numexpr-2.1 does not build with Python 3.2 (builds fine with Python 2.7) #100

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I am trying to compile numexpr-2.1 on my Gentoo system, but have been unable to 
build numexpr against Python 3.2. I confirmed that this problem occurs whether 
I build numexpr within Gentoo's Portage package manager, or whether I download 
the source and run "python3.2 setup.py build" manually. In either event, the 
build looks something like this:

The problem seems to arise at the following line:

Warning: Assuming default configuration (numexpr/tests/{setup_tests,setup}.py 
was not found)Traceback (most recent call last):

I note that neither of the requested files exists, although there is a file 
named numexpr/tests/test_numexpr.py. Also, the package compiles without 
complaint using python2.7. Is it possible that Python 3.2 requires a different 
format of test file, one which is not found in this package? Would renaming the 
existing test file be a sufficient solution, or is further work necessary?

I should probably also include the build log from the successful build using 
Python 2.7:

It appears the very first line of this version references the same two missing 
files as the Python 3.2 version, so that's not the key difference...perhaps 
someone with closer knowledge of this package can help.

Antonio, could you take a look at this?

Any progress on this bug? It's been over a month...I could provide additional 
info about my system (which still experiences this bug) if that would help.
