I have finally reached a stage where I may have to bite the bullet, grasp the nettle, screw my courage to the sticking place .... and upgrade my Fedora version.

I am currently running Fedora 17.  Which is of course antediluvian. But everything I have seen on this list with respect to upgrading terrifies me.  Disasters seem to lurk everywhere and I haven't the skills to cope with disasters.  Nor do I have access to any support in respect of Fedora.

So, if you will bear with me, I'd like to start off with a preliminary question:

The seeming necessity for upgrading arises from a pressing need to upgrade "R" to version 3.2.0.  When I try to build this version I get a load of error messages (basically coming from gcc I think) like unto:

connections.o: In function `gzcon_write':
/home/rolf/Desktop/Rinst/R-3.2.0/src/main/connections.c:5469: undefined reference to `deflate'

There were also complaints about undefined references to inflate, crc32, deflateEnd, inflateEnd, inflateReset, inflateInit2_, deflateInit2_, compress, uncompress, and zlibVersion, many of which were issued repeatedly.  It finally gave up, saying:

collect2: error: ld returned 1 exit status

People from the R-help mailing list said that the problem lies in some "compression related" libs --- zlib, bzlib, liblzma.

I tried installing zlib and zlib-devel (using yum install) and was told in both cases that my system was up-to-date.  I tried installing bzlib and was told there was nothing by that name.  I then installed lzma and lzma-devel (*that* seemed to work) but it didn't help.  Same undefined references problems as before.

It was also suggested that I try building R-patched.  So I tried; no help there either.

So: Can anyone suggest what I can or should do to overcome this problem *without* having to upgrade?

Given that the answer to my preliminary question is "No", can anyone be so kind as to provide me with a *recipe* for upgrading, expressed in simple-minded terms that I can understand?  Something of the form:

(1) First, do this.

(2) Second, do something else.

(3) Third .....

You get the idea.  I'm afraid vague generalities would be of no help to me, since I am a bear of very little brain and long words bother me.

(I know that step (0) is to make a backup of all my user files.  Which I know how to do and will do.)

A specific question, I guess, is:  Do I use yum for such an upgrade?
(And if so, what is the syntax?) Or do I use fedup?  (And likewise, what is the syntax?)

If no-one wants to write out a set of instructions for me (and admittedly I can see that they may well not want to) can someone point me at such a set of instructions somewhere on the web?  Again, they would have to be expressed in a very simple-minded way.  ("Upgrading Fedora for Dummies".)

Everlastingly grateful for any help that anyone can extend.

cheers,

Rolf Turner
