我如何查看和复制R默认的Makevars配置?

问题描述

我没有〜/.R/Makevars 文件和

> tools::makevars_user()
character(0)
> tools::makevars_site()
character(0)

但是， R 必须从某处读取配置，因为包含 Rcpp 的 .cpp 文件在软件包 src中导出了子目录编译正常.

Yet, R must be reading the configuration from somewhere as .cpp files containing Rcpp exports in the package src subdirectory compile fine.

我很想知道如何在 src 目录中编写 Makefile.win ，以便使 Rcpp 文件与 TMB .cpp 文件.当前的生成文件如下:

I am interested to know how to write a Makefile.win in the src directory so that Rcpp files continue to compile, alongside TMB .cpp files. Currently a makefile like:

all: fn1.dll fn2.dll

fn1.dll: fn1.cpp
    Rscript --vanilla -e "TMB::compile('fn1.cpp')"

fn2.dll: fn2.cpp
    Rscript --vanilla -e "TMB::compile('fn2.cpp')"

clean:
    rm -rf *o

可以很好地编译 TMB 文件，并且实际上由以下建议: https://github.com/kaskr/adcomp/issues/43

works fine to compile TMB files, and is in fact suggested by: https://github.com/kaskr/adcomp/issues/43

我试图修改Dirk在此处建议的 makefile ，但没有运气可复制 R 的默认行为，即使使用了新的测试包也是如此.

I tried to modify the makefile suggested by Dirk here but had no luck to replicate R's default behaviour even with a fresh new test package.

我的会话信息:

> sessionInfo()
R version 3.3.2 (2016-10-31)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 7 x64 (build 7601) Service Pack 1

推荐答案

我仍然不知道如何使用 Makevars 来做我想做的事，本质上是:

I still have no idea how to use Makevars to do what I want, which is to essentially:

1. 通过 Build and Reload 包在Rstudio(Windows 7)中对所有 Rcpp 导出文件执行正常的默认 make .在后台，此调用 Rcpp :: compileAttributes()，然后继续运行其他程序包构建命令.
2. 使用Rstudio Build and Reload 进行另一个 make ，除了现在它读取仅编译 TMB Makefile >代码.

1. Do a normal default make in Rstudio (Windows 7) via Build and Reload package for all Rcpp export files. Under the hood, this calls Rcpp::compileAttributes() then proceeds to run the other package building commands.
2. Do another make using Rstudio Build and Reload, except now it reads the Makefile that only compiles the TMB code.

但是，我确实有一种解决方法.本质上， R扩展手册指出:

However, I do have a work-around. Essentially, the R extensions manual states that:

...

由于，用于编译 TMB .cpp 文件的代码只是 R 命令，因此将它们集成到这样的目录中很容易文件:

Since, the code to compile the TMB .cpp files are simply R commands, it is easy enough to integrate them into such a file:

# replicate default R
files <- Sys.glob(paste("*", SHLIB_EXT, sep=''))
libarch <- if (nzchar(R_ARCH)) paste('libs', R_ARCH, sep='') else 'libs'
dest <- file.path(R_PACKAGE_DIR, libarch)
dir.create(dest, recursive = TRUE, showWarnings = FALSE)
file.copy(files, dest, overwrite = TRUE)

# now do TMB files
cpp_files <- list.files('./TMB/', full.names = T, pattern = '*.cpp')

for (f in cpp_files) {
    TMB::compile(f)
}

files <- Sys.glob(paste("./TMB/*", SHLIB_EXT, sep=''))
libarch <- if (nzchar(R_ARCH)) paste('libs', R_ARCH, sep='') else 'libs'
dest <- file.path(R_PACKAGE_DIR, libarch)
dir.create(dest, recursive = TRUE, showWarnings = FALSE)
file.copy(files, dest, overwrite = TRUE)

此文件读取并编译存储在子目录< pkgdir>/src/TMB 中的所有 TMP 类型的 .cpp 文件.，然后将< pkgdir>/src/和&p; pkgdir>/src/TMB 中的所有后续 .dll 复制到安装中软件包的目录.

This file reads and compiles all TMP type .cpp files, stored in the sub-directory <pkgdir>/src/TMB, and then copies all subsequent .dlls in <pkgdir>/src/ and <pkgdir>/src/TMB to the installation directory of the package.

请注意，这是可能的，但可能非常困难使用 Makevars 来获取将TMB文件存储在子目录中时完成编译.Dirk在矩阵包中推荐了该示例，但我有修改在那里的代码以执行我想要的操作是没有运气的.

Note, it is possible, but possibly very difficult to use Makevars to get a compilation done when the TMB files are stored in a subdirectory. Dirk recommended the example in the matrix package, but I had no luck modifying the code there to do what I want.
