Installation

This guide will show how to build, install and update Curio binaries

Debian package installation

Curio packages are available to be installed directly on Ubuntu / Debian systems.

Debain packages are only available for mainnet right now. For any other network like calibration network or devnet, binaries must be built from source.

1. Install prerequisites

   sudo apt install mesa-opencl-icd ocl-icd-opencl-dev gcc git jq pkg-config curl clang build-essential hwloc libhwloc-dev wget libarchive-dev libgmp-dev libconfig++-dev -y && sudo apt upgrade -y

2. Enable Curio package repo

   sudo wget -O /usr/share/keyrings/curiostorage-archive-keyring.gpg https://filecoin-project.github.io/apt/KEY.gpg
   
   echo "deb [signed-by=/usr/share/keyrings/curiostorage-archive-keyring.gpg] https://filecoin-project.github.io/apt stable main" | sudo tee /etc/apt/sources.list.d/curiostorage.list
   
   sudo apt update

3. Install Curio binaries based on your GPU.

   For NVIDIA GPUs:

   sudo apt install curio-cuda

   For OpenCL GPUs:

   sudo apt install curio-opencl

Linux Build from source

You can build the Curio executables from source by following these steps.

Software dependencies

You will need the following software installed to install and run Curio.

System-specific

Building Curio requires some system dependencies, usually provided by your distribution.

Note (Supraseal now builds by default on Linux): Curio’s Linux build chain now always builds extern/supraseal as part of the normal make deps/build flow. This means building Curio on Linux requires Supraseal build dependencies, including:

• CUDA Toolkit 12.x or newer (needs nvcc, even if you won’t run Supraseal at runtime)

• GCC 13 toolchain (gcc-13 / g++-13)

• Python venv tooling (python3-venv) and common build tools (autoconf, automake, libtool, nasm, xxd, etc.)

If you’re troubleshooting whether your machine can run the fast TreeR path used by SnapDeals, run:

curio test supra system-info

Arch:

sudo pacman -Syu opencl-icd-loader gcc git jq pkg-config opencl-headers hwloc libarchive nasm xxd python python-pip python-virtualenv
# For Supraseal builds (SnapDeals fast TreeR / batch sealing toolchain):
sudo pacman -Syu cuda
# GCC 13 may be required depending on your supraseal version; install via your distro/AUR as appropriate.

Ubuntu/Debian:

sudo apt install -y \
  mesa-opencl-icd ocl-icd-opencl-dev \
  gcc-13 g++-13 \
  git jq pkg-config curl clang build-essential hwloc libhwloc-dev wget \
  python3 python3-dev python3-pip python3-venv \
  autoconf automake libtool \
  xxd nasm \
  libarchive-dev libssl-dev uuid-dev libfuse3-dev \
  libnuma-dev libaio-dev libkeyutils-dev libncurses-dev \
  libgmp-dev libconfig++-dev \
  && sudo apt upgrade -y

# CUDA Toolkit (Supraseal build requirement; needs nvcc)
# Install via NVIDIA’s CUDA repository packages for your distro, or use `cuda-toolkit` packages if available.

Fedora:

sudo dnf -y install gcc make git jq pkgconfig mesa-libOpenCL mesa-libOpenCL-devel opencl-headers ocl-icd ocl-icd-devel clang llvm wget hwloc hwloc-devel libarchive-devel

OpenSUSE:

sudo zypper in gcc git jq make libOpenCL1 opencl-headers ocl-icd-devel clang llvm hwloc libarchive-devel && sudo ln -s /usr/lib64/libOpenCL.so.1 /usr/lib64/libOpenCL.so

Amazon Linux 2:

sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm; sudo yum install -y git gcc jq pkgconfig clang llvm mesa-libGL-devel opencl-headers ocl-icd ocl-icd-devel hwloc-devel libarchive-devel

Rustup

Curio needs rustup. The easiest way to install it is:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Go

To build Curio, you need a working installation of Go: It needs to be at-least the version specified here.

Example of an OLD version's CLI download:

wget -c https://golang.org/dl/go1.23.6.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local

You’ll need to add /usr/local/go/bin to your path. For most Linux distributions you can run something like:

echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc && source ~/.bashrc

See the official Golang installation instructions if you get stuck.

System Configuration

Before you proceed with the installation, you should increase the UDP buffer. You can do this by running the following commands:

sudo sysctl -w net.core.rmem_max=2097152
sudo sysctl -w net.core.rmem_default=2097152

To persist the UDP buffer size across the reboot, update the /etc/sysctl.conf file.

echo 'net.core.rmem_max=2097152' | sudo tee -a /etc/sysctl.conf
echo 'net.core.rmem_default=2097152' | sudo tee -a /etc/sysctl.conf

Build and install Curio

Once all the dependencies are installed, you can build and install Curio.

1. Clone the repository:\

   git clone https://github.com/filecoin-project/curio.git
   cd curio/

2. Switch to the latest stable release branch:\

   git checkout <release version>

3. Enable the use of SHA extensions by adding these two environment variables:

   export RUSTFLAGS="-C target-cpu=native -g"
   export FFI_BUILD_FROM_SOURCE=1
   
   echo 'export RUSTFLAGS="-C target-cpu=native -g"' >> ~/.bashrc
   echo 'export FFI_BUILD_FROM_SOURCE=1' >> ~/.bashrc
   source ~/.bashrc

4. If you are using a Nvidia GPU, please set the below environment variables.\

   export FFI_USE_CUDA=1
   export FFI_USE_CUDA_SUPRASEAL=1
   
   echo 'export FFI_USE_CUDA=1' >> ~/.bashrc
   echo 'export FFI_USE_CUDA_SUPRASEAL=1' >> ~/.bashrc
   source ~/.bashrc

5. Curio is compiled to operate on a single network. Choose the network you want to join, then run the corresponding command to build the Curio node:\

   # For Mainnet:
   make clean build
   
   # For Calibration Testnet:
   make clean calibnet

6. Install Curio. This will put curio in /usr/local/bin. curio will use the $HOME/.curio folder by default.

   sudo make install

7. Run curio --version

curio version 1.24.5+mainnet+git_214226e7_2025-02-19T17:02:54+04:00
# or
curio version 1.24.5+calibnet+git_214226e7_2025-02-19T17:02:54+04:00

You should now have Curio installed. You can now finish setting up the Curio node.

MacOS Build from source

You can build the Curio executables from source by following these steps.

Software dependencies

You must have XCode and Homebrew installed to build Curio from source.

XCode Command Line Tools

Curio requires that X-Code CLI tools be installed before building the Curio binaries.

Check if you already have the XCode Command Line Tools installed via the CLI, run:

xcode-select -p

This should output something like:

/Library/Developer/CommandLineTools

If this command returns a path, then you have Xcode already installed! You can move on to installing dependencies with Homebrew. If the above command doesn’t return a path, install Xcode:

xcode-select --install

Next up is installing Curio’s dependencies using Homebrew.

Homebrew

We recommend that macOS users use Homebrew to install each of the necessary packages.

Use the command brew install to install the following packages:

brew install jq pkg-config hwloc coreutils
brew install [email protected]

Next up is cloning the Lotus repository and building the executables.

Rust

Rustup is an installer for the systems programming language Rust. Run the installer and follow the onscreen prompts. The default installation option should be chosen unless you are familiar with customisation:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Build and install Curio

The installation instructions are different depending on which CPU is in your Mac:

• ARM-based CPUs (M1, M2, M3)

• Intel CPUs

Arm based CPUs

1. Clone the repository:

   git clone https://github.com/filecoin-project/curio.git
   cd curio/

2. Switch to the latest stable release branch:

   git checkout <release version>

3. Create the necessary environment variables to allow Curio to run on Arm architecture:

   export LIBRARY_PATH=/opt/homebrew/lib
   export FFI_BUILD_FROM_SOURCE=1
   export PATH="$(brew --prefix coreutils)/libexec/gnubin:/usr/local/bin:$PATH"

4. Build the curio binary:

   make clean curio

5. Run the final make command to move this curio executable to /usr/local/bin. This allows you to run curio from any directory.

   sudo make install

6. Run curio --version

   curio version 1.24.5+mainnet+git_214226e7_2025-02-19T17:02:54+04:00
