[Java-readline-users] java readline on windows

[Craig M. <cr...@eb...>]

Hi,

I'm trying to get libreadline-java-0.8.0 working on windows XP (pro) 
under cygwin. Unfortunately the JVM refuses to load JavaGetline.dll no 
matter where I install it. I've tried putting it in  the current working 
directory, c:/WINDOWS and c:/WINDOWS/system32. Although the JVM can see 
it in all locations it fails to load it with the same error message 
"java.lang.UnsatisfiedLinkError: ... JavaGetline.dll: Invalid access to 
memory location."

Example error message generated by ReadlineTest program:

[craig@acer:src]$ java -classpath ../libreadline-java.jar 
test.ReadlineTest dummy Getline
java.lang.UnsatisfiedLinkError: C:\WINDOWS\JavaGetline.dll: Invalid 
access to memory location
        at java.lang.ClassLoader$NativeLibrary.load(Native Method)
        at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1560)
        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1485)
        at java.lang.Runtime.loadLibrary0(Runtime.java:788)
        at java.lang.System.loadLibrary(System.java:834)
        at org.gnu.readline.Readline.load(Readline.java:133)
        at test.ReadlineTest.main(ReadlineTest.java:60)


JVM :

[craig@acer:classes]$ which java
/cygdrive/c/j2sdk1.4.2/bin/java


Any idea how to make the jvm load the dll? Do I need an XP version, or a 
version compiled to work with the 1.4.2 JVM? If so, is it possible to 
compile the dll with cygwin's gcc rather than Visual C++ (I read 
something about this topic in the mailing lists but wasn't sure what the 
answer was)?

Craig.

Hi Craig,

the JavaGetline.dll in the contrib-directory is only created with cygwin, it 
should run without it. Can you reproduce your problem from a "normal" 
DOS-prompt (to be honest: I have not yet worked with XP, so I don't know if 
it still has a DOS-prompt).

It might be possible that the DLL does not run under XP (the Visual C++ 
compiler is rather old). I have not yet managed to create a working DLL with 
cygwin, it should be possible but I can't figure out how.

I get the same result when  I run it from a DOS prompt. Looks like we'll 
need a new dll for XP.
