Comment:
This has now been resolved, thanks to Marc Glisse's help after I posted
the query to comp.unix.solaris. The PARI code was missing the gcc compiler
flag -fPIC. Why PARI built on my own Blade 2000 but not on the 16-core
T5240 (t2.math.washington.edu) is not clear to me.
Here's a patch, which adds -fPIC to one of the files used to generate the
Makefile that PARI uses.
http://sage.math.washington.edu/home/kirkby/Solaris-fixes/pari/
Basically all my patch does is to add this to the top of spkg-install,
which adds -fPIC
{{{
# As of PARI 2.3.3, the compiler flag -fPIC is not added on Solaris, but
it needs to be. It basically adds:
if [ `uname` = "SunOS" ]; then
sed 's/-fomit-frame-pointer/-fomit-frame-pointer -fPIC/g'
src/config/get_cc > src/config/get_cc.$$
mv src/config/get_cc.$$ src/config/get_cc
fi
}}}
and remove that below
{{{
# PARI doesn't set PIC correctly on Solaris, so we do this.
if [ `uname` = "SunOS" ]; then
CFLAGS=$CFLAGS" -fPIC"
export CFLAGS
fi
}}}
since the latter code was not working, despite it's obvious attempts to
add -fPIC
