Question

I just wanted to test JAVACPP and tried the first example from the webpage within my eclipse:

http://code.google.com/p/javacpp/
(LegacyClass and LegacyLibrary)

As soon as I type:

javac -cp libs\javacpp.jar:. src\LegacyLibrary.java

into the commandline I get the following error message:

src\LegacyLibrary.java:1: error: package com.googlecode.javacpp does
not exist import com.googlecode.javacpp.*;

src\LegacyLibrary.java:2: error: package
com.googlecode.javacpp.annotation does not exist import
com.googlecode.javacpp.annotation.*;

src\LegacyLibrary.java:4: error: cannot find symbol
@Platform(include=”LegacyLibrary.h”)

symbol: class Platform src\LegacyLibrary.java:5: error: cannot find
symbol @Namespace(“LegacyLibrary”)

symbol: class Namespace src\LegacyLibrary.java:7: error: cannot find
symbol
public static class LegacyClass extends Pointer {
symbol: class Pointer location: class LegacyLibrary src\LegacyLibrary.java:13: error: cannot find symbol
public native @ByRef String get_property(); public native void
set_property(String property);
symbol: class ByRef location: class LegacyClass src\LegacyLibrary.java:16: error: cannot find symbol
public native @ByRef String property(); public native void property(String property);
symbol: class ByRef location: class LegacyClass src\LegacyLibrary.java:8: error: cannot find symbol
static { Loader.load(); }

symbol: variable Loader location: class LegacyClass 8 errors

Why do I get it?

Is it possible to use JavaCPP not having *.cpp and *.h file, but just having a *.dll file?
Or what exactly do I need for using this library?

You’re using Windows. Replace the colon ‘:’ by a semi-colon ‘;’.
