How to generate Bitcoin Gold raw transaction

I can not generate valid raw transaction. Anyone know how to properly use ForkID ?

Code:

public static int calcSigHashValue(SigHash mode, boolean anyoneCanPay) {
Preconditions.checkArgument(SigHash.ALL == mode || SigHash.NONE == mode || SigHash.SINGLE == mode);
int sighashFlags = mode.value;
if(anyoneCanPay) {
sighashFlags |= SigHash.ANYONECANPAY.value;
}

return sighashFlags |= SigHash.FORK_ID.value;
}

public static int calcSigHashValue(SigHash mode, boolean anyoneCanPay, boolean forkid) {
Preconditions.checkArgument(SigHash.ALL == mode || SigHash.NONE == mode || SigHash.SINGLE == mode);
int sighashFlags = mode.value;
if(anyoneCanPay) {
sighashFlags |= SigHash.ANYONECANPAY.value;
}

if(forkid) {
sighashFlags |= SigHash.FORK_ID.value;
}

return sighashFlags;
}

and answer is:

Code:

mandatory-script-verify-flag-failed (Signature must be zero for failed CHECK(MULTI)SIG operation)
