[Gegl-developer] Binary Download

Björn Salgert — 2013-05-12T17:01:23

Hello everyone,

I am wondering why there is no download of the gegl binary (gegl.exe)
for Windows on the GEGL Website ( http://www.gegl.org/#_download ). I
think this would improve the usability of GEGL a lot.

best regards
Bjoern

Having bindings for the graph API is in any case more useful than having no

The reason for the change is that GI binding toolchain does not for work

Please use the git version of babl/gegl. There are a lot of fixes in
those versions. (I think this is one of the issues that was fixed.)
Thanks!

[Gegl-developer] Funding and Feature Request Management For OpenSource

Boian Mihailov — 2013-04-20T14:41:43

Hi,

We have just launched a site to help existing open source projects
with funding (www.catincan.com). Our goal is to help more open source
projects become self-sustaining and competitive with propriety
solutions. We're hoping you might provide us with some insight by
answering the 3 questions below.

1. Do you have any problems funding your open source project?

2. What would the perfect solution have to help the open source
community gain funding?

3. Would you use a solution like Catincan to fund your project? If no,
why not?

Thanks for your feedback. Hearing from open source developers really
helps us understand what's most important. If you have any questions,
just let me know.

Cheers,
Boian

I don't understand why you were trying to look for source code in
GEGL's repository :) Plug-ins don't necessarily have to be implemented
as GEGL ops. Yes, it's nice, but not necessary. Rewriting them to use
GEGL buffers is sufficient for now. Could you please fix the wiki? :)

Hi Gegl developpers,

I'm the graphic designer who bug you yesterday during your talk at the LGM
2013. I'm a little sorry for my agressive behavior, but it's an important
project to my eyes, so maybe one day you will excuse me.

So, if you want to know more on the Mikado project, here is the link to the
website we freshly set up :
http://mikado.toonloop.com/
We are working on a Github repository too, not yet ready.

By the way, I take a look at the Gegl-server project by jonnor and it may
be a great tool for us. Any way, thanks for your work on Gegl.

See you later around a beer maybe !

[Gegl-developer] Porting GEGL

scl — 2013-04-09T22:38:13

Hi,

as a foundation for the further GEGL porting work, the LGM and GSOC 2013 
I updated the GEGL porting matrix in our developer wiki [1].
Please review.

I think - despite of all the respectable work done - it's no secrets to 
say that the GEGL port has been a topic for long, is still a show 
stopper for version 2.10 and all further work and yet there's still a 
lot to do. Beside others currently 43% of the filters are ported.
Don't get me wrong - I'm not blaming anybody. Let's see how we can boost 
the process.

I think the following could help:
- Get rid of filters that don't match to the product vision or are 
outdated. Priorize the remaining filters. Alexandre wrote a mindstorm 
article [2] in the wiki and I fully agree with it. The LGM is a good 
opportunity to discuss it and also we have the mailing lists and IRC. 
Ask the artists at LGM and in our mailing lists about their needs.
- Focus the 2013 GSOC projects on the GEGL port.
- Port only a set of core functions and let the other functions do their

[Gegl-developer] Research: FLOSS hackers between company andcommunity

Thomas Zerbach — 2013-04-02T09:05:39

The University of Koblenz-Landau (Germany) is looking for participants 
for a research study revolving around the job situation of 
(professional) open source developers. The goal of the study is to gain 
insights on the effect of developers' double commitment to the community 
and the organization. The study is aimed at employed software developers 
who also work with open source code and therefore are to some extent 
dependant on the open source community.

The study already received support by several organizations including 
the Open Source Business Foundation (OSBF), the European Commission's 
Joinup project and various open source projects (e.g. Eclipse) and 
experts (e.g. former Open Source Director at Oracle Gilles Gravier)!

As incentives, participants will be able to contribute to social 
projects for free and can subscribe to receive the research results. For

[Gegl-developer] Biggest Fake Conference in Computer Science

2013-04-02T23:03:48

We are researchers from different parts of the world and conducted a study on  
the world’s biggest bogus computer science conference WORLDCOMP 
( http://sites.google.com/site/worlddump1 ) organized by Prof. Hamid Arabnia 
from University of Georgia, USA.


We submitted a fake paper to WORLDCOMP 2011 and again (the 
same paper with a modified title) to WORLDCOMP 2012. This paper 
had numerous fundamental mistakes. Sample statements from 
that paper include: 

(1). Binary logic is fuzzy logic and vice versa
(2). Pascal developed fuzzy logic
(3). Object oriented languages do not exhibit any polymorphism or inheritance
(4). TCP and IP are synonyms and are part of OSI model 
(5). Distributed systems deal with only one computer
(6). Laptop is an example for a super computer
(7). Operating system is an example for computer hardware


Also, our paper did not express any conceptual meaning.  However, it 
was accepted both the times without any modifications (and without 
any reviews) and we were invited to submit

Re: [Gegl-developer] Building GEGL from git / error: possibly undefined macro: AM_GLIB_GNU_GETTEXT

Michael Henning — 2013-04-01T14:18:22

Try running autogen like this:
ACLOCAL='aclocal -I /gtk/share/aclocal' ./autogen.sh
(add your normal configure options to the end of the command)

Those files (install-sh, missing, config.sub, config.guess) should be
created by autogen, but they aren't being created because it's
erroring out early.

I'm using the GTK+-bundle that contains the corresponding m4 files:

freetype2.m4  glib-2.0.m4  glib-gettext.m4  gsettings.m4  gtk-2.0.m4

Still, I keep getting the same error about missing Macros.


Apart from the macro-problem, the script complains about other missing
files:

install-sh
missing
config.sub
config.guess
... maybe more

These files are available in the BABL git root directory, but not in the
GEGL directory.

I'm not familiar with autogen.sh, autoconf, autotools, etc. but it
seems to me there is missing something in the GEGL tree, not on my
system.

This means that aclocal can't find the m4 files associated with gettext or glib.

If you don't have glib or gettext, you need to install them.

If you do have glib and gettext, you need to find their .m4 files and
add the containing directories to the environment variable
ACLOCAL_PATH (it's a colon separated list).

Re: [Gegl-developer] Problem running GEGL hello-world example

Michael Henning — 2013-03-31T13:56:19

As a general note, you should probably grab a development version from
git, not a release tarball. GEGL has gone through massive numbers of
bugfixes since the release, as it's still under heavy development.
(I'm hoping that will fix the bug you're running into now.)

The gtk+ display op is separate from GEGL itself. You can find it here:
https://git.gnome.org/browse/gegl-gtk/
The op is named "gegl-gtk3:display". (or, if you compile against gtk+
2, it's "gegl-gtk2:display")
There's also a clutter and a qt helper library, if you're interested.

Hi again,

I now compiled GEGL against SDL. I keep getting the same error. Did you
notice this line?:

GEGL-geglmodule.c-Message: Module

I guess it has nothing to do with the gegl:display op, but this might be
the reason why it wouldn't find any display op.

Re: [Gegl-developer] Problem running GEGL hello-world example

Michael Henning — 2013-03-30T22:11:14

The example program uses a gegl:display op. The issue you're running
into is that you didn't compile gegl against any libraries that can
provide the display op.

You can fix this by either compiling gegl with SDL support (there are
SDL binaries for windows online, so that shouldn't be too difficult to
set up), or by modifying the example to save a png file instead of
trying to display a window (I'd recommend you try this anyway, if
you're trying to learn gegl's api).

Feel free to post back with any more questions you have.
