System: Linux churchill 2.4.3-12 #1 Fri Jun 8 15:05:56 EDT 2001 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ./configure --prefix=/home/user/jmr/app/gcc
>Description:
If there is an interface I with one method f(), and AX is an
abstract class implementing I, and AY is marked as extending AX
(but not marked as implementing I), and AY contains a method
g() that calls f(), the AY.java will not compile.
>How-To-Repeat:
Create the files:
I.java:
public interface I {
void f();
}
AX.java:
abstract class AX implements I { }
AY.java:
abstract class AY extends AX /*implements I*/ {
void g() {
f();
}
}
Then gcj -v AY.java fails as follows:
Reading specs from /home/user/jmr/app/gcc/lib/gcc-lib/i686-pc-linux-gnu/3.2/specs
Reading specs from /home/user/jmr/app/gcc/lib/gcc-lib/i686-pc-linux-gnu/3.2/../../../libgcj.spec
rename spec lib to liborig

AY.java: In class `AY':
AY.java: In method `AY.g()':
AY.java:3: error: No method named `f' in scope.
f();
^
1 error
It works if AY is also marked as implementing I, so this is a
workaround.
This code compiles with javac.

Hello,
this behavior still exists with gcc 3.2, 3.3 branch and mainline
(20030511).
