I tried to compile for Raspberry pi 4 on my amd64 machine as fast a possible.
So I use, also, crossdev without any chroot. I said also, because not all packages compile that way.

But with aarch64-unknown-linux-gnu-emerge -pve system I got:

Code:
aarch64-unknown-linux-gnu-emerge -pve system

These are the packages that would be merged, in order:

Why are the main system packages included ? It is by design ?

costel78,

Code:
aarch64-unknown-linux-gnu-emerge -pve system


-e means --emptytree. You are telling portage to assume that nothing is installed.

Please use @system and @world. Get used to the set namespace.
There are other predefined sets and you can define your own sets.

I forgot to mention, it is the same result with emerge -pve @system.
Is there any way to isolate and recompile only "/usr/aarch64-unknown-linux-gnu/" packages ?

Thank you!

costel78,

Two things ...
Do not use the -e option. That says to pretend that noting is installed and to rebuild everything.
Your output is expected.

To update your arm64 packages use
Code:
emerge-wrapper -t aarch64-unknown-linux-gnu --init
aarch64-unknown-linux-gnu-emerge -uDUav @world --keep-going


Notice your original output says
Code:
to /usr/aarch64-unknown-linux-gnu/
so the output code is going to the right place.

If you want to recompile everything your original command is correct, although @world is safer.
To update, use the command I gave above.

Why do you want to recompile all your arm64 code?

-- edit --
I just noticed in your snippet that everything is there twice.

I suspect you missed the
Code:
emerge-wrapper -t aarch64-unknown-linux-gnu --init
is the shell that you want to run aarch64-unknown-linux-gnu-emerge in

I am very sorry for the delay, been very busy last days.

Yes I did emerge-wrapper -t aarch64-unknown-linux-gnu --init, right after crossdev -t aarch64-unknown-linux-gnu --init-target and crossdev -t aarch64-unknown-linux-gnu.
aarch64-unknown-linux-gnu-emerge and/or emerge-wrapper -t aarch64-unknown-linux-gnu does not help me to recompile all packages in /user/aarch64-unknown-linux-gnu. I want to recompile them because of gcc-9.2.0.
So, until better ideea I came up with:
Code:
#!/bin/bash
mkdir /tmp/costel &>/dev/null
cd /tmp/costel
rm system_list.txt world_list.txt /var/log/portage/elog/summary* &>/dev/null
export exclusion=`cat /home/costel/exclusions.txt`
export excluded_ebuilds='gcc-9\|llvm-8\|clang-8\|openjdk\|firefox\|thunderbird\|libreoffice-6\|chromium'
for f in `aarch64-unknown-linux-gnu-emerge -pe system | grep ebuild | grep '/usr/aarch64-unknown-linux-gnu/' | grep -v $exclusion | grep -v $excluded_ebuilds | gawk '{print $4;}'` ; do echo -n " ="$f ; done > system_list.txt
for f in `aarch64-unknown-linux-gnu-emerge -pe world | grep ebuild | grep '/usr/aarch64-unknown-linux-gnu/' | grep -v $exclusion | grep -v $excluded_ebuilds | gawk '{print $4;}'` ; do echo -n " ="$f ; done > world_list.txt
unset excluded_ebuilds
unset exclusion
MAKEOPTS="-j8 -l10" aarch64-unknown-linux-gnu-emerge -O1 `cat system_list.txt`
MAKEOPTS="-j8 -l10" aarch64-unknown-linux-gnu-emerge -O1 `cat world_list.txt`


/home/costel/exclusions.txt contain the packages which refuze to compile using "plain" cross-compile. Right now there are a little over 120 packages.
On top of everything else, raspberry pi did not arrive yet.

costel78,

As of yesterday, the Pi Foundation 4.19.y kernel supports 4G RAM in 64 bit mode.

You may find my BINHOST useful if you are looking for some shortcuts too.
