# gcc 4.6.1's plugin/include/double-int.h includes "gmp.h", but on Fedora,
# gmp-devel isn't yet listed in the requirements of gcc-plugin-devel
# For now, explicitly require it:

# Filed as https://bugzilla.redhat.com/show_bug.cgi?id=725569


# Various python runtimes to build the plugin against:
BuildRequires:  python-devel
BuildRequires:  python-debug
BuildRequires:  python3-devel
BuildRequires:  python3-debug

# "six" is used at buildtime:
BuildRequires:  python-six
BuildRequires:  python3-six

# sphinx is used for building documentation:
BuildRequires:  python-sphinx

# pygments is used when running the selftests:
BuildRequires: python-pygments
