I don't know what more I can do. First, your gcj is broken, now even
your shell is broken. Are you sure that your computer works at all?
Andrew.
My computer works perfectly and I have no problem with my shell. I can compile c++ code with g++ but the problem comes from gcj...
thank you for your help. I will compile my java file with javac it is much better than gcj
for the ls and the unzip -l Hello.jar, it generate an empty hello.jar
[charfi@is010178 hello_JAVA]$ ls
Hello.jar Hello.java Hellomain.i Hellomain.s Hello.o Hello.s Hello.zip
[charfi@is010178 hello_JAVA]$ unzip -l Hello.jar
Archive: Hello.jar
warning [Hello.jar]: zipfile is empty
thank you again.
