| At some point (probably in 3.2) the support for shared modules built using Modules/Setup was broken, for two reasons: - Python no longer considers 'foomodule.so' when looking for a module called 'foo', but Modules/makesetup still appends 'module.so' for a 'foo' module. - Python no longer considers Modules/ to be the exec_prefix (and instead uses what was loaded from the build-info .txt written by setup.py) but the build process still leaves these Modules/Setup-built shared modules in the Modules directory (and it doesn't know about the directory setup.py will make, so it can't really do anything else.) This patch fixes both problems, by making Modules/makesetup name shared library modules 'foo.so' and by adding the Modules subdirectory to sys.path (after the setup.py-provided directory) when running from the build directory. (The existing build process has no problem _installing_ the Modules/Setup-built extension modules, it's just Python that doesn't know how to find them.) |

| Your original patch LGTM. However, since it was written, Setup *shared* support became even more broken due to changes in Makefile macros. Attached is an updated patch. I've never tried customizing Setup before so I don't have a lot of confidence that it now works as expected in all cases, but I tried a few cases (like building _ssl with a non-standard OpenSSL on OS X) and they did work. |

| I reopen the issue because these changes broke the decimal module when the _decimal module is missing: see the issue #22285. Martin von Loewis proposed to build modules in the build directory, not in the Modules directory directly: http://bugs.python.org/issue22285#msg225961 |

| Clearly this breaks running from the build directory for various modules when their optional C extension module build fails. I'll either change the Setup shared builds to use a build directory or revert the path changes prior to the upcoming 3.4.2. |

| Stéphane, as I understand it, this issue covers two problems: (1) Building and installing shared modules using Modules/Setup was broken for current Python 3 releases; (2) Using those shared modules when running Python from a build directory (rather than from a normal installed Python) is broken. Problem (1) is now fixed. Problem (2) remains to be properly fixed; it's a little tedious to get right as a fix needs to take into account the SO_ABI and ensure built modules get properly cleaned and all the right Makefile dependencies work. I'd be happy to review a patch if someone gets to it before I do. But it seems to me that (1) was the serious problem; (2) is more of a minor annoyance for developers with easy workarounds, e.g. use PYTHONPATH or install Python to a temporary location for testing. |

| Hi Ned, For the first point, maybe close this issue and open a new bug for the second. What do you think? |

| Sorry, I don't see the point of opening another issue, especially since most of the discussion in this issue has been about the second problem. I have updated the issue title to be more specific, though. |
