[PATCH] gnu: kde: Add kdelibs.

[PATCH] gnu: kde: Add kdelibs.

[Andreas Enge]

Hello,

thanks to Ludovic's help with debugging Qt and dbus, I finally have a working
recipe for kdelibs that allows me to compile the KDE "Hello, world"
tutorial at
  https://techbase.kde.org/Development/Tutorials/First_program

It looks like all KDE programs require at least kdelibs, qt, phonon and
automoc4 to compile; but as these are not needed for running the program,
it seems inappropriate to make them propagated inputs.

The configure flags
   "-DCMAKE_SHARED_LINKER_FLAGS=-lQtNetwork -lQtXml"
   "-DCMAKE_EXE_LINKER_FLAGS=-lQtCore"
look like bugs in kdelibs to me; but I wonder if reporting them makes sense.
I sense the answer that we should simply keep Qt in a standard location...

Quite a few of the tests fail, and already the first one (which is a simple
compression and archiver test) hangs at 100% CPU before being killed after
1500s. I can try to run all the tests and see whether there is some useful
output. Otherwise hunting down the test failures looks hopeless.

Comments are welcome.

Andreas

This is good news.  :-)

Right, this is not a reason to propagate them.

Perhaps eventually you’ll find it convenient to have a specific build
system with those listed as implicit inputs, though.

What does it fix?  Would be nice to leave a comment above it.

It would be nice to investigate a bit, but IMO it can be done
incrementally (commit with #:tests? #f and a FIXME, and then see what
can be done.)

At this point, it’s probably better to just use #:prefix.  :-)

I suspect automoc4, bison, flex, and docbook-* should be in
‘native-inputs’.

It’s version 2.0 only?

Hi, when packaging libqtxdg(using cmake and qt5), I find out that I have
to set CMAKE_SHARED_LINKER_FLAGS too to get qt5 into output's rpath.
Then I do a similar build for libqtxdg in nix for comparision, which do not
need to set this variable.

Thanks for your comments!

This sounds like a good idea. I considered a "define" with a list of the
basic packages that every KDE package needs as input, but inheriting a
new build system from the cmake build system sounds like a plan.

As usual, the libraries and binaries are not explicitly linked with the
libraries they depend on. So in a context where the input libraries are not
in /usr/lib, executing binaries fails.

In my private branch I also tried to compile a few KDE packages. The same
problem everywhere: Unless I set an LD_LIBRARY_PATH, they do not find the
necessary KDE and Qt libraries. I think we need a more general solution,
as also witnessed by this:

Maybe someone here can come up with a good solution? In any case, I will
try to discuss with Ludovic and my personal cmake guru.

Agreed; the package is not finished yet, as one of the last steps I should
at least look at the test results (unless many of the about 150 time out
after 1500s...).

Probably so.

Okay.

A bunch of files, yes. I just realise that the truth is really messy:
   http://metadata.ftp-master.debian.org/changelogs/main/k/kdelibs/oldstable_copyright
There is also LGPL2+, "deal in the software without restriction", etc.
and so on.

I'm working on dconf and I had the same problem: the produced binaries
like dconf-edit, but even shared libraries produced by the build would
not find their own companions. Initially I did set LD_LIBRARY_PATH to
resolve the problem.  However, after setting

       #:configure-flags
       ;; Set the correct RUNPATH in binaries.
       (list (string-append "LDFLAGS=-Wl,-rpath="
                            (assoc-ref %outputs "out") "/lib"))

at build time, everything was working fine without having to set
LD_LIBRARY_PATH. That is not in dconf and not in packages build against
dconf's libraries.

What build system does dconf use?

Usually there’s no problem for packages that use Libtool (it sets the
RUNPATH automatically), but there’s almost systematically a problem when
CMake is used (we may not be passing the right options or something, as
Andreas notes.)

Our cmake-build-system sets CMAKE_INSTALL_RPATH_USE_LINK_PATH=True,
which will add the directory of a library given during link time to the
executable or library's rpath.  As was noted before, this is not helpful
if the package does not put those libraries in the link line.

It also sets CMAKE_INSTALL_RPATH to the "lib" directory of the package
output.  I'd imagine this would help with libraries finding libraries
from the same package, but perhaps not.

I'm using glib-or-gtk-build-system (which I'm refining). So, it is
mostly the gnu-build-system. But, in the end of the day, the option is
just a parameter for the linker and I thought it may help... but maybe
not.

It definitely sounds like a good idea. We could add the rpath linker flags
for Qt and for KDE via -DCMAKE_SHARED_LINKER_FLAGS and
-DCMAKE_EXE_LINKER_FLAGS to the kde build system. I would like to give
it a try.

It works! I am attaching the updated kdelibs patch (still not finished,
just for your information; but I took Ludovic's suggestions into account).

So for the kde build system, we could add such lines to code the Qt and KDE
libraries into the rpath. Different submodules (at least kdegames)
also come with their own additional libraries. Anyway, I had the intention
of creating separate guile modules for them to keep a manageable number of
packages per module. So one could imagine a KDE build system, and a local
extended variant in each module inheriting from it.

So is this a solution we should implement, or does anyone have a better idea
or an argument why this would be bad?

Andreas

Apologies if this was already mentioned, but why don’t
-DCMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE and
-DCMAKE_INSTALL_RPATH=$out/lib (in cmake-build-system.scm) lead to
binaries with a RUNPATH?  As Eric said, this should produce binaries
with an appropriate RUNPATH, no?  Or does it only take care of setting
the RUNPATH to $out/lib?

To me, passing -Wl,-rpath would be a workaround for a package-specific
defect.  The ideal solution would be to have cmake-build-system DTRT.

Thanks,

From what I understood, the first variable should have solved the problem.
I set -DCMAKE_VERBOSE_MAKEFILE=ON and compiled ktouch. When running it, it
stops with
ktouch: error while loading shared libraries: libkdeclarative.so.5: cannot open shared object file: No such file or directory

And indeed:

You see lots of "...so" and no "-l...", which is apparently the cmake way of
doing things. But no "-Wl,-rpath" despite
   -DCMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE
Does this mean that this option only honours paths coming from "-l", while
at the same time using "-l" is unusual with cmake?

Actually I do not know about the second part of the sentence, but the first
one seems to be true. When I add
   -DCMAKE_EXE_LINKER_FLAGS=-lkdeclarative ,
the binary ktouch is indeed linked with an additional "-lkdeclarative".
In the link line, we still have "-Wl,-rpath,:::...:::".

Maybe something happens before or during installation. In any case, objdump
now shows:
  RUNPATH              /gnu/store/w931dmcqpkb3sdcxnjpqxdn7qykh3qbr-ktouch-4.14.2/lib:/gnu/store/4k20pkxgvfc22wpcvh6xr26ma4b619ad-glibc-2.20/lib:/gnu/store/k7w7wdpvaqlkwq0ijz9149pqn3lq8a5n-gcc-4.8.3-lib/lib64:/gnu/store/k7w7wdpvaqlkwq0ijz9149pqn3lq8a5n-gcc-4.8.3-lib/lib:/gnu/store/mipmjv4mpsf3rrsk1mbhpqzlw939v6ny-kdelibs-4.14.2/lib:/gnu/store/k7w7wdpvaqlkwq0ijz9149pqn3lq8a5n-gcc-4.8.3-lib/lib/gcc/x86_64-unknown-linux-gnu/4.8.3/../../..

Notice the additional
   /gnu/store/mipmjv4mpsf3rrsk1mbhpqzlw939v6ny-kdelibs-4.14.2/lib ,
which contains libkdeclarative.so.

As I understand things, cmake might relink executables during
installation with the appropriate rpath for the installation directory.
It may also patch the executables rpath in place, replacing the
"::::..." string above with the actual rpath, presumably containing the
directories of the .so's.  Can you tell if any of that is taking place?

Re: [PATCH] gnu: kde: Add kdelibs.

[Andreas Enge]

In nixpkgs, the file for ktouch looks like this:

{ kde, kdelibs, libxkbfile }:

kde {
  buildInputs = [ kdelibs libxkbfile ];

  meta = {
    description = "Touch Typing Tutor";
  };
}

Where do I find the "definition" of what could probably be called the
kde build system?

I do not think it could possibly patch in place, as the ":...:" string is
too short.

Before installing, there is another linking phase. But it also has the
":...:" rpath.

Then there is
-- Set runtime path of "/gnu/store/w931dmcqpkb3sdcxnjpqxdn7qykh3qbr-ktouch-4.14.2/bin/ktouch" to "/gnu/store/w931dmcqpkb3sdcxnjpqxdn7qykh3qbr-ktouch-4.14.2/lib"
which corresponds to
   (string-append "-DCMAKE_INSTALL_RPATH=" out "/lib")

This is for the build where I explicitly gave "-lkdeclarative", and where the
final rpath does contain the path to the kde libraries (but not the path to
the qt libraries, as these were not given with -l, but directly as .so on
the linking line). So the log does not show at which point and how the rpath
is set.

Our ld-wrapper is ineffective when the .so file names are passed
directly like this.  That is, ld-wrapper adds -rpath for any -l switch,
but it does not add -rpath for libraries whose absolute file name is
specified.

That could be easily fixed, but in core-updates.

Uh.  While we can improve ld-wrapper, the best would of course be to get
CMake to do the right thing...

Following our discussion, I think that indeed the flag
   -DCMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE
does nothing at all, and that our ld-wrapper is doing all the work indeed.
