Cannot Install package from Synaptic...

[alexvader]

Hi Forum,

I am planning to build a LiveDVD with applications intended for Mechanical Engineering;

Some of them are in the Repos, some have been built from source on other systems ( I use Slackware on my work as Engineer ) so I can easily rebuild them in Knoppix, as soon as I have the needed libs ( binaries and headers ) to link them, and some are only released as Binaries... either for the x86 or the x86_64 arch.

My apps will be Cad applications,
FEA and FVM software,
Math prototyping applications,

stuff like BRL-CAD, Code Aster, Salome, Calculix, Ofelie, DealII, OpenFOAM, Octave/QtOctave, FreeMat, K3d, Blender, Syrthes, Code Saturne, Netgen, Gmsh, Mayavi2, ParaView, Visit, gerris flow solver, GFSView, OpenCascade,...

My questions are :

Since I am supposed to build lots of things from source, I will need the support of some libraries and applications to do this... Since Knoppix, Unlike Slackware or Arch has automatic package management, I use Synaptic to install these prerequirements... yet some of them cannot be installd, despite the fact that they show up in Synaptic after updating the exixting repos...

This is strange... :( I am using Knoppix 6.2 LiveDVD ...

Must I enable some additional repos to have the environment to build the stuff I want, so as to have it installed in a chroot, prior to create a bootable iso image...?

Why do the demos in Scilab fail to run in a Live session...?

Is there any planned release of a Knoppix 6.2 x86_64....?

... I guess this is all.... for now... :D

I'm no expert on this, but I'll take a swing at it, as no one else has. It would definitely require a hard-disk installation, as I understand the re-mastering methodology. This introduces some definite quirks in Knoppix functionality, as it is intended to be used off the DVD/flash. One option would be to do your initial testing with a flash version, which merges the filesystem from the KNOPPIX directory with your persistent store, and still acts much the same as a DVD version. Once you have it as you want it, then you could use that experience (and some notes you carefully kept on that path!;)) to guide you in creating it as a hd-installed variant, which can then be made into a DVD.

Possibly a problem related to the path used to store things; chroot could change what that needs to be, or it may be just HD install versus DVD issue.

I think I have the same appetite for using Synaptic or even apt with the LiveCD.
I just never quite noticed that mine doesn't work with the LiveCD, even though its
right there on the menu. Mine fails somewhere along the way of resolving
sources and/or having 'sufficient memory'.

I suspect it is not expected to work in Live mode, but I didn't know that.
If so, a synaptic warning screen might be in order to educate those naifs
such as I. Especially so, considering Knoppix is usually thought of as a
LiveCD and not necessarily or even usually as a means of achieving an
installed system.

I run into the same thing on occasion, both with aptitude and synaptic - I'm fairly sure my encrypted merge-file is getting filled up (this is with the "poor man's install" variant.) I need to make a new (larger) one and copy the old one's contents over, I guess. Someday...
