Bug 138252 – scicos crashes, from scilab 4.0 ebuild

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Wilfried Holzke 2006-06-27 12:30:35 UTC]

Everytime I click into the scicos-window it crashes and scilab too. 

The build 4 branch should fix this.
http://www.scilab.org/download/index_download.php?page=unstable.php

But I am not able to write a new ebuild for this.

The url of the new source:
http://www.scilab.org/download/unstable/scilab-4.0-b4-20060515-src.tar.gz

My attempt for an new ebuild based on version 4.0:

Most certainly not a bugzilla bug.

[Comment 2 Markus Dittrich (RETIRED) 2006-06-28 13:06:29 UTC]

Hi Wilfried,

Thanks for your report! Is there any chance you could provide a 
patch that fixes this particular issue from the list of fixed bugs at the
link you posted.

Thanks,
Markus 

[Comment 3 justXi 2006-06-28 13:35:59 UTC]

No, I don't have a patch, only the build-4 archive. I tried to get this ebuild to work, but I can't get the part after "echo "Make Install successfull!"" to work.

[Comment 4 Markus Dittrich (RETIRED) 2006-06-29 09:22:44 UTC]

Created attachment 90442 [details, diff]
patch to fix gtk crashes

I can confirm the crashing scicos window. The attached patch fixes this
for me. Please give it a try and report back.

Thanks,
Markus

[Comment 5 justXi 2006-07-03 15:48:20 UTC]

How can I use this patch with an ebuild?
Or do I have to use it with the source manually?

[Comment 6 Markus Dittrich (RETIRED) 2006-07-03 18:06:02 UTC]

Move the patch file into the files directory of the scilab directory
(best in your local portage overlay), add the line

epatch "${FILESDIR}"/${P}-gtk-fix.patch

just below the already existing epatch line, re-digest the ebuild and
then re-emerge scilab.

Best,
Markus

[Comment 7 justXi 2006-07-04 03:33:41 UTC]

Yes, the patch solves the problem.
Thanks.

[Comment 8 Markus Dittrich (RETIRED) 2006-07-04 08:18:58 UTC]

Hi Wilfried,

Great and thanks for testing!
The patch is now in portage cvs.

Best,
Markus
