Error when compiling R packages : Eigen/Core : new: no file or directory

Question

This is my first question on stack ! Hope I follow correctly the guidelines...

Device

• Thinkpad series
• Manjaro KDE (kernel 5.13)
• Fresh R install (4.2)
• Fresh Rstudio install
• Several packages installed yesterday evening, following approximately this roadmap (it includes rstan, which has specific installation requirements)

Problem

So, installing several packages of R (4.2) in rstudio, I encountered the same error with several dependencies (but not all). Eg here for mvtnorm or nleqslv (both while installing brms). (see error at the bottom of this message).

It seems that the problem concerns the line 82 of the Eigen/Core header, located in Rcppeigen directory. The #include <new> isn't correctly understood by the compiler.

What I've already done

• Trying to reinstall Rcppeigen (but it didn't work)
• Online queries around this include new problem : I found a little amount of similar errors, but only with quite surprising devices (like an Arduino here)...

As I'm on a Thinkpad laptop, this shouldn't appear. Should I use another compiler ?

Thanks for your help !

Answer 1

Well, finally I solved it myself after some hours stacking with it.

So. In order to install Rstan, I followed these instructions. In order to revert it, I deleted the content of the file .R/Makevars and I restarted R. I don't know why it was creating this error. But the issue seems now to be solved.
