¶Step 1 : Setting up Partitions
Now we need a valid partition table on the Hard Drive or SSD that we are using to install Gentoo. We are free to choose any of the utilities available on our live system. I choose cfdisk. You can go with gparted or any other utility you like.
For this tutorial I have the following partitioning scheme.
/dev/sda1 → to be used as /boot
/dev/sda2 → to be used as /swap
/dev/sda3 → to be used as /root
Just create the partitions and you are ready to go, no need to format or worry about mount points at this moment.
¶Step 2 : Formatting
pacman -S dosfstools
# mkfs.vfat /dev/sda1
# mkfs.ext4 /dev/sda3
# mkswap /dev/sda2
¶Step 3 : Mounting

¶Step 5 : Downloading Stage3, arm64, systemd version and Extracting the Tarball into root
You can download the stage3 tarball from here. Choose your architecture, click on stages and download the latest stage3 tarball.
pamman -S wget
# cd /home/alexlai/build/gentoo/src
# wget https://distfiles.gentoo.org/releases/arm64/autobuilds/20230820T223139Z/stage3-arm64-systemd-20230820T223139Z.tar.xz

# tar xvpf stage3-arm64-systemd-20230827T234643Z.tar.xz -C root
[root@hc4Gentoo src]# tar xvpf stage3-arm64-openrc-20230827T234643Z.tar.xz -C root <-- 2023-08-29 try openrc version
¶Step 6 : Chrooting
# pacman -S arch-install-scripts
# arch-chroot root /bin/bash # don't use chroot, might have some problem
# source /etc/profile
# export PS1="(chroot) $PS1"
¶Step 7. /etc/resolv.conf

¶Step 8 : Edit /etc/portage/make.conf
This is one of the most crucial stages of installing Gentoo. Now we must edit /etc/portage/make.conf.
- /etc/portage/make.conf
# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.

¶Step 12. Your First Gentoo System Update
emerge --ask --verbose --update --deep --newuse @world
You can now update your system to match the latest EBUILDS by running this emerge command:
emerge --ask --verbose --update --deep --newuse @world
Total: 47 packages (37 new, 10 reinstalls), Size of downloads: 385675 KiB
* Error: circular dependencies:
(sys-libs/gpm-1.20.7-r5:0/0::gentoo, ebuild scheduled for merge) depends on
(sys-libs/ncurses-6.4_p20230401:0/6::gentoo, ebuild scheduled for merge) (buildtime_slot_op)
(sys-libs/gpm-1.20.7-r5:0/0::gentoo, ebuild scheduled for merge) (buildtime)
It might be possible to break this cycle
by applying the following change:
- sys-libs/ncurses-6.4_p20230401 (Change USE: -gpm)
Note that this change can be reverted, once the package has been installed.
Use emerge @preserved-rebuild to rebuild packages using these libraries
* IMPORTANT: 13 news items need reading for repository 'gentoo'.
* Use eselect news read to view new items.
* After world updates, it is important to remove obsolete packages with
* emerge --depclean. Refer to `man emerge` for more information.s
(chroot) hc4Gentoo / # emerge --depclean
* Always study the list of packages to be cleaned for any obvious
* mistakes. Packages that are part of the world set will always
* be kept. They can be manually added to this set with
* `emerge --noreplace <atom>`. Packages that are listed in
* package.provided (see portage(5)) will be removed by
* depclean, even if they are part of the world set.
*
* As a safety measure, depclean will not remove any packages
* unless *all* required dependencies have been resolved. As a
* consequence of this, it often becomes necessary to run
* `emerge --update --newuse --deep @world` prior to depclean.
!!! You have no world file.
Calculating dependencies... done!
* Dependencies could not be completely resolved due to
* the following required packages not being installed:
*
* dev-libs/libunistring:0/2= pulled in by:
* net-dns/libidn2-2.3.4
*
* dev-libs/libunistring:0/2= pulled in by:
* net-libs/gnutls-3.7.8
*
* Have you forgotten to do a complete update prior to depclean? The
* most comprehensive command for this purpose is as follows:
*
* emerge --update --newuse --deep --with-bdeps=y @world
*
* Note that the --with-bdeps=y option is not required in many
* situations. Refer to the emerge manual page (run `man emerge`)
* for more information about --with-bdeps.
*
* Also, note that it may be necessary to manually uninstall
* packages that no longer exist in the repository, since it may not
* be possible to satisfy their dependencies.
(chroot) hc4Gentoo / # emerge --update --newuse --deep --with-bdeps=y @world
* IMPORTANT: 13 news items need reading for repository 'gentoo'.

Calculating dependencies \
chatGPT,
The error message you've encountered indicates that there is a circular dependency issue involving the sys-libs/gpm and sys-libs/ncurses packages during the package update process. Circular dependencies occur when two or more packages depend on each other, creating a loop that prevents them from being installed or updated successfully.
To fix this issue, you can follow the suggested solution in the error message, which is to temporarily change the USE flag for the sys-libs/ncurses package by removing the "gpm" flag. Here's how you can do it:
Open your terminal.
Run the following command to edit the USE flags for the sys-libs/ncurses package in the Portage configuration:
bash
sudo nano /etc/portage/package.use/ncurses
This will open the Nano text editor for the newly created file.
Add USE Flag: In the opened file, add the following line to remove the "gpm" USE flag for the sys-libs/ncurses package:
plaintext
sys-libs/ncurses -gpm
This line tells Portage not to use the "gpm" feature for the sys-libs/ncurses package.
Save and Close: After adding the line, save the file and close the text editor. In Nano, you can do this by pressing Ctrl + O to write the changes and Ctrl + X to exit.
Run the Update Command: With the new file in place, you can now run the package update command again:
bash
emerge --ask --update --deep --newuse @world
bash
sys-libs/ncurses gpm
Remove the "gpm" USE flag from the line. After making the change, the line should look like this:
bash
sys-libs/ncurses
Save the changes and close the text editor.
Run the following command to update the package dependencies and resolve the circular dependency issue:
css
emerge --ask --update --deep --newuse @world
The package manager should now attempt to install the packages without the circular dependency. After the installation is complete, the circular dependency should be resolved.
If the installation is successful, you can revert the change you made to the USE flags for the sys-libs/ncurses package. Open the /etc/portage/package.use file again and add back the "gpm" USE flag to the line for sys-libs/ncurses.
Remember that while this solution should resolve the circular dependency issue, it's always a good idea to check for any updates or changes in package dependencies before performing updates to ensure a smooth process.

How to solve this error??
I see that your kernel build process has the -Werror flag enabled, which treats all warnings as errors. To resolve the specific error you mentioned earlier without disabling -Werror globally, you can use the following approach:
Edit the Affected Source Code: Open the fs/logfs/readwrite.c file and locate the problematic comparison that triggers the warning. In your error message, it's this line:
c
Copy code
if (block->alias_map)
You can modify this code to address the warning by checking if block->alias_map is non-null before accessing it:
c
Copy code
if (block->alias_map != NULL)
This change explicitly checks if block->alias_map is not NULL before using it, which should satisfy the compiler.
Rebuild: After making this code change, save the file and attempt to rebuild the kernel using the same build command:
Modify the Configuration: If the issue persists, you can try modifying the kernel configuration. It's possible that the 'logfs' filesystem is causing the problem. You can try disabling it in the configuration:
bash
Copy code
make menuconfig --> File System --> Miscellaneous File System -->logfs
It seems you encountered another error related to the -Werror flag in your kernel build, this time in the kernel/extable.c file. To address this, you can apply a similar fix to the one we used for the previous error:
Edit the Affected Source Code: Open the kernel/extable.c file and locate the problematic comparison that triggers the warning. In your error message, it's this line:
c
Copy code
if (main_extable_sort_needed && __stop___ex_table > __start___ex_table) {
You can modify this code to address the warning by using the suggested alternative comparison with array indexing:
c
Copy code
if (main_extable_sort_needed && &__stop___ex_table[0] > &__start___ex_table[0]) {
This change uses array indexing to compare the addresses of __stop___ex_table and __start___ex_table, which should satisfy the compiler.
Rebuild: After making this code change, save the file and attempt to rebuild the kernel using the same build command:
css
Copy code
time make -j4
With the code modification, the build should proceed without treating this particular warning as an error.
Repeat this process for any other similar errors you encounter. Be cautious when making these changes, as they involve modifying the kernel source code. It's important to thoroughly test the resulting kernel to ensure it works as expected, especially if you make code changes to address compiler warnings.
