 |
|
Trying to setup my main desktop amd64 as a binhost for my pi. Apparently when trying to build the stage1 it cant find libcc1 on lib64. However after some research I found out it was being placed into regular /lib. I don't really know how to proceed since it's looking for it in the wrong place? Apparently this was a bug that got fixed a couple years ago and none issues have been filed ever since.

/libcc1*': No such file or directory |

acertig,
Run crossdev to get the cross toolchain. | Code: | | crossdev -t aarch64-unknown-linux-gnu |
This will get you an 'empty' target root filesystem /usr/aarch64-unknown-linux-gnu/ on the build box.
Fix the profile symlink in /usr/aarch64-unknown-linux-gnu/etc/portage to point to the profile of you choosing for the Pi. The default embedded profile is not useful.
Set the USE flags for the Pi in /usr/aarch64-unknown-linux-gnu/etc/portage/make.conf
Execute | Code: | | emerge-wrapper --init -t aarch64-unknown-linux-gnu |
| Code: | | aarch64-unknown-linux-gnu-emerge -av @system --keep-going |
will now try to cross compile the system set and install it into /usr/aarch64-unknown-linux-gnu/
It will also save binary packages to suit the Pi. A few packages are expected to fail.
| Code: | # aarch64-unknown-linux-gnu-emerge -pv @system
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild N ] sys-apps/gentoo-functions-0.17::gentoo to /usr/aarch64-unknown-linux-gnu/ 0 KiB
[ebuild N ] sys-libs/timezone-data-2022g::gentoo to /usr/aarch64-unknown-linux-gnu/ USE="-leaps-timezone -nls -zic-slim" 0 KiB
[ebuild N ] virtual/libiconv-0-r2::gentoo to /usr/aarch64-unknown-linux-gnu/ 0 KiB

Notice the install location.
If you want a 32 bit Pi install, change the tuple to suit.
I have a 64 bit binhost for Pi3 and Pi4.
As of last night, its also available over https but there is no auto redirect.
Its also possible to populate the target root using the target stage3.
If you do that, preserve the make.conf left by crossdev and the target stage3 will install a target make.conf, which is not what you want for cross compiling.

| lots of packages did refuse to compile but they do not amount to even half of the @system set |
