我今天刚刚将RcppArmadillo更新为0.4.100.2.1。我正在开发一个项目，我使用RcppArmadillo加速一些设计矩阵计算。但是，在更新到0.4.100.2.1之后，R将不再编译我的.cpp文件，并且收到大量错误消息：

该文件使用旧版本的RcppArmadillo编译（不记得版本，但可能从2013年11月左右开始）。我在运行OS 10.9的MacBook pro上使用R.
我不明白为什么在错误消息中提到了randi，因为我没有做任何随机数生成。
非常感谢任何帮助！
干杯亚当
更新：正如我所说的那样，旧版本的Rcpp / RcppArmadillo似乎没有问题（昨天我从2013年6月左右开始安装版本并且能够编译我的.cpp文件）。现在，当我安装第一个当前的Rcpp 0.11.0时，一切看起来都很正常。然后安装当前的RcppArmadillo 0.4.100.2.1后，我收到警告：
* installing *source* package ‘RcppArmadillo’ ...
** package ‘RcppArmadillo’ successfully unpacked and MD5 sums checked
* checking LAPACK_LIBS divide-and-conquer complex SVD unavailable via R-supplied LAPACK
* divide-and-conquer algorithm for complex SVD will be redirected to default

所以RcppArmadillo安装，但警告仍然存在。事实上，警告类似于昨天发布的警告。我不明白这些警告，我仍然无法编译我的（以前可编译的）.cpp文件。最后，我能够编译不依赖于RcppArmadillo的.cpp文件，所以我认为这实际上是一个RcppArmadillo问题。
编辑：我的.cpp文件现在编译，但警告仍在那里。我被告知它可能与最近的犰狳更新有关 - 所以不是Rcpp / RcppArmadillo问题！
