[Bug libgcj/20715] New: gcj link error

[jack dot rong at cloakware dot com]

When I tried to compile and link java application into an exacutable using GCJ 
v3.4.3 in Linux Red Hat 3.4.3-9.EL4, it produces error messages:

Looks like one of our jars linked is using the java.awt.* package, which cause 
the problem.

By the way, all our JAVA applications work very well if we don't compile and 
link it into an executable.

Thanks a lot in advance.

You might want to try a snapshot of 4.0.0 which has AWT support builtin.
Also this is not a link error, this is at compile time still.
This error usually shows up if you try to compile a .jar and a .java file at the same time.  This is known 
to be broken, there are a couple of bugs for this.

In 4.0, if you can use indirect dispatch, gcj will use the new
verifier, which is somewhat less buggy.  (Assuming this is a verifier
bug, which is not clear, as there is not enough information here.)

In "4.1" (cvs trunk) the new verifier is always used, even for
"C++ ABI" compilations.

Could you try 4.0 with -findirect-dispatch and see if this still happens?
