Linux Distribution Packaging

This directory contains packaging files for building native packages on various Linux distributions.

Debian / Ubuntu (.deb)

# Install build dependencies
sudo apt install debhelper cmake ninja-build g++ pkg-config

# Build package from source tarball
dpkg-buildpackage -us -uc -b
# -- or use CPack --
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DSECP256K1_BUILD_SHARED=ON -DSECP256K1_INSTALL=ON
cmake --build build
cd build && cpack -G DEB

Produces:

libufsecp3_<ver>_<arch>.deb -- shared library
libufsecp-dev_<ver>_<arch>.deb -- headers + static lib + cmake/pkgconfig

Fedora / RHEL / CentOS (.rpm)

# Install build dependencies
sudo dnf install cmake ninja-build gcc-c++ rpm-build

# Build RPM from spec
rpmbuild -ba packaging/rpm/libufsecp.spec
# -- or use CPack --
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DSECP256K1_BUILD_SHARED=ON -DSECP256K1_INSTALL=ON
cmake --build build
cd build && cpack -G RPM

Arch Linux (AUR)

# From the packaging/arch/ directory:
cd packaging/arch
makepkg -si

The PKGBUILD downloads the source tarball, builds with CMake+Ninja, runs tests, and installs to /usr.

Generic install (any distro)

cmake -S . -B build -G Ninja \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DSECP256K1_BUILD_SHARED=ON \
    -DSECP256K1_INSTALL=ON \
    -DSECP256K1_INSTALL_PKGCONFIG=ON \
    -DSECP256K1_USE_ASM=ON
cmake --build build -j$(nproc)
ctest --test-dir build --output-on-failure
sudo cmake --install build
sudo ldconfig

After install, applications can find the library via:

pkg-config: pkg-config --cflags --libs ufsecp
CMake: find_package(ufsecp 3 REQUIRED)

Package naming convention

Distro	Runtime	Development
Debian/Ubuntu	`libufsecp3`	`libufsecp-dev`
Fedora/RHEL	`libufsecp`	`libufsecp-devel`
Arch	`libufsecp`	(included in main package)
