The problem will be solved in time, and in the meantime, we can solve other problems (like in-situ resource utilization, closed-loop habitation, etc.) in parallel.

I don't have an answer for the journey to Mars itself (and I'm also not sure if there's a consensus on how big a danger would such trip pose) - but you'll definitely want to keep the fuel between the passengers and the Sun. It would likely also be wise to pad the whole vehicle with some dense material - but to do that, you'd really want to have some sort of manufacturing capability in cislunar space, to avoid having to lift all that mass upwell.
As for bases on Moon and/or Mars, the best solution is probably to dig in - find a cave or make a tunnel, set up there, and develop underground. Ground is a very good radiation shield.
