Hello Werner,

Well I followed you instructions to the letter (well almost) I downloaded
the qt-x11-free-beta2.tar.gz (which took all of 2 hours with my very slow
connection).  I tried modifying your instructions for the RPM version I had
downloaded earlier but that failed miserably.

I followed you instructions exactly till I got to this line:

"ls -s qt-x11-free-3.0.0.beta2 qt3"

and I got the following error:

"No such file or directory"

I checked and triple checked for spelling mistakes (there were none).  So,
why am I getting this error?

I then renamed the directory to "qt3" using the "mv" command (as was listed
in the INSTALL file) and kept following your instructions.

Well, after 16+ hours of compilation, over 3 days (I only have a 200 MMX,
well I am poor) - much to the angst of the rest of the family members who
use Windows - I kept following your instructions.  I wish the
instructions had been for the RPM versions.  Much less troublesome and only
takes about 1 minute to get the files.

Oh well, onwards and downwards!

I changed the directories to the Documentation and the Qt2.x Directory as
you said to do.  Then I created a new KDE Mini project - an almost empty app
that I can add to.  I didn't add a single line of code at all.  It compiled
fine, but when I went to Make the app, the following error message was

gmake  all-recursive

I have no idea what this all means, let alone how to fix it.  So now I ask
what do I do next??

Can I fix this problem?  How??
Is my computer too underpowered to run KDevelop + Qt3?
If yes, are there any other IDE's that I could use to make KDE and Qt3

If anyone can help here is a big THANKYOU in advance.
