Cross emerge use flag questions.aarch64 to set abi_x86_32?

[tenspd1370]

Hi all,

I have been able to sucessfully build an aarch64 cross compiler using cross dev and setup a qemu-chroot. I was using the /usr/aarch64-unknown-linux-gnu directory as a sysroot. I noticed that when I try a cross emerge (aarch64-unknown-linux-gnu-emerge -uavDN @world) it wants to use my /etc/portage/package.use directory and tries to add abi_x86_32, which probably shouldn't happen on arm64. Do I need to put all my use flags from /usr/aarch64-unknown-linux-gnu/etc/portage/package.use into /etc/portage/package.use/cross-aarch64..., can that file be further turned into a directory I can copy /usr/aarch64-unknown-linux-gnu/etc/portage/package.use/ into, should I stick with chrooting and qemu (which seems slower, but a lot cleaner), or is there something I have missed?

Thanks!

tenspd1370,

Code: Select all

aarch64-unknown-linux-gnu-emerge -uavDN @world 

should use the settings in /usr/aarch64-unknown-linux-gnu/etc/portage

Did you remember to run emerge-wrapper --init ?

[tenspd1370]

I think I did. I'll try again when I get a chance. With holidays, kids at home, etc., I haven't had a lot of time to play.

Much appreciated!

[tenspd1370]

Neddy,

Sorry for the long delay - finally getting a chance to do this -

Code: Select all

emerge-wrapper -t aarch64-unknown-linux-gnu --init

After running this program with the --init option as root
you can call it directly like emerge-wrapper --target CHOST <emerge options>
or using the emerge-CHOST wrappers

so that looks good....

Would you like to add these changes to your config files? [Yes/No] no

It wants to add abi_x86_32.

It is odd, I am sure I am doing something wrong, but I haven't got a clue what it is.

If you get the chance, thanks for taking a look!

Where is ARCH defined ?
My make.conf contains the line ARCH=arm64

What about your profile setting in /usr/aarch64-unknown-linux-gnu/etc/portage/ ?

make.profile points to the basic arm64 profile

Code: Select all

make.profile -> ../../usr/portage/profiles/default/linux/arm64/17.0

I tried adding ARCH=arm64, with no luck before I noticed the following:
# Note: profile variables are set/overridden in profile/ files:
# etc/portage/profile/use.force (overrides kernel_* USE variables)
# etc/portage/profile/make.defaults (overrides ARCH, KERNEL, ELIBC variables)

They are set there:

Code: Select all

ARCH="arm64"
KERNEL="-linux linux"
ELIBC="glibc"

Not sure what the -linux linux setting does.

Thanks again for helping me figure this out!

[tenspd1370]

One thought on this - could it just be that it wants to build 32 and 64 bit libraries? I don't think I have done anything specifically that would make this non-multilib (although I probably should), and I suppose arm could have 64 bit as well as 32 bit libraries? I just took the x86 in the use flag literally. Or is that stretching it?

**** Never mind - while possible, being able to run 32bit arm binaries on 64bit is not the default behavior. *****

Back to square one.... Have I maybe found a crossdev bug?

Interestingly though - arch64-unknown-linux-gnu-emerge -uav @system --keep-going does not want to add abi_x86_32....

I understand that -D forces a look at entire dependency tree - I wonder how that is affecting this? Any other thoughts?

Vexing....

Thanks again for your time.
