我正在运行ubuntu，64位。我有这个最小的测试包 我学习如何做这些事情（我正在关注这个tutorial，除了我在包中也有一些c代码）。我跑的时候
R CMD check MySmallPackage
就可以了，它运作正常（见下文）。然后， 我跑
R CMD build MySmallPackage
它也有效（见下文）。所以现在，我发送 由此产生的.tar.gz给一个运行win7 64位的朋友 （和64位R），他收到此错误消息：
*** arch - i386
ERROR: compilation failed for package 'MySmallPackage'
* removing 'C:/Users/ES/Documents/R/win-library/2.15/MySmallPackage'
Warning in install.packages :

Warning in install.packages :
installation of package ‘C:/Users/ES/Downloads/MySmallPackage_0.1.1(1).tar.gz’ had non-zero exit status
非常令人费解。任何人都可以指出可能导致这个问题的原因（我多年没有使用过Windows，但是在linux上安装包很好）。错误信息对我来说有点神秘。
