Re: bnfinit: the PARI stack overflows

Thank you very much for Your reply.

2) I will try to download v 2.5.0, read your install documentation and try to compile it myself.
I was advised to use fink, but as far as I understand, it only results in a old version.  Should
I try to uninstall the old version first?

1) gp -f and bnfinit(x^2 + 1 ) produce:

bash-3.2$ gp -f
                  GP/PARI CALCULATOR Version 2.3.5 (released)
          i386 running darwin (x86-64/GMP-5.0.2 kernel) 64-bit version
compiled: Oct 13 2011, gcc-3.0 (tags/Apple/clang-211.10.1) (based on LLVM 3.0svn)
                (readline v5.0 enabled, extended help available)

Type ? for help, \q to quit.
Type ?12 for how to get moral (and possibly technical) support.

parisize = 8000000, primelimit = 500000
? bnfinit(x^2 + 1)
  *** bnfinit: the PARI stack overflows !
  current stack size: 8000000 (7.629 Mbytes)
  [hint] you can increase GP stack with allocatemem()

? 

END OF OUTPUT.

Increasing the stack size produce the same output.

1) We would need more details: type gp -f in a terminal, then

 bnfinit(x^2+1)

What happens ?

2) 2.3.5 is a very old version, why not upgrade to version 2.5.0 ? See
[ I have no idea whether this is available under Fink, but you can
always download it from http://pari.math.u-bordeaux1.fr/download.html
then compile it yourself ]

Cheers,
