Hi,

I just want to ask a question about installing simbamond software on Gentoo Linux system.

I have a Raspberry Pi 2 Model. On it Gentoo Linux, and a Moodle system are running.
I wish to get this MoPi to serve as UPS for my RPi.

Only do not know how can one install the simbamond debian package here, on Gentoo Linux?

I ask the question:
"Can I expect a simbamond daemon which is running on a Gentoo linux too?"
the developers, but get an answer:
"There's nothing very debian-specific in the package -- I'd just google "installing .deb on gentoo" and see where that gets you?
best"

So, what can I do to achieve my goal with simbamond?

paul_chany,

Fetch the source from git then build and install by hand.
When you do that, software should really install to /usr/local.
This package won't do that, which is a bad thing. You might want to modify the makefile.

I have now the MoPi hardware at my hands. :D
I am willing to install this on to my Gentoo system now.
Here are few lines in makefile in simbamon directory:
Code:
VERSION=4.1
NEXT_SNAP=1
P=simbamond
D=simbamon
MOPI=mopi
MOPICLI=mopicli
MOPIAPI=mopiapi.py
PD=package/$(VERSION)
INSTALLED_FILES=\
  $(DESTDIR)/usr/sbin/$(D) \
  $(DESTDIR)/usr/sbin/$(MOPI) \
  $(DESTDIR)/usr/sbin/$(MOPICLI) \
  $(DESTDIR)/usr/sbin/$(MOPIAPI) \
  $(DESTDIR)/etc/init.d/$(P) \
  $(DESTDIR)/etc/default/$(P) \
  $(DESTDIR)/usr/share/man/man8/$(D).8.gz \
  $(DESTDIR)/usr/share/man/man8/$(P).8.gz \
  $(DESTDIR)/usr/share/man/man8/$(MOPI).8.gz \
  $(DESTDIR)/usr/share/man/man8/$(MOPICLI).8.gz \
  $(DESTDIR)/usr/share/man/man8/$(MOPIAPI).8.gz

How can I modify $(DESTDIR) variable?

paul_chany,

DESTDIR looks like an environment variable. Its normally empty, so its default value is "" (the empty string)

Random example from your post.
Code:
 $(DESTDIR)/usr/sbin/$(MOPI)
and we see that
Code:
MOPI=mopi

Taken together that expands to /usr/sbin/mopi, which is what you might expect.

Since the package does respect DESTDIR, but does not provide an easy way to install to /usr/local, you could instead write an ebuild for it so that Portage can manage it when it is installed to /usr.

I wish to write an ebuild for this, but have not enough spare time ( because I am a teacher and teaching they lost me a lot of my time ).
However I do not write any ebuild so far.. but if somehow find time for this then I will try to write it.

If you need help writing an ebuild, we can try to guide you. If the installation is simple enough, someone might write the ebuild for you.

OK
I'm reading now followings:
https://wiki.gentoo.org/wiki/Ebuild
https://wiki.gentoo.org/wiki/Basic_guide_to_write_Gentoo_Ebuilds
Please tell me how to start writing ebuild for simbamon, a Simple Battery Monitor daemon?
Eg. should it hase name like: app-misc/simbamon or sys-power/simbamon ?
So I am following the Gentoo Wiki Ebuild.
So far did followings:
Code:
mkdir -p /usr/local/portage/sys-power/simbamon
cd $_
cp /usr/portage/header.txt ./simbamon-1.0.ebuild
nano simbamon-1.0.ebuild

Code:
# Copyright 1999-2016 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Id$

EAPI=6

DESCRIPTION="a Simple Battery Monitor daemon for projects like Mobile Pi ( MoPi ) -- http://pi.gate.ac.uk/mopi"
SLOT="0"

HOMEPAGE="https://github.com/hamishcunningham/pi-tronics/tree/master/simbamon"

SRC_URI=""

Code:
ebuild simbamon-1.0.ebuild manifest clean merge
As you can see I do not know what to put in SRC_URI?
Because the simbamon code is a part of the pi-tronics and only pi-tronics is packaged into a ZIP archive:
https://github.com/hamishcunningham/pi-tronics/archive/master.zip

OK I get help on #gentoo channel and the ebuild looks like this:
/usr/local/portage/sys-power/simbamon/simbamon-1.0.ebuild
Code:
# Copyright 1999-2016 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Id$

EAPI=6

DESCRIPTION="a Simple Battery Monitor daemon for projects like Mobile Pi ( MoPi ) -- http://pi.gate.ac.uk/mopi"
SLOT="0"

SRC_URI=""

HOMEPAGE="https://github.com/hamishcunningham/pi-tronics/tree/master/simbamon"

EGIT_REPO_URI="https://github.com/hamishcunningham/pi-tronics/tree/master/simbamon"

LICENSE="GPL 3 or any later version ( unless otherwise stated ) ."

KEYWORDS="~alpha ~amd64 ~arm ~hppa ~ia64 ~ppc ~ppc64 ~s390 ~sh ~sparc ~x86"


I can install this ebuild with command:
Code:
ebuild simbamon-1.0.ebuild manifest clean merge

But, when I run it on a shell, I get this message:
Quote:
/usr/local/usr/sbin/simbamon: line 22: /lib/lsb/init-functions: No such file or directory

So I get again help on #gentoo channel, but only that, that where to find about the /lib/lsb/init-funtions script.
Look here: http://www.linuxfromscratch.org/lfs/view/stable/scripts/apds02.html
From here I do not know how to proceed further?
