%description
qt provides Ruby bindings for Qt 6 with an AST-generated bridge over a native
extension (qt_ruby_bridge.so).

This package ships prebuilt binaries for the target Fedora buildroot.

%prep
%autosetup -n %{name}-%{version}

%build
# Guard against source/spec version drift (SRPM is built from git HEAD).
gem_version=$(ruby -e "spec = Gem::Specification.load('qt.gemspec'); puts spec.version")
if [ "$gem_version" != "%{version}" ]; then
  echo "Version mismatch: qt.gemspec=$gem_version, spec=%{version}" >&2
  exit 1
