compiling on ubuntu 15.10

[Karl-Friedrich R. <ra...@un...>]

I just updated my OS, and found the following problems with
compiling gnuplot:

5.0cvs:
./configure gives a warning

	missing: Unknown `--is-lightweight` option

	configure: WARNING: 'missing' script is too old or missing

seems some of the changes applied to HEAD on 2014-12-16 need to go
in STABLE, too. Building runs fine afterwards.



5.1cvs:
Building is tripped up by the new "jitter" feature, there are
undefined references to `jitter`, `jitter_points`, `save_jitter`
etc. I can provide the full log if necessary.



And, with 5.0 and also HEAD, building --with-qt=qt5 fails with a
complaint "must build your code with position independent code if Qt
was built with -reduce-relocations" " Compile your code with -fPIC
(-fPIE is not enough)"

Here

https://launchpad.net/ubuntu/+source/gnuplot5/5.0.1+dfsg1-3

is ubuntus (i.e. debians) own fix for that.


Best,
  Karl
