Ryan J Ollos commented on PYLUCENE-40:
--------------------------------------
Thanks for the continue help despite my ignorance on Java technology. I have
Java 9 installed, but I want to build with {{jdk1.8.0_141.jdk}}:
{code:java}
$ls /Library/Java/JavaVirtualMachines/
jdk-9.0.4.jdk jdk1.8.0_141.jdk jdk1.8.0_91.jdk
jdk1.7.0_80.jdk jdk1.8.0_25.jdk
{code}
I looked at all the variables you listed, and only {{JCC_JAVAC}} and
{{JCC_JAVADOC}} appear to be dependent on the JDK path. If we use the full path
to the executables, derived from {{JCC_JDK}}, then the library appears to build
correctly.

To build I use:
{code}
$ JCC_JDK=`/usr/libexec/java_home -v 1.8` python setup.py
{code}
I've attached build output in [^jcc_build_output2.txt].
Side note: The patch probably needs to be modified using a python 2 and 3
compatible {{print}}. I'm currently using Python2.7. Also, it would be good to
print to stderr, like is done for the "found" statements in {{helpers2}} and
{{helpers3}}. Maybe we could add a {{printerr}} function in each helpers module?
I will need to familiarize myself with the library in order to do testing and
ensure everything is working.

> 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.
