Subject:Which Linux? 
From:Ian Rogers 
Volume-ID:951028.04 

I'm in the position to buy a Linux for my project's PC in order to use
Poplog, but the question is which Linux?

Redhat have a fairly good looking release, but their image and library
format is ELF. I think the Slackware release uses a.out but I'm not sure.

I'm told that the current Linux Poplog uses a.out format. ELF does seem to
be the up-and-coming format though - so can ISL tell us what the plans are
for an ELF format as that may be the better long term solution (or is ELF
just a fad)?

The difference between the formats is that ELF uses shared libraries but
a.out places everything in the image. This explains Aaron's problem:

I.e. enough Motif was linked into the image to run propsheet, but
something is missing that rc_graphic needs.

With ELF shared libraries people would have to acquire their own Motif to
run anything but Vanilla Poplog.

As far as I know....
