32-bit app on 64 bit system: BricsCAD

[morgano]

I am trying to try out BricsCAD http://www.bricsys.com/
It is only available as 32 bit.
It is also not very good packaged, so not until you start it, it detects it miss a file, i search for what package contain it, install that, then it complains on next file etc, etc...
After some such iterations it now runs on my laptop that have Nvidia graphics and 32 bit Mandriva 2010.2. But that laptop is for other reasons unsuitable.

I intend to use it on my old desktop that now have 64-bit cauldron running:

I installed all packages needed to supply files as i did on my 32 bit laptop system, but more was missing this time.
Actually all was installed already but it was the 64-bit versions and it did not find them, so I installed the 32-bit versions too.

Now it starts up but all text in menues and dialogs are just squares, and in terminal from where it is started i see:

(bricscad: 24529) Pango WARNING**: Failed to choose a font, expect ugly output. engine-type='PangoRendrf Fc', script='latin'

I installed all *pango* packages i could suspect of it possibly needed, but still same problem.

Any idea what could be wrong? Or how to track.

I am not sure what is wrong, because having both 32-bit and 64-bit libs, or Pango in some other way is broken?
I find no pango error in mageia bugzilla
Googleing i found no other hit with bricscad and that error.
Googleing on only that error i find no good advice.

Maybe i should anyway better have made symlinks to the 64-bit versions of the lib files that bricscad said it did not find?

Nobody have yet answered to my question on bricscad forum http://www.bricsys.com/common/support/f ... p?id=18083

You are probably still missing a required 32 bit package. libxfont1 possibly?

You could always run bricscad inside a 32 bit Virtualbox. Not an ideal solution but at least it should work. (At least in 2D)

Thank you for replying.
Yesterday i had already stripped i586 things i installed, and now was about to try linking to 64-bit libs instead, but now saw your reply and revert;
So now i installed the i586 thingys again, and just to verify before installing libxfont1 i tried again, and... now it just worked without libxfont1 !
No idea why... But i also removed other stuff i think i did not need, plus made update and reboot.
Anyhow it works now to *start* Bricscad.

But as soon as I start drawing it exits and tell it need gnome-keyring.
Now why a CAD program need keyring to draw is beyond me...
I have 64-bit installed, and tried to make a symlink link to it in place of the 32-bit lib, but now it give error code about wrong version instead.
32-bit gnome-keyring is not listed in program manager. I will have a go to see what repos are enabled. Will be back later...

If i install in virtualbox, i guess i can in that not install proprietary video driver?
and that is essential for bricscad not to crash. (Yes. Really. Doh.)

Not having used chroot before, i tried that route, but am not "there" yet:
