Describe the problem

When i try to compile a simple Sketch i get this error Error during build: fork/exec /home/hellboy/.arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/avr-g++: no such file or directory and i already downloaded the avr core as you can see here:

~$ arduino-cli core list
ID          Installed Latest Name              
arduino:avr 1.8.6     1.8.6  Arduino AVR Boards

And the verbose says it:

Does /home/hellboy/.arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino7/bin/avr-g++ exists?

Turns out that is a problem related to glibc link, i used a musl distro when i have this bug. Just build and use gcompat solved the problem with the bin linked against glibc. The problem has not been solved in general, maybe given a binarie linked against musl can solve it.
