Bug 21808

in the log of the source package (ruby) I see:

> r1140083 | pterjan | 2017-08-13 18:49:28 +0200 (zo, 13 aug 2017) | 1 line

> tk is gone

and this page http://wiki.tcl.tk/10437 has as title "Tk is obsolete"

I don't know what you should do with your local ruby gui programs, maybe pterjan can tell you, CC'ing him.

If this is likely to affect more users, it'll probably need an entry in the Mageia 7 errata (even if it should really be in the release notes instead of the errata, if obsoleting tk is an upstream decision)

CC: (none) => marja11, pterjan

Yes tk support has been removed from Ruby as of 2.4, but we could package the separate gem https://rubygems.org/gems/tk/ if that seems useful

That would be really useful because my whole life revolves around my personal gui programs.  Have used tk ever since it was invented and my decision to invest in ruby ten years or more ago was heavily influenced by its support for tk.  tk provides things that no other graphics package does, such as an interactive canvas and canvas to postscript support.  It is also very easy to use.

My dependence on tk is such that if I had to rewrite my personal programs I would have to withdraw from QA for many years which at my age means permanently.

So, please do package it as a gem, and remember tkimg.

Thanks.

Just my two cents regarding the "Tk is obsolete" page.

That Wiki entry is some 17 years old. It was probably meant to provoke at the time, but most of the statements are outdated and incorrect now, given the changes made to Tk in the meantime.

I hope that the original Tk package will not be dropped anytime soon because I have Mageia together with some Tcl/Tk applications that I wrote in productive use at my work place.

QA team can't do without you!

@ Pterjan

Do you have time to fix this?

If you don't then please assign back to BugSquad

Cheers,

@ Marja, re QA etc - nice of you to say so - thanks.

Now that more than one voice has been raised, should this bug request be a feature proposal for Mageia 7 or is too small a matter?  That is small in the sense of involving few users; it might mean a lot of extra work for Pascal.

I created the package, it crashes badly when there is no display, but I don't know if this is a new problem

$ ruby -r tk -e ''

Warning:: cannot find Tk library. tcltklib will not be compiled (tcltklib is disabled on your Ruby. That is, Ruby/Tk will not work). Please check configure options.

Can't find proper Tcl/Tk libraries. So, can't make tcltklib.so which is required by Ruby/Tk.
If you have Tcl/Tk libraries on your environment, you may be able to use them with configure options (see ext/tk/README.tcltklib).
At present, Tcl/Tk8.6 is not supported. Although you can try to use Tcl/Tk8.6 with configure options, it will not work correctly. I recommend you to use Tcl/Tk8.5 or 8.4.

Referring to comment 8:

tk-8.6.5-1.mga6

Fortunately, my local applications are still running on mga6, with ruby-tk.

@Pascal
Next step, to try your gem on Cauldron - tomorrow.

Installed tk-devel and tried again.
$ sudo gem install tk
Building native extensions.  This could take a while...
Successfully installed tk-0.2.0

Great work Pascal.

The tk gem installs in Cauldron as well.  With ruby-devel and tk-devel installed there were no problems.  All local ruby/tk utilities are working fine.

Many thanks Pascal.

So this can be marked as fixed?

Sorry for the misunderstanding, I was not expecting you to install the gem, I had actually uploaded a ruby-tk package using it, but if the gem works fine yes this can be close

Resolution: (none) => FIXED
Status: NEW => RESOLVED

Re comment 13.

No misunderstanding - I went ahead out of curiosity - anxious to see if it worked.
