[jnc-users] exe won't run on one of my computers

[paul s. <pgs...@ya...>]

I compiled a program on the machine where I installed JNC and it worked fine. I 
then copied the the exe file to another computer and it gave the following 
output when it ran:
Exception in thread "main" java.lang.unsatisfiedlinkerror: util  can't open the 
module 

at
java.runtime._load(con4sc3.exe).....
Both computers are running vista and the program uses some graphics from awt.
When I do the same test with "helloworld" it runs on both computers.
Please can anyone help with the problem?
Paul.

Did you read the compilation messages? See below...

Sounds like you didn't copy the "lib" directory that was put in the same 
location as the compiled binary. There is a message at compilation time 
explaining that you need that directory.

Because it doesn't need any additional dlls at runtime.


Hope that helps

There was no message. Here's the compiler output:

Yes. I copied the lib directory and it works. Thanks.
I have to start the application twice from the console to get it to display. The 
first time the application runs and finishes without displaying the graphics - 
that is it goes back to the command prompt on the console. The second time it 
works correctly. It's the same on both machines (running vista).

Well, delete the lib directory and press compile again ;-)
The message is only shown at the first compilation when the additional 
files are being copied. At least as far as I remember... It's quite a 
while ago I programmed that.

There's a thread race in GCJ. AWT is almost always running into it. SWT 
is working much better...
