Re: [eigen] Conflict between coeffRef and CppAD

[Hilario Tomé <tome.hilario@xxxxxxxxx>]

Thank you Christoph, does this mean that the issue is fixed in version 3-3-beta1 or that it will be fixed in the near future?

Dear all,

I am reviving this topic since I didn't manage to solve it, can you give me
any suggestions to fix it? Gael already suggested a sparse matrix plugin
that solves the problem for the setFromTriplets method, can something
similar be done for coeffRef?

This problem still exists with Eigen 3.2.8 and gcc 4.8.4.

We'll probably won't fix this for the 3.2 branch (and if we do, you'd need to wait for the next release). I guess, the easiest solution is to upgrade to 3.3-beta1.

Christoph

Best,

yes, let's go with a value_type alias to Scalar. Even though that's a bit
ugly, this will simplify everybody's life!

I would appreciate if someone could also explain the reason of the
problem.

 From looking at the error message, it appears that CppAD adds a
value_type typedef to EigenBase, thus making our SFINAE-mechanism fail.

I'm tending to agree to simply add a value_type typedef ourselves (Bug
360), and drop that SFINAE construct.
