<div class="moz-cite-prefix">Hi,<br>
<br>
Great that you've get it works.<br>
The crashed was caused by 2 reasons:<br>
<br>
1. If you're running latest kernel (e.g Ubuntu 16.04), the crash
is caused by the older <span style="color: rgb(0, 0, 0);
font-family: "Open Sans", sans-serif; font-size: 16px;
font-style: normal; font-variant-ligatures: normal;
font-variant-caps: normal; font-weight: normal; letter-spacing:
normal; orphans: 2; text-align: left; text-indent: 0px;
text-transform: none; white-space: normal; widows: 2;
word-spacing: 0px; -webkit-text-stroke-width: 0px;
background-color: rgb(255, 255, 255); display: inline
!important; float: none;">libgomp.so library distributed under
Scilab 6 binary. This problem could be resolved with the OpenCV
installed as along the installation the latest libgomp.so would
be installed to the system as well.<br>
<br>
2. If you're running an older version </span><span
style="color: rgb(0, 0, 0); font-family: "Open Sans",
sans-serif; font-size: 16px; font-style: normal;
font-variant-ligatures: normal; font-variant-caps: normal;
font-weight: normal; letter-spacing: normal; orphans: 2;
text-align: left; text-indent: 0px; text-transform: none;
white-space: normal; widows: 2; word-spacing: 0px;
-webkit-text-stroke-width: 0px; background-color: rgb(255, 255,
255); display: inline !important; float: none;">(e.g Ubuntu
14.04) , the crash is caused during the loading of the IPCV
library which is compiled with newer version of gcc.<br>
<br>
Usually in linux, a lot of codes/program will just ask the user
to download the source and recompile on the system itself. This
will eliminate the issue of crashing. Another way is packaging
the libraries into the software package, which could be a more
complicated process for the developer. <br>
<br>
For the problem you faced, it is definitely not the atoms portal
issue. Atoms portal does not handle the third parties library an
atoms-module required, and the dependencies of the module which
could also crashed with the version of libraries carried by the
Scilab binary.<br>
<br>
So with all these problem, I tried to come out with the "less"
effort way for the user to make it works on linux, still causing
crash for the first time, but with extra 1-2 steps will solve
the problem. <br>
<br>
Thanks.<br>
<br>

<pre wrap="">Answering my own message: It seems that core dump & segfault are almost part of the install process described here: <a class="moz-txt-link-freetext" href="http://scilabipcv.tritytech.com/2017/03/17/installation-of-scilab-ipcv/">http://scilabipcv.tritytech.com/2017/03/17/installation-of-scilab-ipcv/</a>
I followed these recommendations and I can restart scilab without a segfault.
I have the feeling there is something wrong with such an install process (install prerequisite, use atoms, crash, do some hand tweaking, pray).
As far as I remember, image processing toolboxes have always been a pain to install.
Why is this the case?
Is the atoms system inadequate?

<pre wrap="">Hello,
atomsInstall("IPCV") didn't work right away, and I tried in more than
one computer. Although, after usingatomsSystemUpdate(), it worked.
So, thanks for the quick reply. And good work. Now, I can proceed with
my research.

Well I was less lucky than you: this package crashes a fresh install of scilab 6.0:
tar -xvf scilab-6.0.0.bin.linux-x86_64.tar.gz
scilab-6.0.0/bin/scilab
--> atomsInstall('IPCV')

<pre wrap="">hi,
you might want to try:
--> atomsInstall("IPCV")
a new module which is base on SIVP with more functions, just uploaded
about a day ago.
Cheers!

As far as I can see from atoms.scilab.org, neither SIP, nor SIVP
(Scilab Image and Video Processing toolbox) are available at all for
Scilab 6.0 right now. The latter has less time since last update
released (0.5.3.2 in 2014), but it was still intended for Scilab 5.x.
Best regards,
Viktor
