---------------------------------------
Summary: Linking libjvm seems to prevent PyPi upload
Key: PYLUCENE-69
URL: https://issues.apache.org/jira/browse/PYLUCENE-69
Project: PyLucene
Issue Type: Question
Reporter: Clément Jonglez
As mentioned in
[https://issues.apache.org/jira/projects/PYLUCENE/issues/PYLUCENE-68] , I am
trying to package the Orekit Python wrapper from [~petrush] (which uses JCC) to
PyPi.
I used the --wheel option to compile a wheel and not an egg, and I tried to
upload the wheel to PyPi.
But PyPi refuses my wheel with the answer :
{noformat}
Binary wheel 'orekit-11.3.3-cp312-cp312-linux_x86_64.whl' has an unsupported
platform tag 'linux_x86_64'. {noformat}
After reading about why this error occurs (
[https://peps.python.org/pep-0513/#rationale] ) , I tried to convert the wheel
to a manylinux wheel by using:
{code:java}
auditwheel repair dist/orekit-11.3.3-cp312-cp312-linux_x86_64.whl{code}
Which returned the following error:
{noformat}
auditwheel: error: cannot repair
"dist/orekit-11.3.3-cp312-cp312-linux_x86_64.whl" to "manylinux_2_5_x86_64" ABI
because of the presence of too-recent versioned symbols. You'll need to compile
the wheel on an older toolchain.{noformat}
I then ran the following command to get more information about which symbols
are problematic in the wheel:
{code:java}
auditwheel-symbols --manylinux 2_34
dist/orekit-11.3.3-cp312-cp312-linux_x86_64.whl{code}
Which returned:
{noformat}
orekit/_orekit.cpython-312-x86_64-linux-gnu.so is not manylinux_2_34 compliant
because it links the following forbidden libraries:
libjvm.so{noformat}
I tried removing -ljvm from the LFLAGS list in jcc's config.py, but as expected
the Python program then fails on starting the JVM:
{noformat}
Traceback (most recent call last):

undefined symbol: JNI_GetDefaultJavaVMInitArgs{noformat}
I don't have any more clues... Alternatively, I could try to package the Orekit
Python wrapper as a source distribution (using
[https://issues.apache.org/jira/projects/PYLUCENE/issues/PYLUCENE-27] and
[https://issues.apache.org/jira/projects/PYLUCENE/issues/PYLUCENE-68] ), but
this would mean that a user would need to wait approx. 10 minutes for the wheel
to compile when running pip install...
