# Cython extension modules (the "cssm" package), so this build is arch specific.
BuildRequires:  gcc
BuildRequires:  gcc-c++
BuildRequires:  python3-devel
BuildRequires:  pyproject-rpm-macros
# Optional but recommended: GSL provides the validated Ziggurat RNG used by the
# parallel simulators; OpenMP (libgomp, shipped with gcc) enables threading.
BuildRequires:  gsl-devel

%global _description %{expand:
SSM-Simulators (ssms) is a collection of fast simulators and training-data
generators for sequential sampling models (SSMs) used in cognitive science,
neuroscience, and simulation-based ("likelihood-free") Bayesian inference. It
provides Cython implementations of drift-diffusion, race, leaky competing
accumulator, Levy, Ornstein-Uhlenbeck and related models, plus utilities for
generating large parameter-sweep datasets to train likelihood-approximation
networks. It is the simulator backend used by the HSSM toolbox.}

# NOTE: the parallel (nogil/prange) Cython modules require Cython >= 3.2 (as on
# Fedora 44+/rawhide). Older Cython (3.1.x on Fedora 43) rejects them with
# "Assignment of Python object not allowed without gil", so this package is
# built only for Fedora 44 and newer.
