Hi,
John or someone else can perhaps convey this to the Pari developers. Would
it be possible for them to add the -fPIC option on at least all Solaris
systems. (Both SPARC and x86). If code goes into a shared library, it
should be compiled position independent. It is unreliable if this is not
done. There's some relevant information about this here.
http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Code-Gen-Options.html#Code-
Gen-Options
http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/Link-Options.html#Link-Options
I believe it would be more reliable to build with -fPIC when the code is
going into a shared library - irrespective of the platform. What one
should ensure though is there is not a mixture of PIC and non-PIC code, as
that can be unreliable too.
I've not had a chance to look at the other issues, but as far as I can
see, this update completely breaks a 64-bit build on Solaris or
!OpenSolaris.
I've also noticed that Pari reports that ''readline'' is not working on
Solaris systems. Yet the ''readline'' is definitely working in my Sage
builds on Solaris. Several parts of Sage link against readline (Pari, gap,
Singular, ECL, Python ...). None of them believe that ''readline'' is
broken, but Pari does.
