Reproduced on my Intel Mac. Result of recent ITK changes perhaps. I will find where the problem begins

[cookpa]

ITK bump in #1651 causes this error on Mac but not Linux

[cookpa]

Compiles fine on Mac with previous ITK (fabc102c520bcbd21ea35e7303e3756c223e10d7), from June 2023. I don't see any changes to the ITK matrix classes that would have caused this.

[cookpa]

OK so the problem looks to be conversion between matrix types in a function added a long time ago by @stnava

ANTs/Tensor/TensorFunctions.h

Line 441 in 62550fc

MatrixType inv = vnl_matrix_inverse<double>(DT);

I don't get why it stopped working now, but the compile error goes away if I explicitly get the inverse matrix with

MatrixType inv = vnl_matrix_inverse<double>(DT).inverse();

It doesn't look like the enclosing function GetMetricTensorCost is used anywhere, so I can't test it further.

@x-avent could you try building #1659? It works on my Intel Mac

[x-avent]

Many thanks for the quick help! It works fine now.
