 Posted: Sun Nov 20, 2016 2:22 pm Post subject: Can't get crossdev to set up for Raspberry Pi 3 |
 |
|
I'm attempting to set up cross compilation for my Raspberry Pi 3 running at 32-bit. I have a Gentoo VM which I'm working with to be the cross-compiler host.
I've been following the instructions here:
https://wiki.gentoo.org/wiki/Raspberry_Pi/Cross_building#crossdev
Unfortunately I got stuck at the last part.
The first error I got was that crossdev now seems to need an argument for --ov-output, so I created a local overlay using the instructions here https://wiki.gentoo.org/wiki/Overlay/Local_overlay , and then pointed --ov-output to that directory, so now my command is:
| Code: | | crossdev -S -v -t armv7a-hardfloat-linux-gnueabi --ov-output /usr/local/portage-crossdev/ |
This results in the following output:
| Code: |
--------------------------------------------------------------------------------------------

* Target Portage ARCH: arm
* Target System: armv7a-hardfloat-linux-gnueabi

These are the packages that would be merged, in order:

I'm not sure what I'm doing wrong here. I found another thread that suggested that the name of the target might be mispelled, but I made sure that it's correct. Any other ideas?

9a3eedi,
The --ov-output tells crossdev which overlay to put the cross ebuilds in.
| Code: | | --ov-output /usr/local/portage-crossdev/ |
| Code: | $ eix cross-armv7a-hardfloat-linux-gnueabi/binutils
[I] cross-armv7a-hardfloat-linux-gnueabi/binutils [1]
Available versions:
(2.21.1) 2.21.1-r1
(2.22) 2.22-r1
(2.23.2) 2.23.2

(2.25) (~)2.25{tbz2} (~)2.25-r1{tbz2}
(2.25.1) 2.25.1-r1{tbz2}

Homepage: https://sourceware.org/binutils/
Description: Tools necessary to build programs
[1] "gentoo_static" /usr/local/gentoo-static
|
in my case /usr/local/gentoo-static
Portage won't look there unless you tell it about the overlay.
I have | make.conf: | | PORTDIR_OVERLAY="/usr/local/gentoo-static /usr/local/portage" |
That's probably depreciated in favour of a repros.conf entry now.

Fixed long line

Thanks.
It seems I have missed the final instruction in the Local Overlay webpage, which is to create a file called /etc/portage/repos.conf/crossdev.conf with the following
| Code: |
[crossdev]
location = /usr/local/portage-crossdev
priority = 10
masters = gentoo
auto-sync = no
|
Your post made me realize this, thanks. I also had to add ~amd64 to my portage settings to get it to build.
Perhaps I should edit the wiki to account for these changes. |
