Mpfr.h file missing

Hello,

I’m currently running some simulations in R (version 4.0.4) in Yggdrasil, and I encounter some problems when I want to install an R package from CRAN called “SIHR”. I use: module load GCC/10.2.0 OpenMPI/4.0.5 R/4.0.4 to load R. The screenshot of the error is attached.

Any clue how I can fix this issue? Thank you so much in advance for any help! :slight_smile:
