[英]Installing R on OSX Big Sur (EDIT: and Apple M1) for use with Rcpp and openMP
There's probably a gazillion threads on OSX+Rcpp+openMP, but the bottom line right now appears to be this (per coatless ): OSX+Rcpp+openMP 上可能有无数个线程,但现在的底线似乎是这个( percoatless ):
Unfortunately, with R 4.0.0 the CRAN distributed version of R loses the ability to use OpenMP without a custom setup.
不幸的是,在 R 4.0.0 中,R 的 CRAN 分布式版本失去了在没有自定义设置的情况下使用 OpenMP 的能力。
I came across other ideas, including compiling llvm yourself, using homebrew or macports to install R and/or llvm and/or gcc, and then figuring out how to use the right compiler and/or flags with (R)cpp.我遇到了其他想法,包括自己编译llvm ,使用homebrew或macports安装 R 和/或 llvm 和/或 gcc,然后弄清楚如何使用正确的编译器和/或带有 (R)cpp 的标志。 However, I find this all very confusing.
然而,我觉得这一切都非常令人困惑。
I am not a mac user, but it seems to me that setting up a mac to compile Rcpp packages or code snippets with openMP seems to be too difficult for most mac users.我不是 mac 用户,但在我看来,设置 mac 以使用 openMP 编译 Rcpp 包或代码片段对于大多数 mac 用户来说似乎太困难了。 However, I would like my R package on github to be used by more users, and since it relies on openMP, I am losing that audience.
但是,我希望我在 github 上的 R 包被更多用户使用,而且由于它依赖于 openMP,我正在失去那些观众。
Can someone provide the necessary steps to set up R on mac in a way that it can compile Rcpp code with openMP?有人可以提供必要的步骤来在 mac 上设置 R 以使用 openMP 编译 Rcpp 代码吗? I'd like to turn that into a quick tutorial.
我想把它变成一个快速教程。
EDIT: I should have added - on Apple Silicon, because there are some extra confusions where things go - /usr/local
vs /opt
编辑:我应该添加 - 在 Apple Silicon 上,因为有一些额外的混乱 -
/usr/local
vs /opt
I spent a day figuring this out (original post here );我花了一天的时间来解决这个问题(原帖在这里); here are the steps I used to compile R packages from source with openMP:
以下是我使用 openMP 从源代码编译 R 包的步骤:
# To delete an existing command line tools installation:
sudo rm -rf /Library/Developer/CommandLineTools
# To install the command line tools
sudo xcode-select --install
# WARNING: This can take several hours
brew install gcc
brew cleanup
brew update
brew upgrade
brew reinstall gcc
sudo ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/* /usr/local/include/
# You can ignore warnings like this:
#ln: /usr/local/include//tcl.h: File exists
#ln: /usr/local/include//tclDecls.h: File exists
#ln: /usr/local/include//tclPlatDecls.h: File exists

#ln: /usr/local/include//tkPlatDecls.h: File exists
cd /usr/local/gfortran/lib/gcc/x86_64-apple-darwin19/; ls
) then edit your ~/.R/Makevars
file (if you don't have a file called Makevars
in your ~/.R/
directory) and include only these lines:cd /usr/local/gfortran/lib/gcc/x86_64-apple-darwin19/; ls
)然后编辑您的~/.R/Makevars
文件(如果您的文件中没有名为Makevars
的文件) ~/.R/
目录)并仅包含以下~/.R/
行:LOC = /usr/local/gfortran
CC=$(LOC)/bin/gcc -fopenmp
CXX=$(LOC)/bin/g++ -fopenmp
CXX11 = $(LOC)/bin/g++ -fopenmp
CFLAGS=-g -O3 -Wall -pedantic -std=gnu99 -mtune=native -pipe
CXXFLAGS=-g -O3 -Wall -pedantic -std=c++11 -mtune=native -pipe
LDFLAGS=-L$(LOC)/lib -Wl,-rpath,$(LOC)/lib
CPPFLAGS=-I$(LOC)/include -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include
# (check that the version of gfortran - in this case 10.2.0 - matches the version specified in FLIBS)
FLIBS=-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin19/10.2.0 -L/usr/local/gfortran/lib -lgfortran -lquadmath -lm
CXX1X=/usr/local/gfortran/bin/g++
CXX98=/usr/local/gfortran/bin/g++
CXX11=/usr/local/gfortran/bin/g++
CXX14=/usr/local/gfortran/bin/g++
CXX17=/usr/local/gfortran/bin/g++
install.packages("data.table")
Unfortunately, I do not believe a more "simple" setup exists.不幸的是,我不相信存在更“简单”的设置。
Eventually, I found a process that works on a M1 mac with Big Sur.最终,我找到了一个可以在带有 Big Sur 的M1 mac上运行的过程。
R-4.1-branch.pkg
.R-4.1-branch.pkg
下载并安装 R。 The CRAN version might also work, but I used the installer from mac.r-project.org, which required opening the osx security settings to allow the installation. sudo xcode-select --install
in Terminal.sudo xcode-select --install
。openmp-11.0.1-darwin20-Release.tar.gz
and install it (see Terminal commands below).openmp-11.0.1-darwin20-Release.tar.gz
并安装它(参见下面的终端命令)。curl -O https://mac.r-project.org/openmp/openmp-11.0.1-darwin20-Release.tar.gz
sudo tar fvx openmp-11.0.1-darwin20-Release.tar.gz -C /
Makevars
file.Makevars
文件。cd ~
mkdir .R
nano .R/Makevars
in nano, paste these additional compiler flags into the Makevars
file:在 nano 中,将这些额外的编译器标志粘贴到
Makevars
文件中:
CPPFLAGS += -Xclang -fopenmp
LDFLAGS += -lomp
Hit Control+O, Control+X to save and close按 Control+O、Control+X 保存并关闭
gfortran-ARM-11.0-BigSur.pkg
to install gfortran .gfortran-ARM-11.0-BigSur.pkg
安装 gfortran 。/usr/local/gfortran
, but R expects it in /opt
./usr/local/gfortran
,但 R 期望它安装在/opt
。 The mac-R team likes to separate arm64 and intel related files. /opt
./opt
下安装 gfortran。 Download the tar file gfortran-ARM-11.0-BigSur.tar.xz
.gfortran-ARM-11.0-BigSur.tar.xz
。 You can use curl, or just download it and point tar in the command line to it.cd /opt/R/arm64/
sudo mkdir gfortran
sudo tar -xzyf gfortran-ARM-11.0-BigSur.tar.xz -C /opt/R/arm64/
(replace gfortran-ARM-11.0-BigSur.tar.xz
with /users/YOURUSERNAME/downloads/gfortran-ARM-11.0-BigSur.tar.xz
) (用
gfortran-ARM-11.0-BigSur.tar.xz
替换gfortran-ARM-11.0-BigSur.tar.xz
/users/YOURUSERNAME/downloads/gfortran-ARM-11.0-BigSur.tar.xz
)
Now it should work.现在它应该可以工作了。
Not an expert in OSX, but doing this so others can figure out how to use my R package.不是 OSX 专家,但这样做是为了让其他人可以弄清楚如何使用我的 R 包。 I'd like to streamline the process some more, but wiping the mac, reinstalling osx and testing it takes so much time.
我想进一步简化这个过程,但是擦拭 mac、重新安装 osx 并测试它需要很多时间。
