Arch Linux User Repository

18.0.0 is not support with old libsecp256k1

The PKGBUILD should adhere to Python package guidelines and some other improvements: - It may not use --skip-dependency-check when building - It should use check() to run tests - What does PYTHONPYCACHEPREFIX="${PWD}/.cache/cpython/" use for? It builds fine wihout it. - Docs can be built with sphinx - (make)depends should be depends=(glibc python python-asn1crypto python-cffi) makedepends=(python-build python-installer python-setuptools python-wheel python-hatchling python-scikit-build-core)

My adjusted PKGBUILD can be used as a reference.

I'd like to co-maintain the package if applicable.

Okay, I've solved it, everyone.

First: this package depends on python-hatchling and python-scikit-build-core, both of which should be added to the makedeps in the PKGBUILD. But also...

Second, as it turns out, this depends on the current version of python-scikit-build-core, which, as of this writing, is 0.10.5; unfortunately, the version in Arch's repo is the out-of-date version 0.9.3, which does not work. (I'm about to go flag it as out of date.) But if you compile your own current version of python-scikit-build-core, which doesn't seem to require any changes to Arch's PKGBUILD beyond the usual updating the version and hashes, and you install that in your chroot, this package compiles just fine.

As an additional data point, removing the skip-dependency-check switch from the build() function and just going with python -m build --wheel --no-isolation breaks with the following error:

ERROR Missing dependencies:

    Aborting...

Which still makes no sense, because cmake is definitely installed in my chroot, and the exact same thing happens if I just use makepkg outside of a chroot. I wonder if this is actually something wrong with python-scikit-build-core, though, which this package explicitly needs.

I have the same problem as @Spixmaster. If I install python-hatchling and python-scikit-build-core, compilation gets only slightly further, failing with the following:

Cmake is definitely installed in my chroot. Bafflingly, searching for the phrase "could not determine cmake version" gets almost no results whatsoever.

Does not build. python-hatchling is a missing dependency.

Steps to Create a VENV in /tmp, Modify pyvenv.cfg, Activate VENV, and Build with Updated PKGBUILD Step 1: Create a Virtual Environment in /tmp

python -m venv /tmp/build_env

Step 2: Modify pyvenv.cfg to Include System Site Packages

sed -i 's/include-system-site-packages = false/include-system-site-packages = true/' /tmp/build_env/pyvenv.cfg

Step 3: Activate the Virtual Environment

source /tmp/build_env/bin/activate

Step 4: Install Necessary Python Packages

pip install --upgrade pip setuptools wheel hatchling scikit-build-core

Step 5: Clone the AUR Package and Update PKGBUILD

Create a new directory for the build and clone the AUR package into it:

mkdir -p /tmp/python-coincurve
cd /tmp/python-coincurve
trizen -G python-coincurve

Update the `PKGBUILD` as shown below and save it:

# Maintainer: Carlos Aznarán <caznaranl@uni.pe>

# Contributor: redfish <redfish@galactica.pw>

prepare() {
  cd ${_base}-${pkgver}
  pip install --upgrade pip
  pip install --upgrade setuptools wheel hatchling scikit-build-core
}

build() {
  cd ${_base}-${pkgver}
  python -m build --wheel --no-isolation
}

package() {
  cd ${_base}-${pkgver}
  PYTHONPYCACHEPREFIX="${PWD}/.cache/cpython/" python -m installer --destdir="${pkgdir}" dist/*.whl
  install -Dm 644 LICENSE-{APACHE,MIT} -t "${pkgdir}/usr/share/licenses/${pkgname}"
}

Step 6: Build and Install the Package

makepkg -si

Full Example Script

Here’s a complete script that includes all the steps:

#!/bin/bash
# Create a virtual environment in /tmp
python -m venv /tmp/build_env

# Modify pyvenv.cfg to include system site packages
sed -i 's/include-system-site-packages = false/include-system-site-packages = true/' /tmp/build_env/pyvenv.cfg

# Activate the virtual environment
source /tmp/build_env/bin/activate

# Install necessary Python packages
pip install --upgrade pip setuptools wheel hatchling scikit-build-core

# Prepare the build directory
mkdir -p /tmp/python-coincurve
cd /tmp/python-coincurve
trizen -G python-coincurve

# Update PKGBUILD as shown above
# Note: You can use an editor to make these changes or use a script to replace the content.

# Build and install the package
makepkg -si

This script ensures that the virtual environment is created and configured correctly, and the package is built and installed using the updated PKGBUILD.

than install with "sudo pacman -U ... "

Installing 'python-scikit-build-core' did the trick. It seems that python-hatchling and python-scikit-build-core are dependencies!?

after installing python-hatchling:

ERROR Backend subprocess exited when trying to invoke build_wheel

installing python-scikit-build doesn't make a difference
