I'm getting compilation problems when trying to use SPQR. I'm having difficulty making a minimal reproduction, but the errors are of the form:
/usr/local/include/eigen3/Eigen/src/SPQRSupport/SuiteSparseQRSupport.h:142:12: error: no matching function for call to ‘Eigen::Map<Eigen::Matrix<double, -0x00000000000000001, 1>, 0, Eigen::Stride<0, 0> >::Map()’
I believe the problem may be in _solve in SuiteSparseQRSupport.h. If I change:
typename Dest::PlainObject y;
It compiles and (seems) to work.
