Installing Modnum with Scicoslab

[skippy1729]

I am having problems installing Modnum for use with Scicoslab.

I am using Ubuntu 10.4 LTS 64 bit for AMD processor.

First I tried Scicoslab 4.4.1 (scicoslab-gtk_4.4.1-1_amd64.maverick.deb) and Modnum 4.2.2. When I run Scicoslab, it complains that Modnum was compiled with Scicoslab 4.4 beta 7.

So, I remove 4.4.1 and install 4.4 beta 7. Now I get this message when I launch scicoslab:

Startup execution:
loading initial environment
... Search Scilab version ...
Version of ScicosLab is : 4.4b7
Version of Scicos is : scicos4.4
/home/skippy/modnum_422//interf/scicoslab/../../src/libmodnum_lib.so: wrong ELF class: ELFCLASS32
"/../../src/libmodnum_lib.so")
!--error 236
link: the shared archive was not loaded
at line 55 of exec file called by :
exec(MODNUM+"/interf/scicoslab/loader.sce");
at line 16 of exec file called by :
exec(startup,-1);mclose(startup)
at line 272 of exec file called by :
exec('SCI/scilab.star',-1);;quit

So I try "./configure --with-scisrc=/usr/lib64/scicoslab-gtk-4.4b7" followed by "make all" gives pages of error messages.

Can you suggest which version of Scicoslab and which version of Modnum will be compatible?

Any help or suggestions would be greatly appreciated.

PS There is a installation support email address on the Modnum download page but it is dead.

Hi Skippy,

I just installed Modnum to Scicoslab 4.4.1 under Debian 'squeeze' this afternoon. here's what I did:

- Tried to run the binary of Modnum 4.2.2 and got the same complaint as you did.
- Downloaded the source package instead and ran "exec ('builder.sce');)
- I had to install a few packages (and recursive dependencies) over and above what I already had (your mileage may vary): libgtk2.0-dev libvte-dev libwebkit-dev

It doesn't install to the scicoslab directories, but everything compiles and works beautifully. Give it a go.

Cheers,
The Plumber

More's the point:

Installing modnum into the scicoslab directories so that it loads automatically is done thus:

- Copy the modnum directory tree, as built using the instructions above, into (in my case): /usr/lib/scicoslab-gtk-4.4.1/contrib/
(you end up with the directory /usr/lib/scicoslab-gtk-4.4.1/contrib/modnum, for example)
- Edit /usr/lib/scicoslab-gtk-4.4.1/contrib/loader.sce to add:
exec(SCI+'/contrib/modnum/loader.sce');

Now scicoslab/scicos loads your shiny new modnum blocks, palettes, help, etc.

Cheers,
Pb

Dear Skippy,

Thank you for reaching out regarding your installation issues with Modnum and Scicoslab. I understand your frustration and would be happy to provide some guidance to help resolve this issue.

Firstly, it is important to note that compatibility between different versions of software can often be challenging and may require some troubleshooting. In this case, it seems that the versions you have chosen are not compatible with each other.

Based on the error messages you have provided, it appears that you are trying to use a 32-bit version of Modnum with a 64-bit version of Scicoslab. This is likely the cause of the "wrong ELF class" error.

To resolve this, I would recommend using a 64-bit version of Modnum with your 64-bit Scicoslab. You can try downloading a different version of Modnum, such as 4.4, which is compatible with Scicoslab 4.4 beta 7. You may also need to adjust your configure and make commands accordingly.

If you continue to experience difficulties, I would suggest reaching out to the developers of Modnum for further assistance. They may be able to provide more specific guidance for your particular setup.

I hope this helps and wish you success in getting Modnum and Scicoslab up and running. Science is all about problem-solving, so don't give up and keep experimenting!

Best,
