Hi Alex, 1.8.0-alpha3 is breaking core.matrix at the moment.
Root cause appears to be related to how protocols are being handled when used with Java arrays: e.g. for the protocol implementation: (extend-protocol mp/PImplementation (Class/forName "[Ljava.lang.Object;") (implementation-key [m] :object-array) (meta-info [m] {:doc "Clojure.core.matrix implementation for Java Object arrays"}) (new-vector [m length] (construct-object-vector (long length))) (new-matrix [m rows columns] (let [columns (long columns) m (object-array rows)] (dotimes [i rows] (aset m i (construct-object-vector columns))) m)) (new-matrix-nd [m shape] (construct-nd shape)) (construct-matrix [m data] (construct-object-array data)) (supports-dimensionality? [m dims] (>= dims 1))) When called as: (clojure.core.matrix.protocols/construct-matrix (object-array 1) [1]) Gives exception: VerifyError (class: clojure/core/matrix$eval10586, method: invokeStatic signature: ()Ljava/lang/Object;) Incompatible object argument for function call java.lang.Class.getDeclaredConstructors0 (:-2) On Thursday, 30 July 2015 06:51:18 UTC+8, Alex Miller wrote: > > Clojure 1.8.0-alpha3 is now available. > > Try it via > - Download: > https://repo1.maven.org/maven2/org/clojure/clojure/1.8.0-alpha3 > - Leiningen: [org.clojure/clojure "1.8.0-alpha3"] > > Tuples have been disabled after further analysis of performance impacts. > > This alpha has initial support for direct linking which you can enable > with -Dclojure.compiler.direct-linking=true > > Direct linking allows functions compiled with direct linking on to make > direct static method calls to most other functions, instead of going > through the var and the Fn object.
