Thanks for the quick fix

could you please verify why this other constructor

  constexpr Rot3( T xx, T xy, T xz, T yx, T yy, T yz, T zx, T zy, T zz) :
    axis{ (Vec){xx,xy,xz,0},
      (Vec){yx,yy,yz,0},
    (Vec){zx,zy,zz,0}
  }{}


constexpr Rot3<float> r1( 0, 1 ,0, 0, 0, 1,  1, 0, 0);

produces
c++ -std=c++11 -Ofast -c ceVec.cc 
ceVec.cc:34:53: error: ‘const Rot3<float>{Rot3<float>::Vec
[3]{Rot3<float>::Vec{0.0f, 1.0e+0f, 0.0f, 0.0f}, Rot3<float>::Vec{0.0f, 0.0f,
1.0e+0f, 0.0f}, Rot3<float>::Vec{1.0e+0f, 0.0f, 0.0f, 0.0f}}}’ is not a
constant expression
 constexpr Rot3<float> r1( 0, 1 ,0, 0, 0, 1,  1, 0, 0);
