Hi All, |
| 2 |
|
| 3 |
I am dipping my toe into cross-compile territory, in order to build i686 |
| 4 |
binaries for a 32bit box, which is too old to do its own emerges. I am using |
| 5 |
an amd64 box which is significantly faster to do all the heavy lifting and |
| 6 |
started applying this page: |
| 7 |
|
| 8 |
https://wiki.gentoo.org/wiki/Embedded_Handbook/General/Creating_a_cross-compiler |
| 9 |
|
| 10 |
which I followed up with: |
| 11 |
|
| 12 |
https://wiki.gentoo.org/wiki/Cross_build_environment |
| 13 |
|
| 14 |
and attempted to build @system: |
| 15 |
========================= |
| 16 |
# i686-pc-linux-gnu-emerge -uva @system |
| 17 |
|
| 18 |
* IMPORTANT: 3 news items need reading for repository 'gentoo'. |

These are the packages that would be merged, in order: |
| 23 |
|
| 24 |
Calculating dependencies... done! |
| 25 |
[ebuild N ] sys-apps/busybox-1.24.2::gentoo to /usr/i686-pc-linux-gnu/ |
| 26 |
USE="make-symlinks static -debug -ipv6 -livecd -math -mdev -pam -savedconfig (- |
| 27 |
selinux) -sep-usr -syslog -systemd" 0 KiB |
| 28 |
|

Total: 1 package (1 new), Size of downloads: 0 KiB |

|
| 31 |
Would you like to merge these packages? [Yes/No] y |
| 32 |
* ARCH is not set... Are you missing the '/usr/i686-pc-linux- |
| 33 |
* gnu/etc/portage/make.profile' symlink? Is the symlink correct? Is your |
| 34 |
* portage tree complete? |
| 35 |
=============== |

|
| 37 |
As far as I can tell the link is there: |
| 38 |
|
| 39 |
# ls -la /usr/i686-pc-linux-gnu/etc/portage/ |
| 40 |
total 8 |
| 41 |
drwxr-xr-x 1 root root 56 Jul 31 19:32 . |
| 42 |
drwxr-xr-x 1 root root 20 Jul 31 18:32 .. |
| 43 |
-rw-r--r-- 1 root root 1019 Jul 31 19:32 make.conf |
| 44 |
lrwxrwxrwx 1 root root 30 Jul 31 17:48 make.profile -> |
| 45 |
/usr/portage/profiles/embedded |
| 46 |
drwxr-xr-x 1 root root 32 Jul 31 18:16 profile |
| 47 |
|
| 48 |
and it was created when I ran 'crossdev --stable -v -t i686-pc-linux-gnu'. |
| 49 |
|

My make.conf looks like this: |

What am I missing? How would/do you go about achieving the same objective? |
