Create a source bundle that includes all thirdparty dependencies

## Usage

create_package_with_all_dependencies(dest_file = NULL, source_file = NULL)

## Arguments

dest_file

File path for the new tar.gz package. Defaults to arrow_V.V.V_with_deps.tar.gz in the current directory (V.V.V is the version)

source_file

File path for the input tar.gz package. Defaults to downloading the package from CRAN (or whatever you have set as the first in getOption("repos"))

## Value

The full path to dest_file, invisibly

This function is used for setting up an offline build. If it's possible to download at build time, don't use this function. Instead, let cmake

download the required dependencies for you. These downloaded dependencies are only used in the build if ARROW_DEPENDENCY_SOURCE is unset, BUNDLED, or AUTO. https://arrow.apache.org/docs/developers/cpp/building.html#offline-builds

If you're using binary packages you shouldn't need to use this function. You should download the appropriate binary from your package repository, transfer that to the offline computer, and install that. Any OS can create the source bundle, but it cannot be installed on Windows. (Instead, use a standard Windows binary package.)

Note if you're using RStudio Package Manager on Linux: If you still want to make a source bundle with this function, make sure to set the first repo in options("repos") to be a mirror that contains source packages (that is: something other than the RSPM binary mirror URLs).

### Steps for an offline install with optional dependencies:

#### Using a computer with internet access, pre-download the dependencies:

• Install the arrow package or run source("https://raw.githubusercontent.com/apache/arrow/master/r/R/install-arrow.R")

• Run create_package_with_all_dependencies("my_arrow_pkg.tar.gz")

• Copy the newly created my_arrow_pkg.tar.gz to the computer without internet access

#### On the computer without internet access, install the prepared package:

• Install the arrow package from the copied file

• install.packages("my_arrow_pkg.tar.gz", dependencies = c("Depends", "Imports", "LinkingTo"))

• This installation will build from source, so cmake must be available

• Run arrow_info() to check installed capabilities

## Examples

if (FALSE) {
new_pkg <- create_package_with_all_dependencies()
# Note: this works when run in the same R session, but it's meant to be
# copied to a different computer.
install.packages(new_pkg, dependencies = c("Depends", "Imports", "LinkingTo"))
}
