[jira] [Commented] (KUDU-2465) Kudu kudu-python package fails on import

["Todd Lipcon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KUDU-2465?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16505532#comment-16505532 ] 

Todd Lipcon commented on KUDU-2465:
-----------------------------------

The issue seems to be that you're using a Debian 8 deb on Debian 9. I believe Debian 9 switched to using the c++11 ABI by default, whereas Debian 8 used the old ABI. So, your compiled Python library isn't able to resolve the symbols from the deb you've installed.

It may be possible to influence the ABI when compiling the python library by somehow injecting -D_GLIBCXX_USE_CXX11_ABI=0 into the cxxflags, but I'm not sure about how to do that through pip.
