Fwd: GCJ version 4.3.3 (gcc --enable-languages) error : The import acm cannot be resolved

[Malik Benkirane]

Hello,

Here is the program i wish compile with gcj :

>
> import acm.graphics.*;
>
> import acm.program.GraphicsProgram;
>
> public class myfirstgraphics extends GraphicsProgram  {
>
> public void run() {
>
>        add(new GLabel("hello, world", 100, 100));
>
>        }
>
> }

Here is the files in the directory from where i'm running gcj :

> acm.jar  myfirstgraphics.java

But even if I specify CLASSPATH ... i always get same errors :
$> CLASSPATH=. gcj --main=myfirstgraphics -o test myfirstgraphics.java

I really need your help for resolving this problem because JVM is too
slow on my machine. Thank you !

You have to include jarfiles in the classpath.  This is true, AFAIK, for
every java compiler.

 CLASSPATH=.:acm.jar gcj --main=myfirstgraphics -o test myfirstgraphics.java --main=myfirstgraphics
