As discussed here, GCC thinks that macs with Apple silicon have case-sensitive file systems.
Most times you won’t notice this (because your files all have lower-case names which don’t use international characters); however, there’s one case where it has shown up, and that’s if your project (.gpr) file uses configuration pragmas. The case in point said
package Builder is
for Global_Configuration_Pragmas use "gnat.adc";
...
end Builder;
package Compiler is
for Local_Configuration_Pragmas use "gnat_local.adc";
...
end Compiler;
and the effect was that the whole project was recompiled even though nothing had changed.
The workround is to set
export GNAT_FILE_NAME_CASE_SENSITIVE=0
in your login script.
