GMPY 1.14 on Mac OS X 10.6 gives 44 test failures about gmpy HOT 9 CLOSED

I'm using python 2.7 btw

Unfortunately, I don't have a Mac so I can't recreate the issue. 

What version of GMP did you use? 

Can you attach the output of the test results?

Does the discussion in this thread provide any clues?

p.s. Are there any specific changes/improvements/additions I can make that will 
help Sympy? I'm working on gmpy2 and I'm willing to make more aggressive 
changes on that version since it isn't stable yet.

Regarding changes that would help SymPy, you should ask Mateusz Paprocki.  He's 
the one who has written most of the code in SymPy that uses gmpy.  

I have GMP5.02 installed, but I'm not sure. Is there a function which tells me 
which version is installed and currently in use ?
I have attached the test results.

Yes, IT was GMP5.02, I deleted libgmp.a and some related files from 
/usr/local/lib/ and reinstalled gmp using macports. It installed GMP%.01. 
Still, 44 test failures.

This is just a guess, but I think there may be a 32 vs. 64-bit version 
mismatch. I'm not sure how to verify that on a Mac. To compile GMP, you may 
need to use eithe -m32 or -m64 so that it matches Python. For performance 
reasons, I recommend 64-bit versions of both. 

Could you tell me what is the best way to install GMP ?
I would also need to uninstall GMP first.

You may want to read some of the comments on issue 11. That issue dealt with 
gmpy2 but the issue is probable the same. By default, python runs as a 32-bit 
application on OSX but GMP compiles as a 64-bit library. To compile GMP as a 
32-bit library, you need to pass ABI=32 to configure (not -m32 as I said 
earlier). Or you can let GMP install as a 64-bit library, and force python to 
run as a 64-bit application. The following command is from issue 11.

$# defaults write com.apple.versioner.python Prefer-32-Bit -bool no

Note: the -Ddir=<path> option is not available in gmpy 1.14. If setup.py can't 
find GMP automatically, use the following:

python setup.py -build_ext -I<path>/include -L<path>/lib -R<path>/lib

See issue 11 for build instructions for OSX. Let me know if that doesn't work 
for you.
