hi

i installed gcj (compile java file, when to try it)
when i try to compile a little HelloWord i get:

collinm@linux:~> gcj --main=HelloWord -o HelloWord HelloWord.java
/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../../../i586-suse-linux/bin/ld: can't find -lz

any idea?

Try creating a symlink libz.so to libz.so.1 in the same directory as it, then run ldconfig. All as root, of course.

I've tried using the swing package with gcj but with no luck, also a simple hello world program using JOptionPane. Good to hear it works with javac though, keen to give it a try.

I had the same problem as your previous question, seems everything went awry when I deleted suse 8.2 and went to 9.1. Going to try the symbolic link thing when I get home. Thanks!!
