mac中Rcpp包中的dyn.load错误

我在加载编译对象Rcpp编译对象时遇到问题.我从源代码编译RcppSMC包.一世

Error in dyn.load("mylib.so") : 
  unable to load shared object '/Users/avi/softwares/RcppSMC/src/mylib.so': 
  dlopen(/Users/avi/softwares/RcppSMC/src/mylib.so, 6): Symbol not found: __ZNSoD0Ev
  Referenced from: /Users/avi/softwares/RcppSMC/src/mylib.so
  Expected in: flat namespace
 in /Users/avi/softwares/RcppSMC/src/mylib.so 

我正在使用clang进行以下编译的编译.我认为有一些编译问题,因为如果我从CRAN dyn.load下载mac os二进制文件.

安装到/Users/avi/Library/R/3.0/library/RcppSMC/libs

这是一个奇怪的问题,因为sourceCpp正在机器中工作.
