[Scilab-users] Sci-IPOpt updated

[CHEZE David 227480]

Hello Stéphane,
I’ve just make an attempt to install the Sci-IPOpt toolbox from atoms on windows_10_64bits OS, following your recommendations below. I got message that the fix (after exec windows_ifort_fix.sce) was successfully applied but once I restart Scilab (6.1.0 release), the module fails to load with the message:
Start SciIPOpt
                Load gateways
atomsLoad : Une erreur est survenue au cours du chargement de 'sci_ipopt-1.0':
                exec: error on line #18: "link : La bibliothèque partagée n'a pas été chargée: Unknown Error"

nb: I’ve quite recent Intel visual fortran composer xe (2018) installed on this machine which may interfere with the fix ?

Regards,

David

Hello,

This year Christmas arrived in september: although Windows really sucks, I managed with the help of Antoine to build a version of the toolbox for this operating system. Windows users should be able to install sci_ipopt from the atoms GUI (Optimization category). However, there is a little glitch because the Intel Fortran runtime bundled with Scilab is a little bit outdated and this is a problem for the thirdparty ipopt DLL. Hence, once you have installed the toolbox, loading it after a restart will fail. Hopefully there is an easy fix and I have bundled a little script dedicated to this. Hence, after the Scilab restart and the failing Sci-IPOpt load, just type the following at Scilab's prompt:

--> cd(atomsGetInstalledPath("sci_ipopt"))
--> exec windows_ifort_fix.sce

then restart Scilab: the toolbox should load just fine (run one of the demos to make sure that everything works). The Intel Fortran runtime will surely be updated for the next Scilab release and this fix won't be anymore necessary.

Hello,

The Sci-IPOpt toolbox has been updated and now work (smoothly) for Scilab 6.1. Users needing a serious tool for doing optimization with general nonlinear constraint should give it a try. There is no Windows version for the moment but I hope we will have one before Christmas !

Enjoy !
