Re: [Scilab-users] fmincon toolbox update

[Stéphane Mottelet]

Hi,

These problems are now  fixed in version 1.3.1. For the Windows version, 
if the update of libifcoremd.dll is necessary, the writeability of 
SCI/bin is tested in order to run the update script with admin rights 
only if needed.

Hello all,

 1. My Scilab and all atoms packages are installed in user directories
but the library check at startup on sci_ipopt ask for
administrator access to update. That’s a pity to require that.
 2. The message “This program contains Ipopt, a library for

the documentation and on the DESCRIPTION file. There is no need to
display that at runtime.

Otherwise basic examples are running even if it change the toolbox 
loading order (sci_ipopt after fmincon, scicolpack after sci_ipopt, etc…).

Hi all,

I installed both SciPOpt and fmincon from ATOMS on Scilab 6.1.0 
WIN10-64bits, a few weeks ago and the demos are running properly. I 
had some minor dependencies issues while installing, I don’t remember 
exactly , probably the SciIPopt version was not aligned with the one 
required by fmincon.

Thanks Stéphane for your quick answer

I have tried installing fmincon first, then scicolpack (it works),
then sci_ipopt and it does not work: only
file sci_ipopt_1.3.bin.x64.Windows.zipis downloaded. So it seems:

- first that dependencies are not deal with for the fmincon
distribution that Atoms uses;

- second, that there is some problem using Atoms for loading 
sci_ipopt

Maybe I should not use Atoms, but when it works it is the most
convenient way to download a module.

Hi Eric,

Could you be more precise ? I have I installed fmincon on at
least 10 different machines for testing purposes  (mostly
under Windows 10) and did not encounter any problem. Atoms is,
I must say, a very unstable (not to say crappy) piece of
software and in particular very hard to use smoothly when your
are developing some modules and play e.g. with offline mode.

What I would do first is to uninstall every module then
install fmincon. If problem is still here please help me by

Re: [Scilab-users] fmincon toolbox update

[Lamy Alain]

apifun is in fact loaded through atoms.
fmincon and sci_ipopt are loaded manually (exec(xxx..sce)) using the binary zip 
files.
(I have just run some examples so far)

This is an advertising feature of IPopt and I don't know how to suppress

original releases of sci_ipopt (Yann Collette was the maintainer)

Yes, there were successive versions of  sci_ipot over a short period, 
and since the updates only pop in the atoms gui (not at loading time), 
you can easily miss them. However, the situation is stable since the end 
of april and I don't plan a new release until the end of 2021.
