Adding new tests in R-package/tests/testthat is a valuable way to improve the reliability of the R package.The devtools package also includes the installgitorious, installbitbucket, and installurl functions for installing packages from other locations. Generally for R packages with C++ dependencies, this requires either installing system packages, which you may not have privileges to do, or building the C++ dependencies separately, which introduces all sorts of additional ways for things to go wrong.The R packages unit tests are run automatically on every commit, via integrations like GitHub Actions. On Linux, install.packages() retrieves a source package that has to be compiled locally, and C++ dependencies need to be resolved as well. Install.packages(pkgs, lib, repos getOption('repos'), contriburl contrib.url(repos, type), method, available NULL, destdir NULL, dependencies NA, type getOption('pkgType'), configure.args getOption('configure.args'), configure.vars getOption('configure.vars'), clean FALSE, Ncpus getOption('Ncpus', 1L), verbose getOption('verbose'), libsonly FALSE, INSTALLopts, quiet FALSE, keepoutputs FALSE, )On macOS and Windows, when you install.packages('arrow'), you get a binary package that contains ArrowвЂ™s C++ dependencies along with it.

Note also that if you use conda to manage your R environment, this document does not apply. If youвЂ™re contributing to the Arrow project, youвЂ™ll probably want to manage your C++ installation more directly. The intended audience for this document is arrow R package users on Linux, not developers. This document describes how it works and the options for fine-tuning Linux installation. This article describes how to satisfy these dependencies for Windows, Mac OS X and Debian/Ubuntu Linux.Our goal is to make install.packages('arrow') вЂњjust workвЂќ for as many Linux distributions, versions, and configurations as possible. LaTeX for building R manuals and vignettes.

Prebuilt binaries are built with this flag enabled, so you get the full functionality by using them as well.Both of these variables are also set this way if you have the NOT_CRAN=true environment variable set.If you already have arrow installed and want to upgrade to a different version, install a development build, or try to reinstall and fix issues with Linux C++ binaries, you can call install_arrow(). This will increase the build time but provides many useful features. Alternatively, you can set export LIBARROW_MINIMAL=falseTo build the Arrow libraries with optional features such as compression libraries enabled. To speed installation up, you can set export LIBARROW_BINARY=trueTo look for C++ binaries prebuilt for your Linux distribution/version.

If afterwards you install the missing system requirements, youвЂ™ll need to reinstall the package in order to enable S3 support.In order for the arrow R package to work, it needs the Arrow C++ library. If youвЂ™re building everything from source, the install script will check for the presence of these dependencies and turn off S3 support in the build if the prerequisites are not metвЂ“installation will succeed but without S3 functionality. OpenSSL >= 1.0.2: install openssl-devel (rpm) or libssl-dev (deb)The prebuilt C++ binaries come with S3 support enabled, so you will need to meet these system requirements in order to use themвЂ“the package will not install without them. CURL: install libcurl-devel (rpm) or libcurl4-openssl-dev (deb) gcc >= 4.9 or clang >= 3.3 note that the default compiler on CentOS 7 is gcc 4.8.5, which is not sufficient

Depending on your system, building Arrow C++ from source likely will be slow consequently, it is designed to happen only when you run install.packages('arrow') or R CMD INSTALL but not when running R CMD check, unless youвЂ™ve set the NOT_CRAN=true environment variable.For the mechanics of how all this works, see the R package configure script, which calls tools/nixlibs.R. If no matching source bundle is found, it will also look to see if you are in a checkout of the apache/arrow git repository and thus have the C++ source there. For a list of supported distributions and versions, see the arrow-r-nightly project.If no binary is found, it will download the Arrow C++ source that matches the R package version (CRAN release or nightly build) and attempt to build it locally.

However, if you are using Arrow libraries already on your system, version match isnвЂ™t guaranteed.To fix version mismatch, you can either update your system packages to match the R package version, or set the environment variable ARROW_USE_PKG_CONFIG=FALSE to tell the configure script not to look for system Arrow packages. When install.packages('arrow') has to download the C++ libraries, the install script ensures that you fetch the C++ libraries that correspond to your R package version. Because the Apache Arrow project is under active development, is it essential that versions of the C++ and R libraries match. This build script is also what is used to generate the prebuilt binaries.If a system library or other installed Arrow is found but it doesnвЂ™t match the R package version (for example, you have libarrow 1.0.0 on your system and are installing R package 2.0.0), it is likely that the R bindings will fail to compile.

That should guarantee that the compiler settings match.If a prebuilt binary wasnвЂ™t found for your operating system but you think it should have been, check the logs for a message that says *** Unable to identify current OS/version, or a message that says *** No C++ binaries found for an invalid OS. This is likely a compiler mismatch and may be resolvable by setting some environment variables to instruct R to compile the packages to match the C++ library.A workaround would be to set the environment variable LIBARROW_BINARY=FALSE and retry installation: this value instructs the package to build the C++ library from source instead of downloading the prebuilt binary. Similarly, if youвЂ™re using Arrow system libraries, running update.packages() after a new release of the arrow package will likely fail unless you first update the system packages.If the R package finds and downloads a prebuilt binary of the C++ library, but then the arrow package canвЂ™t be loaded, perhaps with вЂњundefined symbolsвЂќ errors, please report an issue.

This table is checked during the installation process and tells the script to use binaries built on a different operating system/version because theyвЂ™re known to work. Setting LIBARROW_BINARY is also an option when thereвЂ™s not an exact match for your OS but a similar version would work, such as if youвЂ™re on ubuntu-18.10 and thereвЂ™s only a binary for ubuntu-18.04.If that workaround works for you, and you believe that it should work for everyone else too, you may propose adding an entry to this lookup table. You may also set the environment variable ARROW_R_DEV=TRUE for additional debug messages.A workaround would be to set the environment variable LIBARROW_BINARY to a distribution-version that exists in the Ursa Labs repository.
