Re: gcj: error trying to exec 'ecj1': execvp

[David Michel <dmichel76 at googlemail dot com>]

Thanks it compiles fine now, but now I get an Exception at runtime:

Exception in thread "main" java.awt.AWTError: Cannot load AWT toolkit:
   at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:607)
   at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment.java:103)
   at java.awt.Window.<init>(Window.java:133)

Caused by: java.lang.ClassNotFoundException:
   at java.lang.Class.forName(natClass.cc:101)
   at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:583)
   ...7 more

I simply run this for all the java source code to produce the object files:
/local/gcc-4_4-branch/install/bin/gcj -O0 -g0 -c "--classpath=./:"
foo.java -o foo.o

and then, link them together with:
/local/gcc-4_4-branch/install/bin/gcj -O0 -g0 --main=GUI foo1.o
foo2.o..... -o ./a.out

Obviously, it seems that it cannot find AWT, but I don't know why and
how to solve this.

Many Thanks in advance for your help

David
