Hi,
This ought to be in the FAQ but I couldn't find it. I can't seem to get
a hello world program to work as an executable though it works fine with the
JVM. I've seen this asked before but not the answer. See code below.
Hello.java (note: case is important in this filename)
==========
class Hello {
public Hello() {};
public static void main(String args[]) {
int returnCode = 0;
System.out.println("hello world\r\n");
System.exit(returnCode);
}
}
Makefile
========
JAVAC = gcj
JFLAGS = -gstabs
all: Hello.class Hello.exe test
test:
java Hello
.\Hello
%.class: %.java
$(JAVAC) $(JFLAGS) -C $<
# note: this will not link unless you install libiconv
# using the standard cygwin installer
%.exe: %.java
$(JAVAC) --main=Hello $(JFLAGS) $< -o $@
Output
======
C:\BruceA\java>make
gcj -gstabs -C Hello.java
gcj --main=Hello -gstabs Hello.java -o Hello.exe
java Hello
hello world
.\Hello
7 [main] Hello 284 handle_exceptions: Exception:
STATUS_ACCESS_VIOLATION
33835 [main] Hello 284 open_stackdumpfile: Dumping stack trace to
Hello.exe.st
Ackdump
What have I done wrong?
Regards,
Bruce A.
