如何修复bug？

Question

Undefined symbols for architecture armv7:
"operator delete(void*)", referenced from:
  AES::~AES() in libusc.a(AES.o)
"___gxx_personality_sj0", referenced from:
  _decyptToken in libusc.a(tokenWrap.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我在项目中使用静态库，静态库支持armv7。
