To whom it may concern,
I am interested in contributing to documentation, so I am following
http://predictionio.incubator.apache.org/community/contribute-documentation/
on macbook pro, *osx 10.11.6*.
$ cd docs/manual$ gem install bundler$ bundle install$ npm install -g
bower$ bower install
at `bundle install`, it reports
`An error occurred while installing libv8 (3.16.14.13), and Bundler cannot
continue.
Make sure that `gem install libv8 -v '3.16.14.13'` succeeds before bundling.
`
running `gem install libv8 -v '3.16.14.13'`
will give error
../src/objects.h:5252:44: error: shifting a negative signed value is
undefined [-Werror,-Wshift-negative-value]
static const int kElementsKindMask = (-1 << kElementsKindShift) &
~~ ^
../src/objects.h:7386:36: error: shifting a negative signed value is
undefined [-Werror,-Wshift-negative-value]
(~kMaxCachedArrayIndexLength << kArrayIndexHashLengthShift) |
~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^
however, running `gem install libv8` will not give error.
after running `gem install libv8`, `bundle install` still gives error,
insisting I make sure `gem install libv8 -v '3.16.14.13'` works.
Any solution for this problem? Thanks a lot.
Thanks,
Steven
