Re: Compiled C modules are not found by test suite (Was: Help needed for python-biopython which splits up modules into two packages per Python version)

  Hello,

  I got the code and the debian directory.  I confirmed that extension 
modules are in the build directory, not alongside the Python modules, so 
they can’t be imported from tests.

  There are two ways to fix that: either make distutils build the 
extensions alongside the Python modules, or make the test import all 
code from the build directory.  I’m surprised that this isn’t a common 
issue for PMPT.

  I tried the first solution and did not see a difference in tests: 
both times, 223 tests were run successfully.  I’d like to reproduce the 
errors you mention to be sure that any change I make is actually a fix.

  Unfortunately, there is a long-standing bug in distutils where 
extensions modules built alongside the Python modules are not found by 
the install command.  This means that you’d have to compile twice (once 
in-place to run the tests, one to a build directory to install to 
debian/tmp/etc.), or that you’d prefer the other fix.

  Cheers
