Bug 400219

Hey KDE team,

I am trying to compile the latest plasma stuff.

Using this URL:

https://download.kde.org/stable/plasma/5.14.2/plasma-nm-5.14.2.tar.xz

The cmake-checks fail to find a required package:

"-- The following REQUIRED packages have not been found:

 * Qca-qt5 (required version >= 2.1.0), Support for encryption, <http://download.kde.org/stable/qca-qt5/>"

I have a look at this URL.

https://download.kde.org/stable/qca-qt5/

If you look, the latest release is +3 years old, almost 4
years old.

Age in itself is not necessarily a problem if it compiles,
but it does not compile for me - so I actually am, sort
of, filing two bug reports here. BUT, I mostly only care
about plasma, because that seems to be very frequently
having new releases so I assume it is actively maintained.
Not sure about qca-qt5, but I think you can understand that
the situation is not ideal if plasma itself works fine and
is maintained, but add-ons such as qca-qt5 are not.

Anyway, I will also show the specific error for qca-qt5:

(This is a bit long ... I just paste it for the sake of
completeness... comes after a bunch of ______):

_____

The "RBT::" part is just from my ruby scripts trying to compile
it; the problem comes from /usr/include/features.h which is part
of my local glibc (slackware; glibc version 2.26) and then the
error

  error: 'QIODevice' has not been declared
  void update(QIODevice *file);

Anyway, I am not sure if the KDE team could or should update qca-qt5,
which I guess may be fine too, but perhaps there could be some option
to skip qca-qt5 if things can not easily be fixed. Not sure whether
plasma-nm would still be useful.

I report this just in case - feel free to close this if you wish to.

The rest of plasma compiles quite fine for me now. (If there is someone
available, perhaps qca-qt5 could or should be moved into the regular 
KDE release cycles, but I understand that the amount of manpower is 
not always available; I mostly mean this in regards to fixing any 
problems, more than adding new functionality or feature, to qca*).

Last but not least, my build system:

  Operating System:                  GNU/Linux
  Os Bit Type:                       x86_64
  CPU Model:                         AMD A8-7600 Radeon R7, 10 Compute Cores 4C+6G, 2 cores
  CFLAGS in use:                     -O2 -fPIC -fno-strict-overflow -Wno-error
  RAM:                               15305224 kB RAM (14946.5 MB) (14.6 Gig)
  Screen Resolution:                 1920x1080
  Gcc Version:                       8.2.0
  Glibc Version:                     2.26
  Linux Kernel:                      4.14.12
  Binutils Version:                  2.31.1

PS: Actually just noticed ... 5.14.2 is not yet registered in the bug-components, at the least I can not choose it from the dropdown list,
only 5.14.1. I thus selected "master", but I would prefer using 5.14.2;
I assume this is manually synced. Perhaps if a new kde plasma release
happens, the version could be automatically added onto kde-bugzilla so
that nobody forgets to update it - or "master" may be correct of course
but since the drop down has so many versions listed, I assume it was
simply not yet added. Keep on fixing all bugs, compiling the whole KDE suite has gotten simpler for me, compared to e. g. a year ago - cheers!
