I have this c code:

extern "C" void main() {
    *(char*)0xb8000 = "Q";
    return;
}

and when I try to compile it whit this command: i386-elf-gcc -ffreestanding -m32 -g -c "kernel.cpp" -o "kernel.o"
I get this error:
i386-elf-gcc: fatal error: cannot execute 'cc1plus': execvp: No such file or directory

foes someone know how to fix it?

I tried reinstalling the cross compiler but nothing did it.
