Hi Joe, Try this as a workaround: Set the LD_LIBRARY_PATH environment variable to $INSTALLED_LOCATION_OF_SWIFT/usr/lib/swift/linux
This should only affect the REPL and not compiled code. I think this is supposed to be fixed in the top of tree Swift but not in the Dec 1 binary drop. - Tony > On Dec 11, 2015, at 5:54 AM, Joseph Bell via swift-corelibs-dev > <swift-corelibs-dev@swift.org> wrote: > > All, > > Howdy.
