 |

Hi, fellow gentoo users!
I recently got an Arduino and I was trying to set up my gentoo system following the wiki article... But I'm having some problems installing the toolchain.
I emerged crossdev, but when I run
| Code: | | # USE="-openmp -hardened -sanitize -vtv" crossdev -s4 -S --target avr |
I get
| Code: | * You need to specify an output overlay. Please use --ov-output, or consult
* https://wiki.gentoo.org/wiki/Overlay/Local_overlay for more details.
|
So I made a custom repository (/usr/local/arduino) and I run
| Code: | | # USE="-openmp -hardened -sanitize -vtv" crossdev --ov-output /usr/local/arduino/ -s4 -S --target avr |
Which gives me a new problem:
| Code: | -----------------------------------------------------------------------------------------------------
* crossdev version: 20151026
* Host Portage ARCH: amd64
* Target Portage ARCH: *
* Target System: avr
* Stage: 4 (C/C++ compiler)

* binutils: binutils-[stable]
* gcc: gcc-[stable]
* libc: avr-libc-[stable]
* CROSSDEV_OVERLAY: /usr/local/arduino/
* PORT_LOGDIR: /var/log/portage
* PORTAGE_CONFIGROOT:
* Portage flags:

According to the /var/log/portage/cross-avr-binutils.log there are no ebuild for cross-avr/binutils
| Code: | # cat /var/log/portage/cross-avr-binutils.log
Calculating dependencies ... done!
emerge: there are no ebuilds to satisfy "cross-avr/binutils".
emerge: searching for similar names...
emerge: Maybe you meant any of these: sys-devel/binutils, sys-apps/debianutils, sys-apps/findutils?

But this is what is inside the custom repository
| Code: | # ls -ahl /usr/local/arduino/cross-avr/
total 8.0K
drwxr-xr-x 2 root root 4.0K Mar 29 23:03 .

Can anyone help me understand what I am doing wrong? |

I managed to solve the issue. I just added
| Quote: | | PORTDIR_OVERLAY="${PORTDIR_OVERLAY} /usr/local/arduino/" |
to my /etc/portage/make.conf. |

I just yesterday removed reference to PORTDIR_OVERLAY form make.conf. The current method that portage prefers (although PORTDIR_OVERLAY works) is to stash that information in /etc/portage/repos.conf
That is a directory for me, and contains two files
| Code: | # /etc/portage/repos.conf/gentoo.conf
[DEFAULT]
main-repo = gentoo
[gentoo]
location = /usr/portage
sync-type = rsync
sync-uri = rsync://gentoo/gentoo-portage
auto-sync = yes
[local]
location = /usr/local/portage
auto-sync = no
# /etc/portage/repos.conf/layman.conf
[mozilla]
priority = 50
location = /var/lib/layman/mozilla
layman-type = git
auto-sync = No
[mv]
priority = 50
location = /var/lib/layman/mv
layman-type = git
auto-sync = No |
Your system probably already has a repos.conf file or directory. You should be able to put /usr/local/arduino in there.
Don't copy my [gentoo] entry word for word. The machine "rsync://gentoo" is a machine on my local network. One of the machines on the LAN uses an official Gentoo mirror for the portage tree, then hosts that (as machine "gentoo") for the rest of the LAN.
When I ran crossdev here (to build a 64 bit kernel on a 32 bit system on a 64 bit machine), it put all the portage-related material in /usr/local/portage without any demand that I specify an overlay location. crossdev creates NEW CATEGORIES that are otherwise not in the portage tree, so there is no risk of collision. What I am suggesting is that there is no need to have an overlay (directory) unique to "arduino", your overlay could be /usr/local/portage (I assume you did not have a local overlay before), or /usr/local/crossdev. |
