I'm having trouble running some code on a Mac OS X (v 10.6.8) installation. I downloaded and compiled the latest stable version of PARI-GP (2.5.1) - this seemed to be successful. However, PARI doesn't seem to know about some internal functions that it should do. For example, when I try using bnfclassunit, I get
*** at top-level: bnfclassunit(x^2-5)
*** not a function in function call
*** Break loop: type 'break' to go back to GP
bnfinit seems to work fine.
Any suggestions as to what's going wrong here?
This is the list of function names starting "bnf" according to "?6":
bnfcertify bnfcompress bnfdecodemodule bnfinit
bnfisintnorm bnfisnorm bnfisprincipal bnfissunit
bnfisunit bnfnarrow bnfsignunit bnfsunit
Moreover, the word `bnfclassunit` does not appear anywhere in the TeX
source of any of the manuals. So Pari seems not to be at fault.
Are you by any chance confusing functions with member functions?
These are functions of one variable that you call with x.foo instead
of foo(x), and they have their own namespace. You can define you own,
%13 = (z)->real(z)
Some member functions are built-in. See "?.". There's no "classunit",
but there is "fu":
%2 = [Mod(1/2*x + 1/2, x^2 - 5)]
