 Posted: Sat Mar 09, 2013 5:18 am Post subject: Writing an ebuild for Simon-0.4 |
 |
|
Hi,
I'm trying to write an ebuild for Simon, voice recognition software. So far, I have written an ebuild of one of its dependencies, pockesphinx:
| Code: | # Copyright 1999-2010 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: /var/cvsroot/gentoo-x86/app-accessibility/pocketsphinx/pocketsphinx-0.8.ebuild,v 1.1 2013/03/09 02:03:03 beandog Exp $
EAPI="2"
inherit cmake-utils
DESCRIPTION="Speech recognizer library written in C"
HOMEPAGE="http://cmusphinx.sourceforge.net/"
SRC_URI="mirror://sourceforge/cmusphinx/${P}.tar.gz"
#SRC_URI="http://aarnet.dl.sourceforge.net/project/cmusphinx/pocketsphinx/0.8/pocketsphinx-0.8.tar.gz"
LICENSE="GPL-2"
SLOT="0"
KEYWORDS="~amd64 ~ppc ~x86"
IUSE="debug"
RDEPEND=">=app-accessibility/sphinxbase-0.8"
DEPEND="${RDEPEND}"
DOCS="ChangeLog README"
src_configure() {
econf
}
src_compile() {
emake
}
src_install() {
emake DESTDIR="${D}" install
}
|
My problem is that Simon itself is a lot more complicated. The build script that is provided wants to do stuff that I have no clue how to translate into ebuild language:
| Code: |
mkdir build 2> /dev/null
cd build
cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
make
su -c 'make install && ldconfig'
kbuildsycoca4
|
I have tried several things, like an ebuild that doesn't specify any build instructions (does not compile), or one that uses the kde4-base scripts (fails), and other stuff. The only way it works is a manual compilation, i.e. not as an ebuild. Can you help? Thanks
This version of Simon is available at http://simon-listens.blogspot.com.

Why did you set pocketsphinx to inherit cmake-utils? Based on the ebuild you provided, pocketsphinx appears to use autotools, not cmake.
For Simon, could you post exactly what you tried? Based on the functionality provided by cmake-utils, it looks like most or maybe all of the steps you describe should have been executed for you as default phases. |

Hello Keba and Hu,
Based on your conversation, I tested successfully the following pocketsphinx-0.8.ebuild:
| Code: |
# Copyright 1999-2013 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $
EAPI=5
DESCRIPTION="Speech recognizer library written in C"
HOMEPAGE="http://cmusphinx.sourceforge.net/"
SRC_URI="mirror://sourceforge/cmusphinx/${P}.tar.gz"
LICENSE="GPL-2"
SLOT="0"
KEYWORDS="~amd64 ~X86"
IUSE="debug"
RDEPEND=">=app-accessibility/sphinxbase-0.8"
DEPEND="${RDEPEND}"
DOCS="ChangeLog README"

Well, there you have a rudimentary but working version:
| Code: |
# Copyright 1999-2013 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $
EAPI=5
inherit kde4-base
SRC_URI="http://download.kde.org/stable/simon/${PV}/src/${P}.tar.bz2"
DESCRIPTION="Open-Source Speech Recognition"
HOMEPAGE="http://simon-listens.blogspot.com/"
LICENSE="GPL-2"
KEYWORDS="~amd64 ~x86"
SLOT="0"
DEPEND="x11-libs/qwt"
|
You will have to add some use flags and other dependencies that will be pulled by them. You will have to add a custom src_configure() function where you define a mycmakeargs array. Please check some KDE4 ebuilds like, say, kde-base/okular, to see how to get things done. By the way, you just see how cool is Gentoo build system and eclasses - so many things you don't have to care since someone else already did. 
Good luck!
EDIT: The program for which you created an ebuild seems to be an optional package.
EDIT2: Added license info to the ebuild. |

Thanks leo.the_zoo!
Adding some more stuff to simon-0.4.0.ebuild:
| Code: |
# Copyright 1999-2013 Gentoo Foundation
# Distributed under the terms of the GNU General Public License v2
# $Header: $
EAPI=5
KDE_HANDBOOK="optional"
inherit kde4-base
DESCRIPTION="Open-source speech recognition program for KDE"
HOMEPAGE="http://www.simon-listens.org/"
SRC_URI="mirror://kde/stable/${PN}/${PV}/src/${P}.tar.bz2"
LICENSE="GPL-2"
SLOT="4"
KEYWORDS="~amd64 ~x86"
IUSE="kdepim libsamplerate opencv"
RDEPEND="media-libs/alsa-lib
x11-libs/qwt
app-accessibility/pocketsphinx
kdepim? ( kde-base/kdepimlibs )
libsamplerate? ( media-libs/libsamplerate )
opencv? ( media-libs/opencv )
"
DEPEND="${RDEPEND}
sys-devel/bison
dev-util/desktop-file-utils
sys-devel/gettext"
src_configure() {
mycmakeargs=(
$(cmake-utils_use_with libsamplerate)
$(cmake-utils_use_with opencv)
$(cmake-utils_use_with kdepim)
)
kde4-base_src_configure
}

- But I can't find qaccessibility-client in gentoo, It seems to be an optional dependency.
- I think pocketsphinx is mandatory, as this is the speech recognition engine
EDIT: reordered DEPEND/RDEPEND

I also noted lack of qaccessibility-client but did not care too much since if that was critical, I'd expect ebuild to exit with a proper error message.
I have no knowledge on speech-recognition, I only wanted to help you to start up with writing a proper ebuild and I'm happy it worked.
Usually a detailed list of dependencies can be found somewhere in documentation attached or project's website.
I wish you good luck with writing and once you have it finished, you may think of making it find the way to Portage tree. |
