google the comp.unix.sco.misc newsgroup for gnutools and gwxlibs

Once or thrice I outlined the shortest recipe to get all the latest 
stuff without making the mistake of installing one of the plethora of 
old junk thanks to the complete disorganization of the sco ftp and web 
sites. Find the one(s) that mention osr507mp5 since that is how you get 
the latest version of gwxlibs.

Sadly, old as those posts are, so little has changed for so may years 
that they are still current! gnutools 507Kj has gcc 2.95 and for various 
reasons that is actually still the last version of gcc that works on osr5.

There is some annoying ugliness you have to handle manually to deal with 
the fact that gwxlibs is by now far newer than the last gnutools, yet, 
gnutools requires gwxlibs be installed first, and some files that were 
in gnutools are now in gwxlibs, so you want to install gwxlibs _after_ 
gnutools to get the current files from gwxlibs instead of the old ones 
from gnutools. There are a couple ways to deal with that. You can 
install an older gwxlibs, then gnutools, then the latest gwxlibs, or 
there is a little trick where you can tell gnutools to ignore it's 
dependencies so you can install gnutools first (and it'll be a broken 
install until you fulfill those dependencies by installing gwxlibs).

Basically, assuming you have osr 5.0.7:
* install the full dev sys from osr507 install cd (free downloadable iso 
is the latest version), forego licensing it.
* install gnutools507Kj, lookup the the temp file hack that tells it to 
ignore the gwxlibs requirement, touch /tmp/gnutools.nocheck or something 
like that, before running the installer.
* install osr507mp5 (this not only includes the latest gwxlibs but all 
of it's other dependencies and fixes the ld linker in case you had the 
broken one from the linker/libs package instead of the full dev sys)

Depending on what you have installed right now, there are variations on 
all of that. I could advise better if I knew what you already have 
installed right now.

You can get a fully working kit, legal and free, even on osr 5.0.5. with 
effort. Possibly even on 5.0.4. Definitely you can at least compile new 
binaries and new libraries that run on 5.0.4

The details and prerequisites differ depending of what you're starting 
from, but that's the overall recipe is those 3 main items, devsys or 
linker/libs package, gnutools, gwxlibs. None of which come from 
skunkware, they consolidate and obsolete many separate and older 
packages that were in skunkware or in plain tar files originally.

"Install NNN" means read the directions for NNN to install it. I haven't 
seen very many VOL packages, be they from skunkware or other, that 
failed to list their prerequisites in the associated readme.
The fact that you had a library problem with that skunkware ImageMagick 
tells me that you most likely failed to read the install directions 
which probably told you to install some Glib-x.x or other package(s) 
first. Don't complain to me about any of the above not working if you do 
that again.

For osr507 it's pretty easy because mp5 does everything at once all by 
itself, including and superseding almost all other patches and updates 
in one easy shot, as well as including gwxlibs and meeting all it's 
prerequisites itself.

But for 506 or lower there are many individual packages and they each 
have their own specific list of prerequisites and each of those has 
their own in turn etc, and order of installation matters.
