Hugin Compiling Gentoo

Preface

These are instructions to build hugin and the whole set of helper applications required from CVS/SVN.

UPDATE: Hugin 2010.2.0 is now stable in portage. If you prefer a in-portage solution instead of the bleeding edge, you should just 'emerge hugin'. There are also some newer but unstable versions. For recent results see package page at [1]

These instructions are work in progress. They're tested on x86 only (though amd64 should work just fine). (Maybe ppc as well. If you try on ppc, please tell me if it works or not.)

If anything does not work: Bugs

Setting up the overlay

Note: The overlay listed below does not appear to be available.

If you've never worked with a overlay, please read http://www.gentoo.org/proj/en/overlays/userguide.xml (especially the section on layman) to get an idea of what we're doing here.

The next steps are:

• Installing layman (if you haven't already).
• Add the overlay listing to layman's config.
• Add the overlay using layman.

First sudo, so you have sufficient permissions:

sudo -s
(enter your password)

Install layman (IF YOU HAVEN'T ALREADY DONE SO):

emerge -av layman
echo "source /usr/portage/local/layman/make.conf" >>  /etc/make.conf

Add the overlay listing: Open /etc/layman/layman.cfg in your favourite editor and change:

overlays  : http://www.gentoo.org/proj/en/overlays/repositories.xml
            http://pani.webhop.org/download/overlays.xml

Save and exit.

Add the overlay using layman:

layman -f
layman -a panotools

Run "layman -S" (or eix-sync if you have it installed and configured to sync layman overlays) periodicaly for new updates.

Unmasking

The versions in the overlay are masked as unstable. You'll have to unmask them:

Open /etc/portage/package.keywords (if it doesn't exist, create it) and add the following lines:

=media-gfx/hugin-9999 ~x86
=media-gfx/enblend-9999 ~x86
=media-libs/libpano13-9999 ~x86
=media-gfx/autopano-sift-C-9999 ~x86

For more information on unmasking, have a look at the Gentoo Handbook.

Installing

Now the fun part! Run

emerge -av hugin

enblend-staging

If you know what you're doing and want to install enblend from Christoph Spiel's -staging branch, you can do:

emerge --unmerge enblend
emerge enblend-staging

Staying up to date

Run "emerge -av -1 hugin enblend libpano13 autopano-sift-C" regularly to build the latest versions.

You could also use the update-live-ebuilds script that upgrades only if something actually changed.

If you are running sys-apps/portage-2.2* you can run emerge -av @live-rebuild to rebuild all your live packages.

Bugs

For ebuilds from the Gentoo portage tree, Gentoo's Bugzilla is the way to go.

Please DO NOT report overlay-related bugs there. Instead, please contact me directly.
