New issue 235 by gbeli...@gmail.com: troubles using gmpy with mpmath
http://code.google.com/p/mpmath/issues/detail?id=235




What steps will reproduce the problem?
1. I installed gmplib 5.1.0, mpfr 3.1.1, mpc 1.0.1, GMPY2 2.0.0b3 full
source.
2. configured and make, make install all of these. The tests were OK.
3. I ran my script:

m=2
import os
from mpmath import *
mp.dps=1000
zetazeroval=zetazero(m)


What is the expected output? What do you see instead?
Reported an error

File "zetazero.py", line 12, in <module>
zetazeroval=zetazero(m)
File "/usr/lib/python2.7/site-packages/mpmath/functions/zetazeros.py",
line 394, in zetazero
find_rosser_block_zero(ctx, n)

...
File "/usr/lib/python2.7/site-packages/mpmath/libmp/libelefun.py", line
101, in g
return f.memo_val >> (newprec-prec)
TypeError: unsupported operand type(s) for >>: 'mpfr' and 'int'


The same error was reported at many places when I ran
import mpmath
mpmath.runtests()

File "/usr/lib/python2.7/site-packages/mpmath/libmp/libelefun.py", line
97, in g
return f.memo_val >> (memo_prec-prec)
TypeError: unsupported operand type(s) for >>: 'mpfr' and 'int'

half the tests were passed

What version of the product are you using? On what operating system?
Fedora 16, python 2.7
gmplib 5.1.0, mpfr 3.1.1, mpc 1.0.1, GMPY2 2.0.0b3

mpmath.__version__
'0.17'
mpmath.libmp.BACKEND
'gmpy'


Please provide any additional information below.

Without gmpy calculations went fine

Can you check if this problem persists with gmpy2 2.0.0b4 (or the gmpy
trunk)?

Our administrator tried to install gmpy2 after mpmath, (on CentoOS) and
mpmath stopped working:

it has gmp/5.1.0 and mpfr 3.1.1

Ah, this should already be fixed in the git repository.

Can you check if a source checkout
https://github.com/fredrik-johansson/mpmath works?

After I got the code from git, it seems to have fixed the problem
Thanks!
