在Debian、Ubuntu和Linux Mint 64位系统中，尝试链接libv8时遇到错误：undefined reference to icu_46。解决方法可能包括在编译V8时禁用国际化选项。

debian, ubuntu, linux mint 64位链接 libv8 出错 undefined reference to icu_46

==================================================

出错情形：

使用google document自带的例子

g++ -Iinclude hello_world.cc -o hello_world out/x64.release/obj.target/tools/gyp/libv8_{base.x64,snapshot}.a -lpthread

报如下错误

collect2: error: ld returned 1 exit status

出错原因：

某些地方国际化做得不好，一开始可以考虑只是用非国际化的v8版本，在编译v8时加选项取消国际化。

make -j4 native i18nsupport=off werror=no
