Re: [Axiom-developer] Axiom and Ubuntu18.04

I see that the problem is more complex than I could imagine.


For the time being, I'll be happy with my workaround: I have built a virtual machine with lubuntu 16.04 and nothing else than axiom.

It works and (hopefully!) always will... ;)


Thanks

Now that I got the termite rant out of the way....

apt-get install gcc-4.8
update-alternatives
alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 1

This installs a working gcc compiler (before the termites arrived).
Beware that this changes gcc to version 4.8 which is NOT what you
probably want.

I am going to fix the 18.04 version but it will take a while.
The gcc libraries appear to have been "reorganized" by some termite.
I have to reverse-engineer that "fix" and figure out how to write new,
"correct" code.

You can, as an alternative, do:

docker pull daly/axiom
docker run -i -t daly/axiom axiom

<rant> Ubuntu used to be a developer platform. However, 18.04 does
not even include 'make' or 'xterm' by default. Some termite has taken
over the teams at Ubuntu, likely trying to turn it into a user-affectionate
platform. Stewart Feldman introduced make in 1976. Everybody and his
grandmother uses it. Now it is no longer standard in a unix-like system?

Termites... the worst bug in software </rant>

Tim, many thanks for your attention.

Sadly, I have issues also with these binaries using functions which worked (and still work) on older versions of axiom.
As an example, consider this simple function which converts an integer in choosen given basis:

toBase: (NNI,PI)-> List NNI
toBase(n,b) ==
  q := n
  l := [] :: List NNI
  while q>0 repeat
   r := divide(q,b).remainder
   l := append([r],l)
   q := divide(q,b).quotient
  l


If I save it in a file (say, r.input) and run it in axiom, I get the following

Yet, it works  smoothly in 16.04 axiom binaries.
