我正在使用 Windows 并且刚刚更新到R 4.0.3（使用RStudioto 1.3.959）并R检查了我使用的一个包，Rcpp并且RcppArmadillo我得到了以下注意事项：
> checking compiled code ... NOTE
Note: information on .o files for i386 is not available
Note: information on .o files for x64 is not available
File 'C:/Users/NIR_Workstation/Documents/GitHub/prospectr.Rcheck/prospectr/libs/i386/prospectr.dll':
Found 'abort', possibly from 'abort' (C), 'runtime' (Fortran)
Found 'exit', possibly from 'exit' (C), 'stop' (Fortran)

Found 'abort', possibly from 'abort' (C), 'runtime' (Fortran)
Found 'exit', possibly from 'exit' (C), 'stop' (Fortran)
Found 'printf', possibly from 'printf' (C)
当我在R 4.0.2. 我试图找出我的包裹里发生了什么，但没有成功。
我也试过这个（用R 4.0.3）：
Rcpp::Rcpp.package.skeleton("aTest", example_code = TRUE)
rcmdcheck::rcmdcheck(error_on = "warning", check_dir = "check")
我得到了与我的包的一个输出相同类型的 NOTE。同样，R 4.0.2此 NOTE 不输出。
关于这个注意的任何想法？或者至少对我可以尝试找出发生了什么事情的任何建议？
提前致谢。
更新的问题：
我想在更新我的问题之前进行额外的测试。
他们来了：
R 4.0.3我在其他几台 Windows 机器上进行了全新安装rtools，RStudio以及devtools运行以下示例所需的包（没有预编译的对象）。我设法使用 reprex()来重现我为另一个模板包创建的注释Rcpp.package.skeleton()：
mdir <- "./my_dir"
dir.create(mdir)
setwd("./my_dir")
Rcpp::Rcpp.package.skeleton("anotherTest", example_code = TRUE)

除了上述测试之外，我还运行了相同的代码：
R 4.0.3和rtools35R 4.0.2和rtools40R 4.0.3在 Linux (x86_64-pc-linux-gnu (64-bit))
对于这三个测试，检查干净地通过了。
总之，问题只出现R 4.0.3with rtools40。假设问题来自于是否正确rtools40？如果是这样，对 CRAN 检查/提交有什么影响？
谢谢
