Requires:       %{name}%{?_isa} = %{version}-%{release}

%description devel
This package contains the header files and the shared library symlinks 
needed to develop programs that use the Cuba library.

%prep
%setup -q -n Cuba-%{version}

%build
# 1. Add -fPIC so object files can be used in a shared library
export CFLAGS="%{optflags} -std=gnu11 -fPIC"
%configure

# 2. Build the static library. 
# Disable parallel flags to avoid race conditions in Cuba's Makefile.
%{__make}

# 3. Handle Shared Library Creation
