Under Java 11, cannot access jdk.internal.ref.Cleaner #55

Closed bombaywalla closed 5 years ago

Reproduction steps on Mac OS 10.13.6.

First clone the neanderthal repo. Then cd to the hello-world example directory. Then run the following ...

Under Java 9+, you have to explicitly enable base module.

Add this to :jvm-opts in your leiningen project (or the equivalent if you're using something else): "--add-opens=java.base/jdk.internal.ref=ALL-UNNAMED"

Thanks. That worked. Perhaps that should be in the installation docs?

I still have this problem even I use these lines:

  #_=>                w1 (dge 4 2 [0.3 0.6

Looks like you have commented out the line that should not be commented. Remove the #_ just before the double-quote. And see if that helps.

After 2 weeks and whole weekend finally resolved it.

Problem solved:

Try this set cd C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2019\windows\mkl\bin mklvars intel64 where mkl_intel_thread.dll where java set

cd C:\Users\\Documents\GitHub\neanderthal-err\examples\hello-world set LD_LIBRARY_PATH = %PATH% set DYLD_LIBRARY_PATH = %PATH% set

lein repl

(System/getenv "DYLD_LIBRARY_PATH") (System/getenv "LD_LIBRARY_PATH") (System/getenv "PATH")

(require '[uncomplicate.commons.core :refer [with-release]] '[uncomplicate.neanderthal [native :refer [dv dge]] [core :refer [mv!]]]) ;;mtl can be found but needed to use mtlvars.bat in its bin

(with-release [x (dv 0.3 0.9) w1 (dge 4 2 [0.3 0.6 0.1 2.0 0.9 3.7 0.0 1.0] {:layout :row}) h1 (dv 4)] (println (mv! w1 x h1)))

Thanks but it is not me; it is in the example! I now raise a change to that just a moment ago.

I finally found it during my 36 hours struggle to start the GPU-Clojure series. Waste 36 hour of my life. :=)) :-((

The option is under the comment because it is specific under Java 9+ and Java 8 would not recognize it and raise an error. All these things are explained in the Getting started guide.
