Xiangrui Meng commented on SPARK-5669: -------------------------------------- [~srowen] I came across this "GCC Runtime Library Exception" today: https://www.gnu.org/licenses/gcc-exception but I haven't read it closely. It seems that we can include GCC binaries with a NOTICE file. If this is true, the issue becomes less critical. > Spark assembly includes incompatibly licensed libgfortran, libgcc code via > JBLAS > -------------------------------------------------------------------------------- > > Key: SPARK-5669 > URL: https://issues.apache.org/jira/browse/SPARK-5669 > Project: Spark > Issue Type: Bug > Components: Build > Reporter: Sean Owen > Assignee: Sean Owen > Priority: Blocker > Fix For: 1.3.0 > > > Sorry for "Blocker", but it's a license issue.

I'm not clear what it does to running on Windows; > I assume it can still work but the libs would have to be made available > locally and put on the shared library path manually. I don't think there's a > package manager as in Linux that would make it easily available. I'm not able > to test on Windows. > If it doesn't work, the follow-up question is whether that means JBLAS has to > be removed on the double, or treated as a known issue for 1.3.0. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
