Subject: The method exit(int) is undefined for the type of System, when build
gcj on mips64el
Message-ID: <e786105a1003150442p9f54de5ia4c7e84b4154f76d@mail.gmail.com>
hi,
I'm trying to port OpenJDK to mips64el,but have some troubles,and didn't
know where is the source problem.
Here are my steps:
1, build gcj. The version of gcc is 4.4.1, and configure like the follows:
*../configure --prefix=/usr --build=mips64el-linux \
--disable-nls --enable-shared --enable-__cxa_atexit \
--disable-multilib --with-abi=64 \
--with-ecj-jar=/usr/share/java/ecj.jar \
--enable-c99 --enable-long-long --enable-threads=posix \
--enable-languages=java*
the ecj.jar is copied from my PC(x86_64), and version of 4.5.
2, compile Classpath-0.98 with gcj
*export MABI=64
../configure --prefix=/usr --build=mips64el-linux \
--disable-plugin*
but failed when configure, the error from config.log is:
*error: The method exit(int) is undefined for the type of System
System.exit(0);*
then I write a simple test program:
*// test.java
public class test{
public static void main(String args[]){
System.out.print("Hello world");
System.exit(0);
}
}*
and the error is the same as above.
3, then I tried "make check" in the directory of libjava. Here are the last
lines of libjava.log:
*PASS: TestParent compilation from source

I wonder if my steps is correct, so I need your help. Can you give me some
tips, or tell me how debian's openjdk was built on mipsel?
Waiting for reply. Thanks!
