC (like this time).

Sample Code
./configure --p=/opt/postgresql71 --enable-syslog --with-openssl=/opt/openssl --with-python --with-perl

The Perl build environment is not provided by us, it comes from the
ExtUtils::MakeMaker module.  MakeMaker is misdesigned in that it assumes
that the user will use the same compiler for building his modules as the
one he used for building perl itself.  So if you got Perl from Sun, then
it's likely to have been compiled by Sun's cc.

Solution 1 is to hack MakeMaker and/or the Makefile it generates to fix
the options.  (Replacing -KPIC by -fPIC might do.)

Solution 2 is to recompile Perl with gcc.  This would also give you a
chance to build a shared libperl, so you can use PL/Perl.
