I think this is a mistake

SO: Debian 10 buster
R version: 3.6.3

When I try to install a package it appears like this.
Command used: install.packages ("learnr")

** libs
g++ -std=gnu++11 -I"/usr/share/R/include" -DNDEBUG -I.    -UDEBUG -DNDEBUG -DU_HAVE_ELF_H   -fpic -fpic  -g -O2 -fdebug-prefix-map=/home/jranke/git/r-backports/buster/r-base-3.6.3=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 -g  -c stri_brkiter.cpp -o stri_brkiter.o

You are not showing any error message so far, can you post the complete error message you get? Or better explain what your problem is?

[danielfersi]

When I try to install a package, only these messages appear. Some say it is the gcc compiler.
I use gcc 4.8 and in version 4.9+ this message does not appear, so I am in doubt if it is an error or not.

Those are just normal installation messages so unless you get an error message after that, I would say there is no problem.
