[mkgmap-dev] mkgmap does not compile with Java 8From Paulo Carvalho paulo.r.m.carvalho at gmail.com on Sat Jul 12 14:32:59 BST 2014
Michael, The error message suggests you to compile with the -source 1.7 option. With this option you tell the compiler to treat mkgmap's code with Java 7 specs. You don't need to downgrade your JDK intallation nor wait for mkgmap to upgrade. If you're using an IDE, then you have to check its docs on how to set your project source config to 1.7. cheers, Paulo 2014-07-12 8:00 GMT-03:00 <mkgmap-dev-request at lists.mkgmap.org.uk>: > Send mkgmap-dev mailing list submissions to > mkgmap-dev at lists.mkgmap.org.uk > > To subscribe or unsubscribe via the World Wide Web, visit > http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev > or, via email, send a message with subject or body 'help' to > mkgmap-dev-request at lists.mkgmap.org.uk > > You can reach the person managing the list at > mkgmap-dev-owner at lists.mkgmap.org.uk > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of mkgmap-dev digest..." > > Today's Topics: > > 1. mkgmap does not compile with Java 8 (Michael Prinzinger) > > > ---------- Mensagem encaminhada ---------- > From: Michael Prinzinger <email at mipri.de> > To: mkgmap-dev at lists.mkgmap.org.uk > Cc: > Date: Fri, 11 Jul 2014 15:48:37 +0200 > Subject: [mkgmap-dev] mkgmap does not compile with Java 8 > > Hello, > > I hope this is not a FAQ, but I couldn't find an answer anywhere. > > When I am trying to compile mkgmap with > > java version "1.8.0_05" > Java(TM) SE Runtime Environment (build 1.8.0_05-b13) > Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode) > > running on Windows 7 64 Bit, I get the following errors: > > compile: > [javac] Compiling 480 source files to F:\mkgmap\trunk\build\classes > [javac] warning: [options] bootstrap class path not set in conjunction > with -source 1.7 > [javac] F:\mkgmap\trunk\src\uk\me\parabola\util\MultiHashMap.java:57: > error: name clash: remove(K,V) in MultiHashMap and remove(Object,Object) in > HashMap have the same erasure, yet neither overrides the other > [javac] public V remove(K key, V value ) > [javac] ^ > [javac] where K,V are type-variables: > [javac] K extends Object declared in class MultiHashMap > [javac] V extends Object declared in class MultiHashMap > [javac] F:\mkgmap\trunk\src\uk\me\parabola\util\MultiIdentityHashMap.java:57: > error: name clash: remove(K,V) in MultiIdentityHashMap and > remove(Object,Object) in Map have the same erasure, yet neither overrides > the other > [javac] public V remove(K key, V value ) > [javac] ^ > [javac] where K,V are type-variables: > [javac] K extends Object declared in class MultiIdentityHashMap > [javac] V extends Object declared in class MultiIdentityHashMap > [javac] Note: F:\mkgmap\trunk\src\uk\me\parabola\mkgmap\reader\dem\DEM.java > uses unchecked or unsafe operations. > [javac] Note: Recompile with -Xlint:unchecked for details. > [javac] 2 errors > [javac] 1 warning > > BUILD FAILED > > Is this a known problem?
