我有一个用theos新建的一个app工程，想混淆加密一下代码，在论坛和网上搜索了一些方法，发现现有的方案llvm-obfuscator
使用 obfuscator-llvm 的 clang 去编译程序，后面添加响应的参数就可以实现混淆，于是我修改Makefile模板如下：
TARGET_CC = /Users/admin/work/tools/obfuscator/build/bin/clang
TARGET_CXX = /Users/admin/work/tools/obfuscator/build/bin/clang
TARGET_LD = /Users/admin/work/tools/obfuscator/build/bin/clang
_THEOS_TARGET_CFLAGS += -mllvm -fla -mllvm -sub
_THEOS_TARGET_CXXFLAGS += -mllvm -fla -mllvm -sub
编译工程已有的代码都没有问题，我代码里加入了高德地图的SDK，进行链接的时候报错：

基础实在太差，不知道是遗漏了什么还是有别的需要注意的地方，请求大家帮忙！
