Building Amarok on one machine, running it on another ...

[Bernd Wechner]

Jacobo,

I am indebted to your keen eye! The second machine is a Core i5 CPU and 
was running 64 bit Windows 7 until recently. I would appear that when I 
installed Linux MINT I somehow got a 32 bit Linux installed without 
noticing.  I shall endeavour to correct that and see if things improve. 
But from what I'm reading it would seem:

  * 32 bit and 64 bit binaries differ
  * 32 bit binaries will run on a 32 bit or 64 bit OS (generally)
  * 64 bit binaries will not run on a 32 bit OS only on 64 bit OS
  * By inference there are 32 bit and 64 bit .deb packages and the
    package manager (apt) chooses the appropriate one.

Do forgive my learning curve here. Not meaning to waste anyone's time 
getting up to speed on how best to contribute. Have not worked actively 
on Unix/Linux systems since about 1993 bar a few sojourns and much has 
changed of course (and much hasn't - vi is still it seems popular ;-).

Regards,

Bernd.
