Bug 568660 – dev-util/weka: libLINEAR classifier fails with: "liblinear classes not in CLASSPATH!"

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Göktürk Yüksek 2015-12-18 19:00:43 UTC]

weka is failing to run libLINEAR classifier with the error mentioned in the summary. I've installed dev-libs/liblinear but the package does not provide any jar files for weka. I guess something like this is required:
  https://github.com/bwaldvogel/liblinear-weka


Reproducible: Always



Expected Results:  
Watch weka bird dance around happily as it runs the classifier.
