Re: [sdljava-users] Problems with JavaSDL.. I've been trying for hours to get this to work.

Hi Chris,

at first I wonder whether this can work:

-Djava.library.path=D:/Programming/eclipse/plugins/org.eclipse.swt.win32_3.1.0/os/win32/x86 
-Djava.library.path="d:/Java Code/sdljava/lib"

You should put both absolute filenames in one argument. On Windows you 
separate usually with a ;
It should look like:

-Djava.library.path=D:/Programming/eclipse/plugins/org.eclipse.swt.win32_3.1.0/os/win32/x86;"d:/Java 
Code/sdljava/lib"

---

Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\Java 
Code\sdljava\
lib\sdljava.dll: Can't find dependent libraries

This one looks like sdljava's JNI library (sdljava.dll) cannot find SDL 
itself. If have no idea how you solve that on Windows elegantly. On 
GNU/Linux and other Unices we install libraries usually system wide 
which is less usually on Windows.
As a workaround you can download SDL's DLLs from libsdl.org and put them 
in the same directory as sdljava.dll.
