# Build the source code

Build YugabyteDB from source code on Ubuntu.

Build the source code.

- [AlmaLinux](/stable/contribute/core-database/build-from-src-almalinux/)
- [macOS](/stable/contribute/core-database/build-from-src-macos/)
- [Ubuntu](/stable/contribute/core-database/build-from-src-ubuntu/)

Note

AlmaLinux 8 is the recommended Linux development platform for YugabyteDB.

The following instructions are for Ubuntu 22.04 and 24.04.

## TLDR

The commands below assume the following:

- You have sudo access.
- You are using a bash or zsh shell.
- You are running the commands as the user who will be doing development.

```sh
# Modify to your preference:
shellrc=~/.bashrc

sudo apt update
DEBIAN_FRONTEND=noninteractive sudo apt upgrade -y
packages=(
  autoconf
  build-essential
  ccache
  curl
  file
  gettext
  git
  golang-1.20
  libffi-dev
  locales
  maven
  ninja-build
  npm
  patchelf
  pkg-config
  python3.11
  python3.11-dev
  python3.11-venv
  rsync
)
# Avoid tzdata package configuration prompt.
if [ ! -e /etc/localtime ]; then
  sudo ln -s /usr/share/zoneinfo/Etc/UTC /etc/localtime
fi
DEBIAN_FRONTEND=noninteractive sudo apt install -y "${packages[@]}"
sudo locale-gen en_US.UTF-8
sudo mkdir /opt/yb-build

# If you'd like to use an unprivileged user for development, manually
# run/modify instructions from here onwards (change $USER, make sure shell
# variables are set appropriately when switching users).
sudo chown "$USER" /opt/yb-build
mkdir ~/tools
curl -L "https://github.com/Kitware/CMake/releases/download/v3.31.0/cmake-3.31.0-linux-x86_64.tar.gz" | tar xzC ~/tools
source <(echo 'export PATH="$HOME/tools/cmake-3.31.0-linux-x86_64/bin:$PATH"' \
         | tee -a "$shellrc")
source <(echo 'export PATH="/usr/lib/go-1.20/bin:$PATH"' \
         | tee -a "$shellrc")
source <(echo 'export YB_CCACHE_DIR="$HOME/.cache/yb_ccache"' \
         | tee -a "$shellrc")

git clone https://github.com/yugabyte/yugabyte-db
cd yugabyte-db
./yb_release
```

## Detailed instructions

Update and install basic development packages as follows:

```sh
sudo apt update
sudo apt upgrade -y
packages=(
  autoconf
  build-essential
  curl
  gettext
  git
  locales
  pkg-config
  rsync
)
sudo apt install -y "${packages[@]}"
sudo locale-gen en_US.UTF-8
```

### /opt/yb-build

By default, when running build, third-party libraries are not built, and pre-built libraries are downloaded. The build scripts automatically install these in directories under `/opt/yb-build`. In order for the build script to write under those directories, it needs proper permissions. One way to do that is as follows:

```sh
sudo mkdir /opt/yb-build
sudo chown "$USER" /opt/yb-build
```

Alternatively, specify the build options `--no-download-thirdparty`. Note that those options may require additional, undocumented steps.

### Python 3

Python 3.11 or higher is required.

```sh
sudo apt install -y libffi-dev python3.11 python3.11-dev python3.11-venv
```

### CMake 3

[CMake](https://cmake.org "CMake") 3.31.0 or higher is required.

The CMake version in the package manager is too old, so manually download a release as follows:

```sh
mkdir ~/tools
curl -L "https://github.com/Kitware/CMake/releases/download/v3.31.0/cmake-3.31.0-linux-x86_64.tar.gz" | tar xzC ~/tools
# Also add the following line to your .bashrc or equivalent.
export PATH="$HOME/tools/cmake-3.31.0-linux-x86_64/bin:$PATH"
```

### Java

YugabyteDB core is written in C and C++, but the repository contains Java code needed to run some tests and sample applications. To build the Java part, you need:

- Java Development Kit (JDK) 8 or 11.
- [Apache Maven](https://maven.apache.org/ "Apache Maven") 3.3 or later.

Install the following package to satisfy the preceding requirements:

```sh
sudo apt install -y maven
```

### yugabyted-ui

yugabyted-ui is a UI for [yugabyted](/stable/reference/configuration/yugabyted "yugabyted"). By default, it is not built unless the corresponding build option is specified or a release package is being built. To build it, [npm](https://www.npmjs.com "npm") and [Go](https://go.dev "Go") 1.20 or higher are required.

```sh
sudo apt install -y npm golang-1.20
# Also add the following line to your .bashrc or equivalent.
export PATH="/usr/lib/go-1.20/bin:$PATH"
```

### Ninja (optional)

Install [Ninja](https://ninja-build.org "Ninja") for faster builds as follows:

```sh
sudo apt install -y ninja-build
```

### Ccache (optional)

Install and configure [Ccache](https://ccache.dev "Ccache") for faster builds as follows:

```sh
sudo apt install -y ccache
# Also add the following line to your .bashrc or equivalent.
export YB_CCACHE_DIR="$HOME/.cache/yb_ccache"
```

## Build the code

Assuming [this repository](https://github.com/yugabyte/yugabyte-db "this repository") is checked out in `~/code/yugabyte-db`, do the following:

```sh
cd ~/code/yugabyte-db
./yb_build.sh release
```

The command above will build the release configuration, add the binaries into the `build/release-<compiler>-dynamic-ninja` directory, and create a `build/latest` symlink to that directory.

Note

If you see errors, such as `internal compiler error: Killed`, the system has probably run out of memory. Try again by running the build script with less concurrency, for example, `-j1`.

Note

If you get an error message such as

> ValueError: Found no third-party release archives to download for OS type ubuntu20.04, compiler type matching gcc11, architecture x86\_64, is\_linuxbrew=False. See more details above.

it means that there is no [third-party download](#opt-yb-build "third-party download") available for that build configuration. Check the output that precedes the message for supported configurations.

For more details about building and testing, refer to [Build and test](/stable/contribute/core-database/build-and-test "Build and test").

### Build release package (optional)

Perform the following steps to build a release package:

1. [Satisfy requirements for building yugabyted-ui](#yugabyted-ui "Satisfy requirements for building yugabyted-ui").
2. Install additional packages using the following command:
   
   ```sh
   sudo apt install -y file patchelf
   ```
3. Run the `yb_release` script using the following command:
   
   ```sh
   ./yb_release
   ```
   
   ```output.sh
   ......
   2023-02-17 01:26:37,156 [yb_release.py:299 INFO] Generated a package at '/home/user/code/yugabyte-db/build/yugabyte-2.17.2.0-ede2a2619ea8470064a5a2c0d7fa510dbee3ce81-release-clang15-ubuntu20-x86_64.tar.gz'
   ```

Note

The build may fail with "too many open files". In that case, increase the nofile limit in `/etc/security/limits.conf` as follows:

```sh
echo "* - nofile 1048576" | sudo tee -a /etc/security/limits.conf
```

Start a new shell session, and check the limit increase with `ulimit -n`.
