Building Arrow C++¶
System setup¶
Arrow uses CMake as a build configuration system. We recommend building out-of-source. If you are not familiar with this terminology:
In-source build:
cmake
is invoked directly from thecpp
directory. This can be inflexible when you wish to maintain multiple build environments (e.g. one for debug builds and another for release builds)Out-of-source build:
cmake
is invoked from another directory, creating an isolated build environment that does not interact with any other build environment. For example, you could createcpp/build-debug
and invokecmake $CMAKE_ARGS ..
from this directory
Building requires:
A C++11-enabled compiler. On Linux, gcc 4.8 and higher should be sufficient. For Windows, at least Visual Studio 2015 is required.
CMake 3.2 or higher
On Linux and macOS, either
make
orninja
build utilities
On Ubuntu/Debian you can install the requirements with:
sudo apt-get install \
build-essential \
cmake
On Alpine Linux:
apk add autoconf \
bash \
cmake \
g++ \
gcc \
make
On macOS, you can use Homebrew.
git clone https://github.com/apache/arrow.git
cd arrow
brew update && brew bundle --file=cpp/Brewfile
On MSYS2:
pacman --sync --refresh --noconfirm \
ccache \
git \
mingw-w64-${MSYSTEM_CARCH}-boost \
mingw-w64-${MSYSTEM_CARCH}-brotli \
mingw-w64-${MSYSTEM_CARCH}-cmake \
mingw-w64-${MSYSTEM_CARCH}-gcc \
mingw-w64-${MSYSTEM_CARCH}-gflags \
mingw-w64-${MSYSTEM_CARCH}-glog \
mingw-w64-${MSYSTEM_CARCH}-gtest \
mingw-w64-${MSYSTEM_CARCH}-lz4 \
mingw-w64-${MSYSTEM_CARCH}-protobuf \
mingw-w64-${MSYSTEM_CARCH}-python3-numpy \
mingw-w64-${MSYSTEM_CARCH}-rapidjson \
mingw-w64-${MSYSTEM_CARCH}-snappy \
mingw-w64-${MSYSTEM_CARCH}-thrift \
mingw-w64-${MSYSTEM_CARCH}-zlib \
mingw-w64-${MSYSTEM_CARCH}-zstd
Building¶
The build system uses CMAKE_BUILD_TYPE=release
by default, so if this
argument is omitted then a release build will be produced.
Note
You need to more options to build on Windows. See Developing on Windows for details.
Minimal release build:
git clone https://github.com/apache/arrow.git
cd arrow/cpp
mkdir release
cd release
cmake ..
make
Minimal debug build with unit tests:
git clone https://github.com/apache/arrow.git
cd arrow/cpp
mkdir debug
cd debug
cmake -DCMAKE_BUILD_TYPE=Debug -DARROW_BUILD_TESTS=ON ..
make unittest
The unit tests are not built by default. After building, one can also invoke
the unit tests using the ctest
tool provided by CMake (note that test
depends on python
being available).
On some Linux distributions, running the test suite might require setting an explicit locale. If you see any locale-related errors, try setting the environment variable (which requires the locales package or equivalent):
export LC_ALL="en_US.UTF-8"
Faster builds with Ninja¶
Many contributors use the Ninja build system to
get faster builds. It especially speeds up incremental builds. To use
ninja
, pass -GNinja
when calling cmake
and then use the ninja
command instead of make
.
Optional Components¶
By default, the C++ build system creates a fairly minimal build. We have
several optional system components which you can opt into building by passing
boolean flags to cmake
.
-DARROW_COMPUTE=ON
: Computational kernel functions and other support-DARROW_CSV=ON
: CSV reader module-DARROW_CUDA=ON
: CUDA integration for GPU development. Depends on NVIDIA CUDA toolkit. The CUDA toolchain used to build the library can be customized by using the$CUDA_HOME
environment variable.-DARROW_DATASET=ON
: Dataset API, implies the Filesystem API-DARROW_FILESYSTEM=ON
: Filesystem API for accessing local and remote filesystems-DARROW_FLIGHT=ON
: Arrow Flight RPC system, which depends at least on gRPC-DARROW_GANDIVA=ON
: Gandiva expression compiler, depends on LLVM, Protocol Buffers, and re2-DARROW_GANDIVA_JAVA=ON
: Gandiva JNI bindings for Java-DARROW_HDFS=ON
: Arrow integration with libhdfs for accessing the Hadoop Filesystem-DARROW_HIVESERVER2=ON
: Client library for HiveServer2 database protocol-DARROW_JSON=ON
: JSON reader module-DARROW_ORC=ON
: Arrow integration with Apache ORC-DARROW_PARQUET=ON
: Apache Parquet libraries and Arrow integration-DARROW_PLASMA=ON
: Plasma Shared Memory Object Store-DARROW_PLASMA_JAVA_CLIENT=ON
: Build Java client for Plasma-DARROW_PYTHON=ON
: Arrow Python C++ integration library (required for building pyarrow). This library must be built against the same Python version for which you are building pyarrow. NumPy must also be installed. Enabling this option also enablesARROW_COMPUTE
,ARROW_CSV
,ARROW_DATASET
,ARROW_FILESYSTEM
,ARROW_HDFS
, andARROW_JSON
.-DARROW_S3=ON
: Support for Amazon S3-compatible filesystems-DARROW_WITH_BZ2=ON
: Build support for BZ2 compression-DARROW_WITH_ZLIB=ON
: Build support for zlib (gzip) compression-DARROW_WITH_LZ4=ON
: Build support for lz4 compression-DARROW_WITH_SNAPPY=ON
: Build support for Snappy compression-DARROW_WITH_ZSTD=ON
: Build support for ZSTD compression-DARROW_WITH_BROTLI=ON
: Build support for Brotli compression
Some features of the core Arrow shared library can be switched off for improved build times if they are not required for your application:
-DARROW_IPC=ON
: build the IPC extensions
Optional Targets¶
For development builds, you will often want to enable additional targets in
enable to exercise your changes, using the following cmake
options.
-DARROW_BUILD_BENCHMARKS=ON
: Build executable benchmarks.-DARROW_BUILD_EXAMPLES=ON
: Build examples of using the Arrow C++ API.-DARROW_BUILD_INTEGRATION=ON
: Build additional executables that are used to exercise protocol interoperability between the different Arrow implementations.-DARROW_BUILD_UTILITIES=ON
: Build executable utilities.-DARROW_BUILD_TESTS=ON
: Build executable unit tests.-DARROW_ENABLE_TIMING_TESTS=ON
: If building unit tests, enable those unit tests that rely on wall-clock timing (this flag is disabled on CI because it can make test results flaky).-DARROW_FUZZING=ON
: Build fuzz targets and related executables.
Optional Checks¶
The following special checks are available as well. They instrument the generated code in various ways so as to detect select classes of problems at runtime (for example when executing unit tests).
-DARROW_USE_ASAN=ON
: Enable Address Sanitizer to check for memory leaks, buffer overflows or other kinds of memory management issues.-DARROW_USE_TSAN=ON
: Enable Thread Sanitizer to check for races in multi-threaded code.-DARROW_USE_UBSAN=ON
: Enable Undefined Behavior Sanitizer to check for situations which trigger C++ undefined behavior.
Some of those options are mutually incompatible, so you may have to build several times with different options if you want to exercise all of them.
CMake version requirements¶
While we support CMake 3.2 and higher, some features require a newer version of CMake:
Building the benchmarks requires 3.6 or higher
Building zstd from source requires 3.7 or higher
Building Gandiva JNI bindings requires 3.11 or higher
LLVM and Clang Tools¶
We are currently using LLVM 8 for library builds and for other developer tools
such as code formatting with clang-format
. LLVM can be installed via most
modern package managers (apt, yum, conda, Homebrew, chocolatey).
Build Dependency Management¶
The build system supports a number of third-party dependencies
BOOST
: for cross-platform support
BROTLI
: for data compression
Snappy
: for data compression
gflags
: for command line utilities (formerly Googleflags)
glog
: for logging
Thrift
: Apache Thrift, for data serialization
Protobuf
: Google Protocol Buffers, for data serialization
GTEST
: Googletest, for testing
benchmark
: Google benchmark, for testing
RapidJSON
: for data serialization
ZLIB
: for data compression
BZip2
: for data compression
LZ4
: for data compression
ZSTD
: for data compression
RE2
: for regular expressions
gRPC
: for remote procedure calls
c-ares
: a dependency of gRPC
LLVM
: a dependency of Gandiva
The CMake option ARROW_DEPENDENCY_SOURCE
is a global option that instructs
the build system how to resolve each dependency. There are a few options:
AUTO
: try to find package in the system default locations and build from source if not foundBUNDLED
: Building the dependency automatically from sourceSYSTEM
: Finding the dependency in system paths using CMake’s built-infind_package
function, or usingpkg-config
for packages that do not have this featureBREW
: Use Homebrew default paths as an alternativeSYSTEM
pathCONDA
: Use$CONDA_PREFIX
as alternativeSYSTEM
PATH
The default method is AUTO
unless you are developing within an active conda
environment (detected by presence of the $CONDA_PREFIX
environment
variable), in which case it is CONDA
.
Individual Dependency Resolution¶
While -DARROW_DEPENDENCY_SOURCE=$SOURCE
sets a global default for all
packages, the resolution strategy can be overridden for individual packages by
setting -D$PACKAGE_NAME_SOURCE=..
. For example, to build Protocol Buffers
from source, set
-DProtobuf_SOURCE=BUNDLED
This variable is unfortunately case-sensitive; the name used for each package is listed above, but the most up-to-date listing can be found in cpp/cmake_modules/ThirdpartyToolchain.cmake.
Bundled Dependency Versions¶
When using the BUNDLED
method to build a dependency from source, the
version number from cpp/thirdparty/versions.txt
is used. There is also a
dependency source downloader script (see below), which can be used to set up
offline builds.
When using BUNDLED
for dependency resolution (and if you use either the
jemalloc or mimalloc allocators, which are recommended), statically linking the
Arrow libraries in a third party project is more complex. See below for
instructions about how to configure your build system in this case.
Offline Builds¶
If you do not use the above variables to direct the Arrow build system to preinstalled dependencies, they will be built automatically by the Arrow build system. The source archive for each dependency will be downloaded via the internet, which can cause issues in environments with limited access to the internet.
To enable offline builds, you can download the source artifacts yourself and
use environment variables of the form ARROW_$LIBRARY_URL
to direct the
build system to read from a local file rather than accessing the internet.
To make this easier for you, we have prepared a script
thirdparty/download_dependencies.sh
which will download the correct version
of each dependency to a directory of your choosing. It will print a list of
bash-style environment variable statements at the end to use for your build
script.
# Download tarballs into $HOME/arrow-thirdparty
$ ./thirdparty/download_dependencies.sh $HOME/arrow-thirdparty
You can then invoke CMake to create the build directory and it will use the declared environment variable pointing to downloaded archives instead of downloading them (one for each build dir!).
Statically Linking¶
When -DARROW_BUILD_STATIC=ON
, all build dependencies built as static
libraries by the Arrow build system will be merged together to create a static
library arrow_bundled_dependencies
. In UNIX-like environments (Linux, macOS,
MinGW), this is called libarrow_bundled_dependencies.a
and on Windows with
Visual Studio arrow_bundled_dependencies.lib
. This “dependency bundle”
library is installed in the same place as the other Arrow static libraries.
If you are using CMake, the bundled dependencies will automatically be included
when linking if you use the arrow_static
CMake target. In other build
systems, you may need to explicitly link to the dependency bundle. We created
an example CMake-based build configuration to
show you a working example.
On Linux and macOS, if your application does not link to the pthread
library already, you must include -pthread
in your linker setup. In CMake
this can be accomplished with the Threads
built-in package:
set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
target_link_libraries(my_target PRIVATE Threads::Threads)
Extra debugging help¶
If you use the CMake option -DARROW_EXTRA_ERROR_CONTEXT=ON
it will compile
the libraries with extra debugging information on error checks inside the
RETURN_NOT_OK
macro. In unit tests with ASSERT_OK
, this will yield error
outputs like:
../src/arrow/ipc/ipc-read-write-test.cc:609: Failure
Failed
../src/arrow/ipc/metadata-internal.cc:508 code: TypeToFlatbuffer(fbb, *field.type(), &children, &layout, &type_enum, dictionary_memo, &type_offset)
../src/arrow/ipc/metadata-internal.cc:598 code: FieldToFlatbuffer(fbb, *schema.field(i), dictionary_memo, &offset)
../src/arrow/ipc/metadata-internal.cc:651 code: SchemaToFlatbuffer(fbb, schema, dictionary_memo, &fb_schema)
../src/arrow/ipc/writer.cc:697 code: WriteSchemaMessage(schema_, dictionary_memo_, &schema_fb)
../src/arrow/ipc/writer.cc:730 code: WriteSchema()
../src/arrow/ipc/writer.cc:755 code: schema_writer.Write(&dictionaries_)
../src/arrow/ipc/writer.cc:778 code: CheckStarted()
../src/arrow/ipc/ipc-read-write-test.cc:574 code: writer->WriteRecordBatch(batch)
NotImplemented: Unable to convert type: decimal(19, 4)
Deprecations and API Changes¶
We use the compiler definition ARROW_NO_DEPRECATED_API
to disable APIs that
have been deprecated. It is a good practice to compile third party applications
with this flag to proactively catch and account for API changes.
Modular Build Targets¶
Since there are several major parts of the C++ project, we have provided modular CMake targets for building each library component, group of unit tests and benchmarks, and their dependencies:
make arrow
for Arrow core librariesmake parquet
for Parquet librariesmake gandiva
for Gandiva (LLVM expression compiler) librariesmake plasma
for Plasma libraries, server
Note
If you have selected Ninja as CMake generator, replace make arrow
with
ninja arrow
, and so on.
To build the unit tests or benchmarks, add -tests
or -benchmarks
to the target name. So make arrow-tests
will build the Arrow core unit
tests. Using the -all
target, e.g. parquet-all
, will build everything.
If you wish to only build and install one or more project subcomponents, we
have provided the CMake option ARROW_OPTIONAL_INSTALL
to only install
targets that have been built. For example, if you only wish to build the
Parquet libraries, its tests, and its dependencies, you can run:
cmake .. -DARROW_PARQUET=ON \
-DARROW_OPTIONAL_INSTALL=ON \
-DARROW_BUILD_TESTS=ON
make parquet
make install
If you omit an explicit target when invoking make
, all targets will be
built.
Debugging with Xcode on macOS¶
Xcode is the IDE provided with macOS and can be use to develop and debug Arrow by generating an Xcode project:
cd cpp
mkdir xcode-build
cd xcode-build
cmake .. -G Xcode -DARROW_BUILD_TESTS=ON -DCMAKE_BUILD_TYPE=DEBUG
open arrow.xcodeproj
This will generate a project and open it in the Xcode app. As an alternative,
the command xcodebuild
will perform a command-line build using the
generated project. It is recommended to use the “Automatically Create Schemes”
option when first launching the project. Selecting an auto-generated scheme
will allow you to build and run a unittest with breakpoints enabled.
