[GoogleCodeExporter]

What steps will reproduce the problem?
1. Building gmpy2-2.0.0b1 using python2.7 on OSX 10.6.8 with x86_64 architecture
2. Trying to import gmpy2 module in python

What is the expected output? What do you see instead?
I expected the tests to run fine since the module builds without any errors or 
warning messages

What version of the product are you using? On what operating system?
Refer above

Please provide any additional information below.
Below are the sequence of commands run and the outputs and error messages,

I forgot to mention, I am using gmp5.0.5, mpfr 3.1.1 and mpc 1.0.0

I have been looking at mpc 0.9 & mpc 1.0.
mpc 0.9 had a macro RNDC, which has been named MPC_RND in mpc 1.0

Could this be the problem? What can I do to resolve this? I'll keep digging and 
put up an update if I find something.

I think it is fixed in the SVN repository. Can you try that?

I have the same problem. Are you saying the zip package is outdated?

Sorry for spamming. But if I deleted the folder that was extracted by the 
latest zip, and replaced it with SVN checkout, I get this after running the 
setup

Traceback (most recent call last):
  File "test_pack.py", line 2, in <module>
    import gmpy2
ImportError: libmpc.so.3: cannot open shared object file: No such file or 
directory

>> sudo locate libmpc.so
/usr/lib/libmpc.so.2
/usr/lib/libmpc.so.2.0.0

There is no libmpc3, how do you get so.3 ? 

I am on Ubuntu 11.10

/opt/local$ ls
gmp-5.0.5  gmp-5.0.5.tar.xz  gmpy-read-only  include  lib  mpc-1.0.1  
mpc-1.0.1.tar.gz  mpfr-3.1.1  mpfr-3.1.1.tar.gz  share

I've been trying to release a beta2 version but work has gotten in the way. I 
haven't tested with MPC 1.0.1 but I'll do that later tonight. 

You need to tell gmpy2 where the mpc and mpfr libraries are located. Try:

python setup.py build_ext -f -Ddir=/opt/local install -f

Using the latest svn code worked for me. However some of the mpfr tests failed, 
looking at the output it seems the issues are - 
1) o/p text for InvalidOperationError differs on my PC compared to that in the 
test, which should be fine
2) an issue with math functions returning numbers with 15 decimal places, 
compared to gmpy2 functions returning 16 decimal places, I guess this has more 
to do with my python settings
3) lastly - gmpy2.local_context() returns <gmpy2.ContextManagerObject>,  
instead of context(....) as expected by the test ... is this ok?

Thanks for the help!

Several problems all occurred at the same. First, there was a minor change in 
MPC between 0.9 -> 1.0rc1 and the final release of 1.0. That is fixed in SVN 
and will be released as beta2 soon.

Second, the -Ddir option should specify the top-level directory that contains 
GMP, MPFR, and MPC. It should not include a trailing /lib or /include as they 
are automatically added by setup.py.

Lastly, I'm fixing the failures in the test suite. Those failures should be 
fixed in beta2 also.

Thanks for the bug report. Please report any other issues you encounter.

gmpy2 2.0.0b2 has been released and should solve these issues.

Same problem with gmpy2 2.0.0b2, see issue 64
