Yes. Code you write can be under any license you like. When someone uses the combination then they have to comply with all the licenses (so implicitly there's the constraint that the license you pick must be compatible with the license of the other parts). > 2) If someone uses hmatrix but no GSL functions (hence there are no > GSL functions in the linked binary) can they get away with not > complying with the GSL requirement? Not sure. In practice I don't think you can achieve that with our toolchain.
