下载源码

# 经常失败
hg clone http://hg.openjdk.java.net/jdk8u/jdk8u-dev/

建议早上下载github，非常快：

https://github.com/AdoptOpenJDK/openjdk-jdk8u

修改脚本gcc.make

hotspot/make/bsd/makefiles/gcc.make

注释：

# Compiler warnings are treated as errors
# ifneq ($(COMPILER_WARNINGS_FATAL),false)
#   WARNINGS_ARE_ERRORS = -Werror
# endif

注释：

# ifeq ($(USE_CLANG),)
#   ifneq ($(CC_VER_MAJOR), 2)
#     DEPFLAGS += -fpch-deps
#   endif
# endif

加上：

LFLAGS += -stdlib=libstdc++

修改脚本generate-config.sh

common/autoconf/generate-config.sh

搜索compiler is required，全部注释相应的语句。

搜索gnu++，注释。
