Xiang Zhang created PYLUCENE-43:
-----------------------------------
Summary: Failed to build PyLucene after the removal of
SetuptoolsVersion in setuptools
Key: PYLUCENE-43
URL: https://issues.apache.org/jira/browse/PYLUCENE-43
Project: PyLucene
Issue Type: Bug
Reporter: Xiang Zhang
*Environment I'm Using*:
* ubuntu 16.04
* cleanly installed python 2.7.15 built with latest pyenv
* Setuptools 40.4.1
* pip 18.0
* pylucene-7.4.0.tar.gz
*Phenomenon*
Step1. build jcc
In JCC's setup.py file, with_modern_setuptools is False by checking if
pkg_resource.SetuptoolsVersions is available.
According to [setuptools
developer|https://github.com/pypa/setuptools/issues/1310], this is not
documented and is already removed, causing jcc not build with shared mode
consequently but no error or warning is prompted.
Step2. build pylucene
The final error comes with the following line:
{code}
python -m jcc --shared --jar
lucene-java-7.4.0/lucene/build/core/lucene-core-7.4.0.jar --jar
....(omitted)..... --version 7.4.0 --module python/collections.py --module
python/ICUNormalizer2Filter.py --module python/ICUFoldingFilter.py --module
python/ICUTransformFilter.py --files 8 --build
....(lots of warning omitted).....

NotImplementedError: JCC was not built with --shared mode support, see JCC's
INSTALL file for more information

make: *** [compile] Error 1
{code}
It was hard to debug given that "JCC is not built with shared mode", actually I
indeed got a _jcc.so library in the build directory.
*Quick Fix for Me*
As long as I believe the setuptools package has enough high version, I force
the with_modern_setuptools switch to be True as the following(at line 210 in
JCC's setup.py):
{code}
...
try:
from pkg_resources import SetuptoolsVersion
with_modern_setuptools = True
except ImportError:
with_modern_setuptools = False
enable_shared = False
with_modern_setuptools = True
if with_modern_setuptools and 'NO_SHARED' not in os.environ:
....
{code}
i.e., the helpers for linux are still useful
then rebuilt JCC, remove the existing one and reinstall, then continue to make
pylucene, all things work now.
