Openscad: building on KDE Neon

[yeus]

my system:

lsb_release -a
No LSB modules are available.
Distributor ID: neon
Description:    KDE neon User Edition 5.7
Release:        16.04
Codename:       xenial

I did "sudo ./uni-get-dependencies.sh"

it can not do this:

he following packages have unmet dependencies:
libqt5scintilla2-dev : Depends: libqt5scintilla2-12v5 (< 2.9.1+dfsg+1~) but it is not going to be installed
Depends: libqt5scintilla2-12v5 (>= 2.9.1+dfsg) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Please enable universe:

http://packages.ubuntu.com/xenial/libqt5scintilla2-dev

[yeus]

"universe" is already enabled. It didn't want to install anyway ...

it worked by manually installing the package from the provided link above

[t-paul]

Hmm, that's strange. We also just call the system tools, why would that result in a different behavior? Or do you mean you downloaded the *.deb file?

If that's the case maybe they are using a different package source than upstream Ubuntu but that's really a distribution issue then.

[yeus]

yepp. don't really konw what to about it right now
I also opened a bug report here:

https://bugs.kde.org/show_bug.cgi?id=368792

there is another bug realting to the same issue where they apparently recompiled the application and it worked after that but that doesn't work for me :), as I am just trying to recompile it:

https://bugs.kde.org/show_bug.cgi?id=368319

[yeus]

now I get this error (even after I installed the package mentioned above)

/usr/bin/ld: cannot find -lqt5scintilla2

during compilation with qmake openscad.pro and make

after installing the package I get this here (qscintilla2 was on "NotOK" before):

also shows that there are some problems left

[t-paul]

There might be multiple qmake versions as it's possible to install both 4.x and 5.x as default.

Try forcing the Qt5 qmake, Debian uses QT_SELECT=5 qmake ... for that.

[donbright]

qt5 scintilla is completely broken on KDE Neon . i altered the build dependency scripts to use qt4 on kde neon.

i have verified this by installing a kde neon stable user edition https://neon.kde.org/download into a qemu / kvm VM and building per README.md

Just an update: Newer versions of libqt5scintilla2-12v5 and libqt5scintilla2-l10n are available (2.9.3) [1]. They are compatible with Qt 5.6.1 and OpenSCAD 2015.03-1.

Background: I had the problem described with OpenSCAD and Kubuntu 16.04 LTS. The upgrade to Qt 5.6.1 deleted libqt5scintilla2-12v5 (2.9.1) since it broke Qt5.6 - and removed OpenSCAD with it.

I've solved the problem with the updated versions of libqt5scintilla2-12v5 and libqt5scintilla2-l10n. Since they haven't come upon us the official way, I had to download and install them directly.

And voila - OpenSCAD installs and works fine.

For reference.... same issue also with Mint 18.

[yeus]

works ony my system, too !

thx GPHS, to install those two packages download

• https://www.ubuntuupdates.org/package/core/yakkety/universe/base/libqt5scintilla2-l10n
  then
• https://www.ubuntuupdates.org/package/core/yakkety/universe/base/libqt5scintilla2-12v5

and install:
using sudo dpkg -i <package-name>

then
sudo apt install openscad

[core-engineering]

works on my Ubuntu 16.04 ... thanks GHPS and yeus

thanks GHPS and yeus, worked on my KDE Neon 5.9, i just downloaded the deb packages and installed them using dpkg.

For information.

[battaglia01]

Those two packages are no longer available - is there some other way to install them?

[GHPS]

Yes - this has become quite a blind alley. Not only have the package
sources disappeared but also - the tricky part - have the respective
files changed their names.

libqt5scintilla2-l10n -> libqscintilla2-qt5-l10n
libqt5scintilla2-12v5 -> libqscintilla2-qt5-13

I've checked under Kubuntu 18.04 LTS. After adding the
openscad package source (ppa:openscad/releases) the package
lists libqscintilla2-qt5-13 as a dependency.

So the easiest way of installing openscad should be to grab
this version and the latest version of libqscintilla2-qt5.
