[SOLVED] Scilab doesn't start ...

[mystere88]

I just installed Mageia 3 (dvd iso 32bit) on my nootbook , and added SCILAB (scilab-5.4.0-2.mga3.i586).
No particualr problem during the installation.
Then I do

Code: Select all

[jianfeng@localhost ~]$ scilab

the window stucks and nothing happens.

Next I run SCILBA in debug mode: it finishes with a segmentation fault.

Code: Select all

[jianfeng@localhost ~]$
[jianfeng@localhost ~]$ scilab -debug

I am asking for help... Have searched the forum and found no post on SCILAB.

Thanks.

Very curious stuff this one. Today it is working without my special intervention!
Well, I was troubled by another problem with ibus and then have installed two more packages since then.
ibus-ui-gtk3 and lib-qt3.
My guess is lib-qt3 could have helped. Perhaps SCILAB is "qt application", isn't it? lib-qt3 was missing in my case.

Anyway, it works now and I cannot tell more why. Just tell this for record.
