創建使用RcppArmadillo的軟件包

Question

我已經使用RcppArmadillo和內聯軟件包編寫函數，我使用的是Windows 7，安裝了R-2.14.1和Rtools215並檢查了路徑。

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'

有關如何解決問題的任何建議。

Answer 1

您需要使用Rcpp提供的package.skeleton變體，或者在本例中使用RcppArmadillo。也就是說，調用

RcppArmadillo.package.skeleton(...) 

不是一個從基R.
