Hello everyone!
I'm a beginner in ROS and I was working around this tutorial: Coding a real time Cartesian controller with Eigen
However, the following declaration:
" typedef Eigen::Transform3d CartPose;"
leads to the error:
"Transform3d’ in namespace ‘Eigen’ does not name a type".
Any suggestion is very much welcome!

I just solved this problem. As indicated in this page, Transform3f should be replace with Affine3f. Likewise, I should use Affine3d rather than Transform3d.
The detailed definition could be found here
Thank you for all the replies!
Without any additional information:
If you are following those tutorials with ROS Fuerte, it could be that you're seeing an issue with Eigen 2 vs 3. It is a bit strange though that only the Eigen::Transform3d typedef is giving you problems.
If you think this is your issue, you could take a look at Porting from Eigen2 to Eigen3, at the Eigen website.

Could you post some more context? Which version of ROS? Surrounding lines of the error? These types of errors mostly occur if you are missing '#include' statements, or don't have the (proper versions of) headers installed.
