[jira] [Commented] (PYLUCENE-40) Document use of JCC_JDK

["Andi Vajda (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PYLUCENE-40?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16361752#comment-16361752 ] 

Andi Vajda commented on PYLUCENE-40:
------------------------------------

I assume you mean JCC_JDK and not JCC_JRE ? (there is no JCC_JRE in setup.py).

And this bug is all about not trying to find the JDK (and print what got found) when JCC_JDK is set ?

> I found two issues when trying to [help someone on Stack Overflow|https://stackoverflow.com/questions/48711714/] build the library. First, the [documentation on PyPI|https://pypi.python.org/pypi/JCC/] states:
> {quote}JCC’s setup.py file needs to be edited before building JCC to specify the location of the Java Runtime Environment’s header files and libraries.
> {quote}
> However, it appears you have a better mechanism of setting {{JCC_JRE}}, but it's not documented.
> Second, when setting {{JCC_JRE}} is appears to work correctly and use the path to the specified {{JCC_JRE}} in the compilation, but the first line of output might indicate that a different JRE is being used:
> {code:java}
> $JCC_JDK=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home python setup.py install
> found JAVAHOME = /Library/Java/JavaVirtualMachines/jdk1.8.0_141.jdk/Contents/Home
> found JAVAFRAMEWORKS = /System/Library/Frameworks/JavaVM.framework
> ...
> {code}
> So maybe the found {{JAVAHOME}} should not be printed if {{JCC_JRE}} is set, so it appears that {{JCC_JRE}} is successfully overriding the {{JAVAHOME}}. I'll attach the full output from building on my platform.
