Hi,
My problem is, how to transform a polynomial, say f(x)=x^2+1 into the
corresponding equation f(x)==0?
For example, I start with
R = PolynomialRing(ZZ,x)
f = R.random_element(degree = 3)
Then
f == 0
returns false. And that's a good thing, of course. But now I want to
solve f == 0 mod 7,

Hello, everyone,
I would like to create a real number from its continued fraction
expansion. I know it is possible to call ``CFF([0,1,1,1,1,1,1]).value()

pass an iterator as an argument to the function ``CFF(...)`` so that I

I don't know. Would be nice, though.
i.e. is there something that can
do this?

So on t2 there is no /usr/local/lib/sparcv9, so that's a bit useless!
Does this mean t2 is not capable of running 64 bit binaries?

On t2 all the tests fail, complaining of the same issue. If I actually
go into the tests directory and run one of the test scripts directly,
here is what it does:
./t-modlinv
ld.so.1: t-modlinv: fatal: libmpir.so.8: open failed: No such file or directory
Killed
So let's see what the script does:
I forgot to mention, the long deprecated function mpz_random has also
finally been removed.

So it can't find libmpir.so.8. But I don't see why.

Total random guess: could it be that you need this to be in your
DYLD_LIBRARY_PATH, too?

OK, on gcc54 only the C++ tests fail. But they always did. There is
actually a library missing from the machine which is needed to run
binaries compiled by the C++ compiler. All the C test binaries pass on
gcc54.
So the only issue is actually on t2. Basically I think there is a

No, since gcc is not installed under /usr/local, there is no

One sensible solution would seem to be to set
