'java.lang.String' has no method

'java.lang.String' has no method

 From what I understand based on gcj e-mail and bug archives, I should 
not be seeing this error in 4.4.0,
so what am I doing wrong?

It's very hard to say.  Have a look in libgcj.jar:

 jcf-dump -classpath /home/aph/gcc/gcc-4_4-branch/install/share/java/libgcj-4.4.1.jar java.lang.String

You should see:

Method name:"format" public static varargs Descriptor: (java.lang.String,java.lang.Object[])java.lang.String

Make sure you're using the same libgcj.jar as the compiler.

Re: 'java.lang.String' has no method

[Keith]

Thanks. That was it.I was using libgcj-4.3.0.jar rather than 
libgcj-4.4.0.jar

Does libgcj-4.4.0.jar support Java 1.6? If so there are some 1.6 methods 
missing for java.util.ResourceBundle and java.net.NetworkInterface. If 
not, then never mind.
Eventually, I will try and suggest some patches for the the missing 
methods, but right now
I have code to get out so I am doing 1.5 work-a-rounds.

Thanks,

Keith

It supports bits of it:

http://builder.classpath.org/japi/openjdk6-libgcj.html

And yes, there are known holes in java.net and ResourceBundle.  I've
looked at implementing them a couple of times, but not yet got round
to it.

Knowing which methods should be prioritised for implementation (i.e.
because people actually use them in real-world code) would be very
useful.  And patches even more so!

com/performanceplanningsystem/ui/PPS.class is compiled into 
com_performanceplanningsystem_ui_PPS.o
and archived in lib/libPPS.lib

The compile flags for PPS.class are  -O0 -m32 -fjni -findirect-dispatch

Do you have any suggestions about what I should change or look for to 
find my error?

Ok, we'll need to look at a more general solution for that.

Ok, thanks.  I'll try and look at adding these, but can't promise when.

Thanks for the information.  BTW, can you please send mails in plain text format.  This one was pretty hard to read.

Resending in plain text:

I was using java.net.NetworkInterface.getHardwareAddress() to get the 
MAC address. Work around is a JNI call (currently Windows only).

I was using ResourceBundle.keySet() and ResourceBundle.containsKey()

HTH,

This is because you're mixing -findirect-dispatch and
-fno-indirect-dispatch, which doesn't work.  Compile the executable
with -findirect-dispatch too.

Andrew.

Re: link error: undefined reference

[Keith]

Thank you very much. I feel like an idiot. Obviously I've been away from 
gcc too long and forgot to keep my compile flags consistent.

Just FYI, compiling under Windows XP, SP3, using gcj 4.4.0, mingw, and msys

When I compile with -O0 -m32 -fjni -findirect-dispatch
using gcj 4.4.0, I get
gcj: unrecognized option '-s-bc-abi'
for some files. It seems to do no harm.

$ cat Test.java
class Test {
    public static void main(String[] args)
    {
        System.out.println("Sample message");
    }
}

$ sh -x make-test.sh
+ C_FLAGS='-O0 -m32 -findirect-dispatch'
+ gcj -O0 -m32 -findirect-dispatch -C Test.java
gcj.exe: unrecognized option '-s-bc-abi'
+ gcj -O0 -m32 -findirect-dispatch -o Test.exe Test.class --main=Test 
-Wl,--enable-auto-import

$ ./Test.exe
Simple message


$ sh -x make-test.sh
+ C_FLAGS='-O0 -m32'
+ gcj -O0 -m32 -C Test.java
+ gcj -O0 -m32 -o Test.exe Test.class --main=Test -Wl,--enable-auto-import

$ ./Test.exe

This application has requested the Runtime to terminate it in an unusual 
way.

It's just complaining that indirect-dispatch makes no sense when
compiling .java to .class.  It doesn't matter.

Sorry, dunno.  It should work, but I don't have a Windows system.

Did you run the gcj test suite?

Andrew.
