Hello all,

does anyone know if there is an overlay that has OpenTTD with cargodist (as in here: http://wiki.openttd.org/Passenger_and_cargo_distribution ).

I know that I could use git to pull it down and install localy, but I would prefer to keep everything tidy and do it through Portage. So far, I could not find an overlay that has this.

If such overlay doesn't exist, can someone help me write an ebuild for it? I know that I can have local overlays, but I have never wrote an ebuild. I guess I could just grab the normal games-simulation/openttd ebuild and just change from where to download (and save it on a local overlay with a different name, say games-simulation/openttd-cargodist). I guess I should just change this line in the ebuild:

Code:
SRC_URI="http://binaries.openttd.org/releases/${PV}/${P}-source.tar.gz"


The thing is, the cargodist version uses git, and I don't know how to use it beyond "git clone"... So I don't know how to properly replace this line (and the variables PV and P also appear elsewhere in the ebuild, so I guess I would need to change those too).

Thanks for the help!

OpenTTD 1.4.0, with cargodist included, was released on April 1 (no joke!), and the dev team just released 14.1-rc1. I don't know when 1.4.0 will arrive in portage, but several other games are usually in ~arch within hours of the release. Like a kid waiting for Christmas, I'm checking "emerge --sync && emerge -avuDN world" every day for the 1.4.0 package, but still no luck.

step by step, howto reuse current ebuild to build trunk openttd

- download nightly -> http://www.openttd.org/en/download-trunk
- let's pickup current :
Code:
wget http://binaries.openttd.org/nightlies/trunk/r26563/openttd-trunk-r26563-source.tar.xz

- open the file with archive editor (ie: fileroller) and just rename directory in the archive to openttd-1.4.0
- convert xz to gz
Code:
xz -dc < openttd-trunk-r26563-source.tar.xz | gzip -c > openttd-1.4.0-source.tar.gz

- copy converted file to your distfiles directory
Code:
cp openttd-1.4.0-source.tar.gz /pathto/distfiles

- create new ebuild using older one
Code:
cd /usr/portage/games/simulation/openttd
cp openttd-1.3.3.ebuild openttd-1.4.0.ebuild

- add patch for 1.4
Code:
cp files/openttd-1.3.3-cflags.patch files/openttd-1.4.0-cflags.patch

- register new ebuild & patch files
Code:
ebuild --force openttd-1.4.0.ebuild manifest

- just emerge openttd now, remember to update opengfx

For non trunk version (the real 1.4.0) just jump at step "create new ebuild using older one", while creating the manifest emerge will download the source itself

edit: of course next --sync will remove it, better copy it and emerge from your local overlay

@Krinn, thank you very much for your stepwise instructions, and for giving me some courage to do things on my own. I read up a bit about local overlays, and ended up with this copy-and-paste job:

Code:
mkdir -p /usr/local/portage/{metadata,profiles}
echo 'MyOverlay' > /usr/local/portage/profiles/repo_name
echo 'masters = gentoo' > /usr/local/portage/metadata/layout.conf
chown -R portage:portage /usr/local/portage
echo 'PORTDIR_OVERLAY="/usr/local/portage ${PORTDIR_OVERLAY}"' >> /etc/portage/make.conf
mkdir -p /usr/local/portage/games-simulation/openttd
cp -pr /usr/portage/games-simulation/openttd/* /usr/local/portage/games-simulation/openttd
cd /usr/local/portage/games-simulation/openttd/
cp -p files/openttd-1.3.3-cflags.patch files/openttd-1.4.0-cflags.patch
cp -p openttd-1.3.3.ebuild openttd-1.4.0.ebuild
ebuild --force openttd-1.4.0.ebuild manifest
cd
emerge -av openttd


I started OpenTTD, and after a quick in-game upgrade of stuff, which I suppose included the OpenGFX, I'm now in 1.4.0 :D

I just can't believe it's that simple to tweak portage 8O

Edit: Removed "repoman manifest" from the code, as it seems totally unneccessary.
Edit2: -p added to 2 last cp lines to preserve portage as owner.
Edit3: remove old 1.3.3 files
Edit4: Undid Edit3

I ran into a problem today:

Code:
balapapa ~ # emerge -avuDN world                         

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

Calculating dependencies... done!
[ebuild     U  ] sys-libs/timezone-data-2014a [2013d] USE="nls" 385 kB
[ebuild   R    ] media-libs/libsdl-1.2.15-r4  USE="X aalib alsa directfb joystick opengl oss sound%* video xinerama xv -custom-cflags -dga -fbcon -ggi -libcaca -nas (-ps3) -pulseaudio -static-libs (-svga) -tslib (-audio%*)" 0 kB

Total: 2 packages (1 upgrade, 1 reinstall), Size of downloads: 385 kB

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

media-libs/libsdl:0

  (media-libs/libsdl-1.2.15-r4::gentoo, ebuild scheduled for merge) pulled in by
    >=media-libs/libsdl-1.2.13-r1[sound,video] required by (media-video/libav-0.8.7::gentoo, installed)

  (media-libs/libsdl-1.2.15-r4::gentoo, installed) pulled in by
    media-libs/libsdl[audio,X,video] required by (games-simulation/openttd-1.4.0::MyOverlay, installed)


It looks like my overlaid openttd is screwed :(

(Answering myself)

It seems like a trivial change in keywords, replacing "audio" with "sound". I edited my openttd-1.4.0.ebuild and changed the word "audio" to "sound" in the line

Code:
                media-libs/libsdl[audio,X,video]


and then did an

Code:
ebuild --force openttd-1.4.0.ebuild manifest


This apparently has resolved the issue.

It's a wanted feature... https://bugs.gentoo.org/show_bug.cgi?id=357661
So that bug appears because of that change. Glad you fix it yourself ;)

Thanks for the Bugzilla link, which confirms my hunch about the change in use flags. It's also obvious from the official ebuild, updated yesterday:

Code:
balapapa ~ # grep libsdl /usr/portage/games-simulation/openttd/openttd-1.3.3.ebuild
                media-libs/libsdl[sound,X,video]

Submit your ebuild there and get plenty of people thanks, and women falling in your arms while yelling your name...

I did post a link to this thread at the bugzilla a few minutes before your previous reply.

«women falling in your arms while yelling your name» sounds interesting, but I believe that I'm past that age :)
