gcc version 4.0.0 20041113 (experimental)
I produce a cross compiler as I normally do. Host is linux, target is
i686-pc-mingw32, and create a simple test class and compile:
public class test {
public static void main(String[] sa) {
System.out.println("H. World");
}
}
i686-pc-mingw32-gcj --main=test test.java
Copy the a.exe to a win machine, run it, and it has an application error. All
.exe's that are created with gcj fail.
If I create a "hello world" test.c and compile it with i686-pc-mingw32-gcc, and
copy it to the win box it works fine.
The i686-pc-mingw32-gcj I built a month ago works without problem:
gcc version 4.0.0 20041014 (experimental)
Here is what I see in gdb:
