Building the KDE4 for Slackware 15.0 in the KTown style - a build based on the PBSLACKS patches

nobodino · 02-20-2023, 11:14 AM

-for step, you can create an eigen2-2.1.17 SBo package.
-for rocs, you can create a boost compat package aka this https://slackware.uk/people/alien/sl...-compat/build/ which should include also boost-1.74. For the time being, it includes from 1.76 to 1.81.

Honestly, after the mass build, I did not arrived yet at STEP, but ROCS now fails with this error:

Code:

tmp/kde_build/kdeedu/rocs-4.14.3/VisualEditor/Actions/SelectMoveHandAction.cpp: In member function ‘virtual bool SelectMoveHandAction::executePress(QPointF)’:

...

This does not seems a Boost error, but something regarding Qt.

I use this cmake/rocs file:

Code:

mkdir build
cd build
  cmake \
    $KDE_OPT_ARGS \
    -DKDE_PLATFORM_FEATURE_DISABLE_DEPRECATED=TRUE \
    -DCMAKE_PREFIX_PATH="/usr/lib${LIBDIRSUFFIX}/grantlee051" \
    -DCMAKE_C_FLAGS:STRING="$SLKCFLAGS" \
    -DCMAKE_C_FLAGS_RELEASE:STRING="$SLKCFLAGS" \

    -DCMAKE_CXX_FLAGS_RELEASE:STRING="$SLKCFLAGS -std=c++11 -fpermissive" \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DMAN_INSTALL_DIR=/usr/man \
    -DSYSCONF_INSTALL_DIR=/etc/kde \
    -DLIB_SUFFIX=${LIBDIRSUFFIX} \
    ..

Unfortunately, my friend can't help anymore for the next several weeks, because he has a deadline at job. Seems like the last patch he had time for is the one for elogind support - that's why it was delivered also early. Heck, he made over 20 patches for this KDE4 build - so I can't lament for this.

nobodino · 02-20-2023, 11:37 AM

if you let the original cmake

Code:

mkdir build
cd build
  cmake \
    $KDE_OPT_ARGS \
    -DKDE_PLATFORM_FEATURE_DISABLE_DEPRECATED=TRUE \
    -DCMAKE_PREFIX_PATH="/usr/lib${LIBDIRSUFFIX}/grantlee051" \
    -DCMAKE_C_FLAGS:STRING="$SLKCFLAGS" \
    -DCMAKE_C_FLAGS_RELEASE:STRING="$SLKCFLAGS" \
    -DCMAKE_CXX_FLAGS:STRING="$SLKCFLAGS -std=c++98" \
    -DCMAKE_CXX_FLAGS_RELEASE:STRING="$SLKCFLAGS" \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DMAN_INSTALL_DIR=/usr/man \
    -DSYSCONF_INSTALL_DIR=/etc/kde \
    -DLIB_SUFFIX=${LIBDIRSUFFIX} \
    ..

you will see a bunch of boost errors like this one:

Code:

/usr/include/boost/math/policies/error_handling.hpp:833:48: error: expected initializer before ‘noexcept’
  833 | std::pair<T, T> pair_from_single(const T& val) BOOST_MATH_NOEXCEPT(T)

so try to downgrade to boost-1.74.0-x86_64-3.txz (from here: https://slackware.uk/cumulative/slac...slackware64/l/), which was the boost version when kde4 was removed on 8th december 2020.
And tell us the result.

This turns into an archaeological dig, which suits well to LuckyCyborg

Like I said already, for this KDE4 build I prefer very strongly to NOT downgrade the system packages. Heck, even the Qt5 removal (while building the packages) is something which I really like to avoid in future.

Anyway, it's quite clearly that it's a Qt4 value casting error, not a Boost error.

Apparently I have hit a code bug, as in "&" instead of "|" and some return value casting was required for working with the modern Boost.

Unfortunately, this seems to be really the last patch made for KDE4town by this friend of mine in the near future - several weeks he's MIA.

So, the last one package not building is STEP of KDEEDU.

nobodino · 02-20-2023, 01:02 PM

concerning step, there's no need of a patch, the answer is included in the error message:

Code:

-----------------------------------------------------------------------------
-- The following REQUIRED packages could NOT be located on your system.
-- You must install these packages before continuing.
-----------------------------------------------------------------------------
   * Eigen2 (2.0.3 or higher)  <http://eigen.tuxfamily.org>
     Required to build step.

And in slackware-15.0 and after it has been replaced by eigen3 which is a different beast.
Consider building an eigen SBo package, and you'll be able to build step.

But LuckyCyborg has available eigen3 3.2.10 in deps, and this eigen3 has a way of compatibility with eigen2

http://eigen.tuxfamily.org/dox-3.2/E...portModes.html

Depending on the features used, that eigen3 package could be used to simulate eigen2, considering that it is only necessary for this step.

If I'm not mistaken, if he defines EIGEN2_SUPPORT_STAGE10_FULL_EIGEN2_API first, he will get almost an eigen2 API

Indeed, there is also the option of creating an eigen2 package in the style of the one already present in deps, and to be used as is.

Man, I am NOT a C/C++ programmer (all those patches added or presented for this KDE4 build was made by someone else) and playing with a math library is probably the worst way to begin the programming.

So, I for one, I am with @nobodino regarding the solution. Sort of, because just like you said, I intend for now to build a compat library like eigen32 from deps.

True, depending on complexity of usage of this eigen2 compat way of eigen32, your idea certainly is much better. BUT, I will leave this way to be explored by the gentlemen with higher experience in C/C++ programming than me.

LuckyCyborg · 02-20-2023, 02:59 PM

There is the download link for latest KDE4 build of mine, uploaded in two tarballs - one for sources (1.59 GB) and one for packages (1.06 GB).

https://easyupload.io/m/9fghwj

The SHA256SUMS are bellow:

Code:

7bd0780da2bcbda0d5ecb02684d4eeae96cbbbe59db21c3262148b6448e64dcc  kde4town-packages-20230220.tar
f7cc6dfdd6bce825e6a35c48ccf2cce4842b4a79fefa383e992a29f9bf66b259  kde4town-source-20230220.tar

All the patches and builds discussed until now are applied, and just like in the true KTown of Mr. Hameleers, there's also an alldeps.SlackBuild which builds and installs all dependencies for you.

So, what's new? First of all, all KDE4 packages are now built successfully and a new dependency package was added: eigen20 . Also, now the suspend/hibernate works with elogind.

The known issues was already enumerated in this thread - and they are 4 right now.

Long story short, the KDE4 desktop works quite stable and it looks just like you remember, but aren't functional the Plasma widgets addition and the desktop notifications aren't shown. Also, the desktop behaves erratically when it's used the autologin in KDM and the NetworkManager widget and configuration apparently has the interface updates only at startup.

For the NetworkManager Widget probably because of this change in NetworkManager :
"NetworkManager-1.32
Overview of changes since NetworkManager-1.30
=============================================
...
* API CHANGE: D-Bus: remove long deprecated "PropertiesChanged" signal from D-Bus
API. They are replaced by standard "PropertiesChanged" signal on the
"org.freedesktop.DBus.Properties" interface. It is not expected that anybody
is still using this API."

I will look at it.

BrunoLafleur · 02-23-2023, 02:40 AM

I have just put my last version of libnm-qt here https://github.com/BrunoLafleur/pbsl...t-1.0.1.tar.xz

It work on my old Slackware current from april 2021. It should work on the Slackware 15 but I have not tested.

The problem is the deprecated interface I spoke on the previous message. So I have backported some code from networkmanager-qt (which is for qt5 and qt6).I hope it will work.

Thank you very much for your efforts!

I have seen yesterday this tarball of libnm-qt-1.0.1 , BUT it does not compile on Slackware 15.0 with the KDE4 build as seen in the second published tarballs.

First of all, seems that connect() wants SIGNAL/SLOT thingies, so because seemed a relative simple thing, I made the following patch, looking in the libnm-qt-1.0.0 for the similar code which I know that at least it compiled:

How the errors are about missing class functions and I have no idea about how those classes should be, I have stoped there - supposing that I have just walked on some kind of Work In Progress.

My humble suggestion for you is to make a Virtual Machine with Slackware 15.0 where you install everything excluding KDE series. My second published build should compile all KDE4 packages, giving you a KDE4 desktop with those 4 famous issues.

BrunoLafleur · 02-23-2023, 03:32 AM

Sorry I have forgotten to put the last version which I have compiled and put on my machine.
The one you have is broken and is not workable.

I have just upload the good one.

In fact, I think we ended up talking about 3 problems, because it seems that I found a solution for the KDM autologin problems. It's about PAM.

post-install/kde-workspace/config/kde.pamd

Code:

#%PAM-1.0

auth       substack     system-auth

# Uncomment this line to restrict login to users with a UID greater
# than 999 (in other words, don't allow login for root):
#auth       required     pam_succeed_if.so        uid >= 1000 quiet

-auth      optional     pam_gnome_keyring.so
auth       include      postlogin

account    include      system-auth

password   substack     system-auth
-password  optional     pam_gnome_keyring.so     use_authtok

session    optional     pam_keyinit.so           force revoke
session    substack     system-auth
session    required     pam_loginuid.so
-session   optional     pam_elogind.so
-session   optional     pam_gnome_keyring.so     auto_start
session    include      postlogin

post-install/kde-workspace/config/kde-np.pamd

Code:

#%PAM-1.0

auth       requisite    pam_nologin.so
auth       required     pam_env.so
auth       required     pam_shells.so

# Uncomment this line to restrict autologin to users with a UID greater
# than 999 (in other words, don't allow autologin for root):
#auth       required     pam_succeed_if.so uid >= 1000 quiet

auth       required     pam_permit.so

account    include      system-auth

password   include      system-auth

session    substack     system-auth
session    required     pam_loginuid.so
-session   optional     pam_elogind.so
-session   optional     pam_gnome_keyring.so     auto_start
session    include      postlogin

With these PAM files there is no difference between how the KDE4 desktop works with normal login and autologin in KDM.

Please note that I have no idea if KDE4 distributes a PAM module for KWallet.
