compiler output

in this simple program:

// test.cpp
#include <Eigen/Core>

int main()
  Eigen::MatrixXd Aloc = Eigen::MatrixXd::Zero(3, 3);
// end file

compiled with

g++ -Wall -Wextra test.cpp -I$EIGEN_DIR -o test

one shows some annoying/weird warnings, see attached file.

os: Ubuntu
gcc 4.6.3
eigen 3.1.1
Comment 1 Desire NUENTSA 2012-09-10 10:29:56 UTC
The warning is just about unused variable other which should be used during assertions. Assertions are not called when EIGEN_NO_DEBUG or NDEBUG flags are defined.
