That post does not show the output of make as it invoked gcc . That post assumes use of genkernel. It's not clear from your most recent posts if you built the kernel by hand or if you let genkernel do it.
I built the kernel using genkernel all

You might be able to derive the answer from the ...

For a manual build of the kernel, make V=1 makefile_target will show the full compiler invocations, including compiler options used. I don't know how to do it when Genkernel is used to build the kernel, though.
I would suggest MAKEOPTS="V=1" in /etc/genkernel.conf . Not tested though.

Added ...

Matching size is suspicious, but not definitive. What command line did make use to run gcc on the kernel source? What did you do that you expected to influence the kernel's build?

See post #2 in this thread, I think that post answer your questions.

To get to the bottom with the similarities of ...

May i quote from the file /etc/genkernel.conf: # Genkernel uses an independent configuration for MAKEOPTS, and does not source
# /etc/portage/make.conf . You can override the default setting by uncommenting
# and tweaking the following line. Default setting is set up by

Thanks for the heads-up!

Thanks, tried that but it still didn't work as the use flag was masked. Had to the unmask the use flag by: and setting custom-cflags in make.conf:

found the solution elsewhere:
nano /etc/genkernel.conf

And add the line:

KERNEL_CFLAGS="-O2 -march=native -pipe -fomit-frame-pointer"

Then go to linux source folder and issue the command:

genkernel all


Verify CFLAGS using

nano /var/log/genkernel.log


look for the entry * KERNEL ...

Hello Gentoo Community,
when using genkernel, is the kernel compiled using the custom cflags in the /etc/portage/make.conf when the is executed?

Hello,
I'm using the profile is there a way of making glibc compile using custom-cflags?

I solved the mystery with the black screen upon boot. All that was needed was to insert `hdmi_hotplug=1` in config.txt and the screen wouldn't go blank. No need to reinstall Gentoo, I hope.
However, I managed to boot once without first needing to go through systemd `emergency mode`, but that was ...

EliasJonsson,
I know that config.txt. I wrote it. :)

I am glad you did! It has been working terrifically well indeed!

@neddy,
@Eliasjosson,
I don't use systemd, so I am just using Internet search for an answer . May be you can try systemctl --failed in the emergency shell to gather more information on what happen

I wish that I could. After an update I now lost visuals. There is no terminal to be seen. Display ...

EliasJonsson,

I don't use an initrd, so I don't have an emergency shell.

You should have got an error about something failed, dropping you to a shell.
What was the error?

To save me asking later. please post the output of ls -l /boot and the content of both cmdline.txt and config.txt

Here ...

I thought that I would try booting the broken system again, and lo and behold, the system started without me intervening!
The joy was unfortunately short, because the error reappeared after the next boot, I landed in an emergency shell once again.

Everything seems to be well until 5.6s into the ...

Thank you, NeddySeagoon, for your questions and your attention. However, I'm afraid its tool late for that. I switched to Ubuntu Server. Hopefully the slower and less optimized distribution will not come with nasty surprises as Gentoo have given me lately. Good bye Gentoo, it truly was a blast!

I have two Raspberry Pi 4 running Gentoo using SSDs connected to the Pi's USB ports. Both boxes are updated. Today I tried rebooting one of them. The box dropped to emergency shell.
Tried rebooting the other one. It dropped to an emergency shell. Something tells me Gentoo currently have some ...

I run Gentoo on a Raspberry Pi 4 4GB. That box hosts a website running Nginx and PHP FPM.
About every 50 page load or so, Nginx tells the user '502 bad gateway', so I looked in the /var/log/php-fpm.log and found this:

As mentioned above, use rust-bin then instead if you cannot compile rust.

Will do. Thanks for pointing that out!

I own a Raspberry Pi 4, 4GB RAM. 4 GB RAM isn't enough in order to compile the Rust package. Although, It is possible to just run
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
and have Rust installed.

Is it possible to somehow tell Portage that the rust package already is ...

Speed is something every Gentoo user values, I can imagine. Why isn't Portage written in a natively compiled language like Rust?
Has there been any talk about rewriting Portage lately?

well yes. Saving config files throughout the system. Anyways, I removed the /.git directory and syncthing compiled successfully. Thank you for pointing me in the right direction!

The following lines are now commented out in make.conf:
#FEATURES="ccache"
#CCACHE_DIR="/var/cache/ccache"

and `ran emerge --unmerge ccache` just to be sure it was disabled.


now emerge --info outputs:
