Hello,

I have a RaspberryPi with gentoo, I use crossdev to update it. I have
NFS server and client on both the Host and the Target so that I can mount:

on the Target, the Host's
/usr/aarch64-unknown-linux-gnu/var/cache/binpkgs /usr/aarch64-unknown-linux-gnu/var/db/repos

and on the Host, the Target's
/var/db/pkg

I copy the Target's world file manually from Target to Host's /usr/aarch64-unknown-linux-gnu/var/lib/portage/

All works fine, I cross-build on Host binary packages and then 'emerge --usepkg' on the Target.

Well, almost all... On the Target I have apache, on the Host not because
I don't need it. Sometimes the update wants to install apache also on
the Host.

For example, today I have:

# emerge-aarch64-unknown-linux-gnu -uDvNa @world

Note the lines without 'to /usr/aarch64-unknown-linux-gnu/", these

Any ideas why?

Hi Ralf

One possible explanation is that "www-servers/apache" could be a build dependency of some other package. However I don't see in the list of
updates any package with this kind of dependency on
"www-servers/apache".

The only one that seems to depend on it is "app-eselect/eselect-php",
but it'd be installed on the host.

Do you install "dev-lang/php" on the target or the host or both ?

php is not on the Host:
# eix -I php apache
No matches found

It is on the Target, as a dependency of www-apps/pihole-admin-lte (tatsh-overlay) while apache is a dependency of php with USE=apache2.
All as expected.

Looking at the pihole-admin-lte ebuild I find this:

BDEPEND="app-misc/jq app-portage/portage-utils"
RDEPEND="app-admin/sudo
dev-lang/php[fileinfo,filter,gd,intl,session,sqlite,tokenizer]
net-dns/pihole
virtual/httpd-php"

Humm, interesting, jq is another package that crossdev wants to install
on the Host. BDEPEND are build-time dependencies and it is correctly cross-built on Host but for some reason crossdev wants to build it also
for the Host.

Could it be an issue with the pihole-admin-lte ebuild rather than
apache's? I'd need to understand ebuilds, easier said than done...
