Hi Roberto, thanks for the quick response.
I ran make after cleaning it up and getting your commit. This time the
compilation goes further until this happens:
make[2]: Leaving directory '/home/blmayer/git/distro/scc/src'
make[1]: Leaving directory '/home/blmayer/git/distro/scc'
make[1]: Entering directory '/home/blmayer/git/distro/scc'
make[1]: *** No rule to make target 'aarch64'. Stop.
make[1]: Leaving directory '/home/blmayer/git/distro/scc'
make: *** [Makefile:18: all] Error 2
This was the Makefile in the root folder not having the aarch64
target, so I added it to the scripts/arm64.mk file which gets included
in the Makefile. Like this:
diff --git a/scripts/arm64.mk b/scripts/arm64.mk
index 949eb49b..f6ae8961 100644
--- a/scripts/arm64.mk

Not sure if this is the right choice. So running make again takes it
further but there comes a new error:

This one I tried to circumvent without success. Here's what I've done:
- Removed the int type from file
include/bits/linux/arm64/arch/stdint.h:103. Then run make again, this
error disappeared.
- Removed the arch/ from file include/inttypes.h:5, not sure if this
is specific to my system. Then run make again and a much weirder
error:

Inspecting the folder containing those assembly files I see:
[blmayer_at_alarm scc]$ ls src/libc/arch/arm64/linux/
Makefile _cerrno.s _close.s _execve.s _exit.s _getpid.s
_kill.s _lseek.s _openat.s _read.s deps.mk syscall.lst
__sigaction.s _close.7l _execve.7l _exit.7l _getpid.7l _kill.7l
_lseek.7l _openat.7l _read.7l crt.s gensys.sh
Note that only sigaction.s has 2 "_" before it. So I removed it, by
editing the file src/libc/arch/arm64/linux/syscall.lst. This may be
some Makefile with a typo. I'm not sure if that's correct, but
compilation ran further:

After taking a look at:

edited that file and changed the following:

That's where I stopped. Hope it helps. I don't know why the storage
size isn't known. Couldn't work this further.
Thanks.
Brian
