當我在R中使用Rcpp時，包含boost的編譯錯誤

Question

盡管我已經有了RTools和BH軟件包，但出現了以下錯誤。 （我使用的是Win10 64位和R 3.5.1）

當我編譯其他軟件包時，Rtools效果很好。

我已經看過許多相關的問答，但無法解決此問題。

請幫助這個新手。

通過編譯命令，我們可以了解到您沒有包括BH包中的boost標頭：

c:/Rtools/mingw_64/bin/g++  -std=gnu++11 -I"C:/PROGRA~1/R/R-35~1.1/include"
 -DNDEBUG   -I"C:/Users/CEO/Documents/R/win-library/3.5/Rcpp/include" 
 -I"D:/Data/Drive/RCodes/scRNA-seq/TransSyn"        -O2 -Wall  -mtune=generic -c
 TransSyn.cpp -o TransSyn.o

缺少-I"C:/Users/CEO/Documents/R/win-library/3.5/BH/include" 。 您可以通過添加來解決此問題

// [[Rcpp::depends(BH)]]

到D:/Data/Drive/RCodes/scRNA-seq/TransSyn/TransSyn.cpp 當然，您必須確保已安裝BH 。
