LINUX编译OPENJDK：The tested number of bits in the target (0) differs from the number of bits expected

• 错误：

The tested number of bits in the target (0) differs from the number of bits expected to be found in the target

• 解决办法：

1、使用新的JDK版本。我现在编译已经没有这个错误了。

2、编译时指明64位。参数是：--with-target-bits=64

3、修改配置文件。

打开common/autoconf/generated-configure.sh，搜索这个语句，把判断语句用到的两个变量改为64即可。如：

      TESTED_TARGET_CPU_BITS=`expr 8 \* $ac_cv_sizeof_int_p`# 加上这一句
TESTED_TARGET_CPU_BITS=64if test "x$TESTED_TARGET_CPU_BITS" != "x$OPENJDK_TARGET_CPU_BITS"; thenas_fn_error $? "The tested number of bits in the target ($TESTED_TARGET_CPU_BITS) differs from the number of bits expected to be found in the target ($OPENJDK_TARGET_CPU_BITS)" "$LINENO" 5fi
