c++ - Finding the source of a failed static assertion on Eigen -

I'm trying to compile a large code base which IEGEN have few dependencies. By doing this, I got the following error: error C2338: THE_BRACKET_OPERATOR_IS_ONLY_FOR_VECTORS__USE_THE_PARENTHESIS_OPERATOR_INSTEAD that passes is:

  // Eigen \ src \ core \ DenseCoeffsBase.h / ** \ Here returns a reference to the coefficient on the index * this method is only allowed for the expression vector, and matrix expression, LinearAccessBit. * * \ Sa operator [] (index) constant, operator () (index, index), x (), y (), z (), W () * / EIGEN_STRONG_INLINE scalar & amp; Operator [] (index index) {#ifndef EIGEN2_SUPPORT EIGEN_STATIC_ASSERT (Derivative :: IsVectorAtCompileTime, THE_BRACKET_OPERATOR_IS_ONLY_FOR_VECTORS__USE_THE_PARENTHESIS_OPERATOR_INSTEAD) #endif eigen_assert (index> = 0 & index; size ()); Return derivative (). CoEffRef (index); }  

As Eigen dependencies are on all code, how can I get this error trigger line? (Of course, there are [] using a line of access codes to a Eigen matrix, much , the line I'm looking for).

Yes, also faced a similar problem. I have defined a matrix:

Eigen :: MatrixXf minor2x2 (2,2) . The matrix minor2x2 was started like this:

  minor2x2 [0] = 1.0f; Small 2x2 [1] = 1.0 F; Small 2x2 [2] = 1.0 f; Small 2x2 [3] = 1.0 f;  

That was the error started. The solution to the problem is to replace minor2x2 (i) for minor2x2 [i] . I think that Eigen :: Finding Matrix is probably useful
