Mithun Paul commented on PYLUCENE-40:
-------------------------------------

OMG! yes, your patch worked. What would I have done without peer support.

Only difference was that I exported my JCC_JDK from my bash_profile instead of 
passing it as a command line argument. But good lord, 2 weeks it took me to 
reach till this stage of installing JCC. They must definitely have better 
documentation. Alright, see you at the next intersection, the Make file :D

For the record/for progeny: in the patch file, just in case it is not clear, 
what [~rjollos] is doing is, removing lines at the given line numbers and 
adding a few new lines. i.e the lines he removed is shown using the minus sign 
and the ones he added using the plus sign.

> 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_JDK}}, but 
> it's not documented.
> Second, when setting {{JCC_JDK}} is appears to work correctly and use the 
> path to the specified {{JCC_JDK}} 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_JDK}} is set, 
> so it appears that {{JCC_JDK}} is successfully overriding the {{JAVAHOME}}. 
> I'll attach the full output from building on my platform.
