Rcpp、Rtools 和 cygwin：无法安装 Rcpp

Question

First try, within cygwin with R 3.1.3 installed:

>PATH=/usr/local/bin:/usr/bin

In R:

>install.packages("Rcpp",repos="http://cran.us.r-project.org")

yields an error

[...]

make: *** [Rcpp.dll] Error 1
ERROR: compilation failed for package ‘Rcpp’
* removing ‘/usr/lib/R/site-library/Rcpp’

So I try installing Rtools 3.2. As instructed for cygwin install, I don't install cygwin's dll that are included in Rtools. Then

>PATH=/cygdrive/c/Rtools/bin:/cygdrive/c/Rtools/gcc-4.6.3/bin:$PATH

which, in R, yields a silent non-zero status exit when trying to do the installation

The downloaded source packages are in

Warning message:

Verbose mode is not more informative. I searched a long time, but I am at a loss now. Somebody has an idea? Thanks

Answer 1

I was getting frustrated dealing with the same errors. In the Cygwin installation 'Select Packages' window, search for each of these libraries and install them. For example: pcre, lzma, bz2, ... I was finally able to compile after installing all of these.

Answer 2

Unless you have a specific reason to use 3.1.3, update your R to the latest version (3.2.1).

Many packages don't even have Windows binaries compiled for anything but the most recent R release, so 99% of the time, that solves the issue.

If all you're trying to do is to install Rcpp try:

install.packages("Rcpp", type='source')

Answer 3

Cygwin is not supported by R itself, and was never supported.

Edit exactly five years later: As someone just saw fit to downvote this answer once more, allow me to quote Section C.7 of the R Installation and Administration manual

C.7 Cygwin

The 32-bit version never worked well enough to pass R's make check, and residual support from earlier experiments was removed in R 3.3.0.

The 64-bit version was never supported.

I have little more to add. I just re-stated what R Core says about their own software in their own manual.
