创建使用RcppArmadillo的包

Question

我使用RcppArmadillo和内联包编写函数，我使用的是Windows 7，R-2.14.1和Rtools215，并检查路径。

funs = cxxfunction(list(MHcpp = signature(…), IWcpp = signature(…),  c(code1,code2), 
plugin="RcppArmadillo" ) # No compline and I they work fine as expected.

Package.skeleton(“new”,funs) # to create the package skeleton and the dynamic libray
# to build the package  I use
R CMD INSTALL –build new # I get the following error
C:/Users/samuel/Documents/R/win-library/2.14/Rcpp/lib/i386/libRcpp.a(Dimension.o
):Dimension.cpp:(.text+0x342): undefined reference to `_Unwind_SjLj_Unregister'

collect2: ld returned 1 exit status
ERROR: compilation failed for package 'new'

有关如何解决问题的任何建议。

Answer 1

您需要使用Rcpp提供的package.skeleton变体，或者在这种情况下，使用RcppArmadillo。也就是说，打电话

 RcppArmadillo.package.skeleton(...)

不是来自基地R的那个。

您还可以查看依赖于RcppArmadillo的其他CRAN包是如何组织的，并比较差异。
