Description W. Michael Petullo 2004-07-09 15:14:32 UTC

Description of problem:
I would like to see gcc-java built to support AWT.  A GTK AWT peer may
be built by giving gcc's configure script the --enable-java-awt=gtk
argument.  Though its implementation is not complete, it would be nice
to be able to start testing gcc's GTK AWT peer using a Fedora-provided
package.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
Try to execute a java application that uses AWT and was compiled using
Fedora's gcc-java package.

Comment 1 W. Michael Petullo 2004-08-22 02:39:15 UTC 
I looks like the GTK AWT peer is built as of gcc 3.4.1-8.  However, on
PowerPC things don't seem to work quite right.

"gcj --main=HelloWorldAWT HelloWorldAWT.java" compiles fine.

"LD_PRELOAD=/usr/lib/gcc/ppc64-redhat-linux/3.4.1/lib-gnu-java-awt-peer-gtk.so
./a.out" executes fine.

But "./a.out" says:

Exception in thread "main" java.awt.AWTError: Cannot load AWT toolkit:
gnu.java.awt.peer.gtk.GtkToolkit
   at java.awt.Toolkit.getDefaultToolkit() (/usr/lib/libgcj.so.5.0.0)
[...]

Why would the explicit LD_PRELOAD be needed?
Comment 2 W. Michael Petullo 2004-09-04 17:58:55 UTC 
This seems to be fixed in gcc-java-3.4.1-10.  LD_PRELOAD is no longer
needed.
