Re: Trouble with java on arm?

It appears there is. A couple years ago vtk was failing to build on arm due memory issues: java.lang.OutOfMemoryError: Java heap space see https://bugzilla.redhat.com/show_bug.cgi?id=1115920 To get around that we started specifying 2GB of heap space via: JAVA_TOOL_OPTIONS=-Xmx2048m Now with the updated java on aarch32 I'm getting: Error executing java -version: 1 Picked up JAVA_TOOL_OPTIONS: -Xmx2048m Error occurred during initialization of VM Could not reserve enough space for 2097152KB object heap Are the armv7hl builders really that strapped for RAM, or is this a java bug in the new build? I'm trying a scratch build without this option to see if it works that way.

ivy builds in EPEL7
by Christopher 23 Dec '16

23 Dec '16

It's a shame that ivy-local isn't available in EPEL7. Is this because it's part of javapackages-tools and RH has an older version packaged in RHEL7, so javapackages-tools cannot be updated? If that's the case, it might be helpful if the ivy-local stuffs could be shipped separately for EPEL7. Related: Does anybody have a good example ant/ivy package building in EPEL7 I can peek at? I'm trying to get zookeeper packaged in EPEL7, but I really don't know how to make things work without ivy-local. I'm a maven person, and ivy is a so completely foreign to me, I'm not sure where to start. I know it's possible to resolve locally, but I'm just not sure how to make it work, and I learn best by example. Any help is appreciated. -- Christopher
