How to setup an Arduino Uno board in Gentoo

[andrewwalker27]

Still can't get it working! I've started from scratch and done the following

Installed crossdev-20120531
emerge sys-devel/crossdev
and
crossdev -t avr
------------------------------------------------------------------------------------------------------------------------------------------------------
* crossdev version: 20120531
* Host Portage ARCH: amd64
* Target Portage ARCH: *
* Target System: avr
* Stage: 4 (C/C++ compiler)
* ABIs: default

* binutils: binutils-[latest]
* gcc: gcc-[latest]
* libc: avr-libc-[latest]

* CROSSDEV_OVERLAY: /var/lib/layman/rion
* PORT_LOGDIR: /var/log/portage
* PORTAGE_CONFIGROOT:
* Portage flags:
_ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ -
* leaving metadata/layout.conf alone in /var/lib/layman/rion
_ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ - ~ - _ -

* Emerging cross-binutils ... [ ok ]
* Log: /var/log/portage/cross-avr-gcc-stage1.log
* Emerging cross-gcc-stage1 ... [ ok ]
* Log: /var/log/portage/cross-avr-avr-libc.log
* Emerging cross-avr-libc ... [ ok ]
* Log: /var/log/portage/cross-avr-gcc-stage2.log
* Emerging cross-gcc-stage2 ... [ ok ]

Installed dev-embedded/arduino-1.0 USE="java"
emerge arduino

Installed rxtx-2.2_pre2
emerge -1 rxtx

Installed avrdude
emerge -1 avrdude-5.11.1

and checked I'm in the right groups. I can now select Uno and /dev/ttyACM0 and when I select upload I get no errors and all the correct lights light up on the Arduino only the code doesn't work. I also get the same result with a Duemilanove.
I'm only using the blink example sketch but I just get the onboard pin 13 led permanently lit, it should blink but doesn't! I've tried other Arduino boards and they work ok when I use my laptop with Ubuntu but Gentoo seems to not work correctly.
Any ideas anyone?

It would be nice if you guys add the information from this thread to the Gentoo Wiki!

I just discovered after much head-wall contact that having the sabayon-distro overlay enabled will cause the 'crossdev avr' step to fail. It was complaining about masked packages and "missing IUSE: libffi". Disabled the sabayon-distro overlay and now it's happy.

[edit]
Sigh.. for several hours now I have been trying to install arduino:

Thank you for the thread! I just purchased an Arduino Uno and I'm trying to set up my Gentoo (Funtoo) box to run the IDE.
azzerare ~ # uname -a
Linux azzerare 3.2.12-gentoo #3 SMP Fri Apr 13 05:16:30 PDT 2012 x86_64 AMD Athlon(tm) 64 Processor 3400+ AuthenticAMD GNU/Linux

I'm stuck here.
!!! All ebuilds that could satisfy "dev-embedded/uisp" have been masked.
!!! One of the following masked packages is required to complete your request:
- dev-embedded/uisp-20050207-r1::gentoo (masked by: ~amd64 keyword)

This is my /etc/portage/package.unmask

>=dev-java/rxtx-9999
>=dev-embedded/uisp-9999

package.unmask is the only /etc/portage/ file I have not put in a directory.

Here is the error:
emerge arduino
Calculating dependencies... done!

!!! All ebuilds that could satisfy "dev-embedded/uisp" have been masked.
!!! One of the following masked packages is required to complete your request:
- dev-embedded/uisp-20050207-r1::gentoo (masked by: ~amd64 keyword)

(dependency required by "dev-embedded/arduino-1.0[java]" [ebuild])
(dependency required by "arduino" [argument])
For more information, see the MASKED PACKAGES section in the emerge
man page or refer to the Gentoo Handbook.

Any ideas?

My system is a 32bit setup, but I just bypassed all the compiling and grabbed the tarball from arduino.cc:

http://arduino.cc/en/Main/Software

Set up the user to be in the uucp,tty and usb groups and just ran the arduino binary in the arduino-1.0.1 directory. That has worked just fine for me with my Duemilanove and took about two minutes to set up. No fuss, no muss.

Just because gentoo is a "from source" distro, that doesn't mean you always have to do that for everything on it. Sometimes using a binary is ok.

Cool. I'll be interested to hear how it works out.

Good luck.

I've found a few posts dating back to 2009/2010 running into the same bug:

Does gentoo have an overlay for gnoduion?

http://gnome.eu.org/index.php/Gnoduino

The only things to take care are these:

[oliv3r]

I would suppose there is an overlay.

In any case, this thread was about one of the dependencies and whether is bugged on Gentoo or flawed by design

I guess if nobody can respond on this thread whether it is; i'll just open a bug report about it.

For Arduino UNO 2017 update

First, prepare local overlay:

And two more tweaks.

To fix IDE menu font problem:
run before IDE launching
