[PATCH v1 0/1] Add support for meson building

[PATCH v1 0/1] Add support for meson building

[Ariel D'Alessandro]

Hi all,

After a couple of RFCs, here's the final patchset adding support for the
meson build system.

All functionality provided by the autotools based build was ported to
meson, except sync-with-kernel. I guess we can add it at some later
point and have this merged anyway.

Native and cross compilation has been tested with several options. Any
feedback, testing or suggestions are welcome. Looking forward to see
this merged in the next release hopefully :-)

Here's a simple comparison between meson and autotools performance for a
native build:

    $ time meson build/
        [...]
        real    0m3.172s
        user    0m2.698s
        sys     0m0.577s
    $ time ninja -C build/ -j4
        [...]
        real    0m19.533s
        user    1m11.860s
        sys     0m7.956s

    $ time (./bootstrap.sh && ./configure)
        [...]
        real    0m19.289s
        user    0m16.448s
        sys     0m2.756s
    $ time make -j4
        [...]
        real    0m55.250s
        user    2m29.425s
        sys     0m10.829s

This patchset was developed on top of v4l-utils tag: v4l-utils-1.20.0:

    commit 3b22ab02b960e4d1e90618e9fce9b7c8a80d814a
    Author: Gregor Jasny <gjasny@googlemail.com>
        Prepare for 1.20.0 release

You can find the patch pushed to the following branch:

Re: [PATCH v1 1/1] Add support for meson building

[Kieran Bingham]

Hi Ariel,

Wow there's a lot of work there! That must have taken quite some effort
between you and Ezequiel!

I've looked through, and about the only thing that stands out to me is
the way you're joining strings.

Meson provides a join_paths() function specifically for that.
Now we're "probably" not going to build this library on anything other
than linux, but I think the function still has merit over the arbitrary
strings which I mis-interpreted for 'divide' at first glance :S

Other than that, I expect we will have to run both build systems in
parallel for some time to allow packaging and other builders to adapt.
That might mean it's a bit more difficult to make sure both build
systems are updated when adding new files or changing the build in anyway.

However, that said - I'm most certainly in favour of this change and
would love to see more meson support, so theres an:

Acked-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

for the principle of this either way, but I don't maintain this library
anyway ;-)

With join_paths() used instead of (I guess it's just plain string
concatenation?):

But that's a whole lot of text, so I'm sure I've probably missed
something. Lets see what more eyes find...

Looks like this should also be join_paths() (noticed below first, and
skipping back to look for other occurences).

you could do

gconv_install = join_paths(get_option('libdir'), 'gconv')

				   install_dir : gconv_install,

Then you can reuse the gconv_install variable here.

Same wherever approrpiate in other build files too.

Why?

Is it too naive to expect that's it's safe to just turn the flip on meson,
and remove autotools?

Everyone doing packaging is already aware and used to meson.

If we add meson as an option and keep autotools supported in parallel,
there's a high change packagers won't notice, so it won't help much. I'd
recommend reaching out to known packagers (major distros, buildroot,
...) to let them know of the move. If any of them requests to have time
to adapt, then we could support both build systems in parallel.
Otherwise, I'd just flip the switch.

Hi,

I've been added in this thread without much context, not sure which
project it's speaking about.

From past experience, distros tend to find many small issues with build
systems, especially debian who have tones of scripts to verify what
changed in the package: a missing installed file, a missing build
option, missing build flag, etc. You can either deal with that and roll
a quick point release to fix any issue they could find, or keep both
build systems for a couple releases while recommending downstream (a
note in ChangeLog) to try the meson build system, making it clear

Another viewpoint is supporting both for a number of releases equates
to kicking the can down the road. A lot of people don't bother with
changes until they're forced to. Consider supporting both build
systems for one release, making it clear autotools will be removed
from the next release. If you imply a sense of urgency, people are
more likely to give it attention. If you imply that it's ok to kick
the can down the road, people will kick the can down the road. Yes,
some people will jump on the move to meson, but it's not just those
people who need to migrate. The best way to get someones attention is
not text in a changelog or readme, it's to deploy changes that break
their build and make them address it. How many times has it been that
upcoming changes were announced well in advance and people still
neglect preparation. As the saying goes, `the squeaky wheel gets the
grease`.

Hello,

thank you for all the work on building v4l-utils with meson.

I'll try to adjust the Debian / Ubuntu packaging scripts to meson. If 
all goes well I'm not opposed to flip the switch after we release a new 
stable version.

I tried to adjust the Ubuntu v4l-utils development scripts on top of the
ariel/mesonbuild-v4 git branch.

On Unbuntu 20.04 I did the following:

mkdir v4l-meson
cd v4l-meson
git clone https://gitlab.com/adalessandro/v4l-utils.git
git clone https://git.launchpad.net/\~libv4l/+git/v4l-utils-packaging
cd v4l-utils
git checkout ariel/mesonbuild-v4
ln -s ../v4l-utils-packaging debian
cd debian
git checkout meson-build
cd ..
dpkg-buildpackage -uc -b -rfakeroot # install build-essential + missing

I noticed the following:
* library symlinks are not in place
   see https://packages.debian.org/sid/amd64/libv4l-0/filelist

* static libraries are missing

* bfd sources did not compile properly (now disabled in my repo):

Let's work on top of this branch:

    https://gitlab.com/adalessandro/v4l-utils/-/tree/v4l-utils-1.20.0-meson-v1

This is the one related to the submitted patch. Further changes will be pushed
to this branch.

Right. Each library target should have soversion and version set in order to
create the proper symlinks. As follows:

    diff --git a/lib/libdvbv5/meson.build b/lib/libdvbv5/meson.build
    index 6bbde1b0..8854a801 100644

BTW, shall we set these fields in meson with the proper version tag?

>

Libraries are defined in the meson scripts as `library`, so they can be built as
static, shared or both, depending on the configuration option `default_library`
(defaults to shared). I think this is fine and we should explicitly set the
option -Ddefault_library=both.

For example, in v4l-utils-packaging:

    diff --git a/rules b/rules

Fixed. Include directories were omitted by clang as they were all passed as a

Hello,

thanks for your helpful suggestions. I made a PR from those: Feel free 
to squash it into yours:
https://gitlab.com/adalessandro/v4l-utils/-/merge_requests/1

When looking at your quoted code with the fixes I'm wondering if you 
forgot to push your branch?

I don't think so because v4l-utils feels more like a mono-repo. Each 
library is versioned independently.

I have some more comments:
* The project version is still at 1.19.0 (should be 1.21.0 for the merge)

* As long as we support autotools and use 'make dist' to create the 
tarball we'd have to add the meson.build and meson_options.txt to the 
EXTRA_DIST of the respective Makefile.am.

* for ir-keytable the following variables are set and forwarded to the 
source code as a preprocessor define:

ir_keytable_system_dir = udevdir
ir_keytable_user_dir = get_option('sysconfdir') / 'rc_keymaps'

It would be nice if we could re-use those as the install-dir base here:
udevdir / 'rc_keymaps'

(But that's nice to have)

* Right now on install we create an empty directory at the 
ir_keytable_user_dir. Are you aware of any mechanism to create this with 
meson? I found https://github.com/mesonbuild/meson/issues/2904 and it 
makes me think that there is no easy way to do so. I could imaging to 
work-around by putting a readme file inside of that directory to have it 
created. That would also explain its reason for existence.

I'm still very fascinated of the very high build speed improvement. For 
me it's down to 8s (with cold cache). Very impressive. Thank you, again!

Thanks,
Gregor

Makes sense, will do that.

BTW, did you try 'meson dist'? Have any comments on that?

Sounds good, let's re-use those variables as much as possible.

Hmm, nope. I don't think there's a way for creating an empty directory with
meson right now. We can achieve what you say using install_subdir() and exclude
the README file:

    install_subdir('user_dir_protocols',
                   exclude_files : 'README.md',
                   strip_directory : true,
                   install_dir : ir_keytable_user_dir / 'protocols')

See

 From a Debian packager perspective the current branch looks really 
good. Only lintian found a small typo:

I: qv4l2: image-file-has-conflicting-name 
usr/share/icons/hicolor/scalable/apps/qv4l2.svg (is PNG)


I guess it's due to that:

qv4l2_icons_files = [
...
     ['qv4l2.png',       'scalable', 'qv4l2.svg'],
]

The Doxygen m4 script provides several features, like:

    $ git grep 'DX_ARG_ABLE(' m4/ax_prog_doxygen.m4
      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(doc, [generate any doxygen documentation],

      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(rtf, [generate doxygen RTF documentation],
      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(xml, [generate doxygen XML documentation],
      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(chm, [generate doxygen compressed HTML
help documentation],
      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(chi, [generate doxygen seperate
compressed HTML help index file],
      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(html, [generate doxygen plain HTML
documentation],
      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(ps, [generate doxygen PostScript
documentation],
      m4/ax_prog_doxygen.m4:DX_ARG_ABLE(pdf, [generate doxygen PDF documentation],

I could port them all to meson and have options for each one. But, do we really
need all of them or just a subset?

For instance, from [0]:

    $ git grep CONFIGURE_FLAGS.*doxygen
      rules:CONFIGURE_FLAGS += --enable-doxygen-man --disable-doxygen-ps
--disable-doxygen-pdf

Only a few Doxygen options are being used there, but I wonder what are other
projects using... how much Doxygen functionality do we need to support here?

Any comments? :-)

Ariel

I think we need html (Debian) and man (Fedora).

I've pushed meson Doxygen support to:
    https://gitlab.com/adalessandro/v4l-utils/-/tree/v4l-utils-1.20.0-meson-v1

The following options were added, supporting html and man.

    # Doxygen options
    option('doxygen-doc', type : 'feature', value : 'auto',
           description : 'Generate doxygen project documentation')
    option('doxygen-html', type : 'boolean',
           description : 'Generate doxygen plain HTML documentation')
    option('doxygen-man', type : 'boolean', value : false,
           description : 'Generate doxygen manual pages')

So, you should get html and man documentation using:

    CONFIGURE_FLAGS += -Ddoxygen-doc=enabled -Ddoxygen-man=enabled

Note that documentation will be installed to:

    doxygen_install_dir = join_paths(get_option('datadir'), 'doc',
                                     '@0@-@1@'.format(meson.project_name(),
                                                      as_version))

Using default values, that'd be: /usr/local/share/doc/v4l-utils-1.20.0/

Hopefully, there will be a doxygen module for meson at some point in the future.

Anyway, let me know if you have any comments.

Regards,
Ariel

I changed the code above to omit the version and now I have working 
Debian packages. I need to test the packages on a real Linux Desktop but 
that will have to wait until I can re-enter our offices.

Note that you can also use 'some' / 'path' instead of
join_paths('some', 'path'). AFAIK '/' works fine in Windows paths too.

Sounds good, I'll do that and reuse those variables whenever possible.

sync-with-kernel is a few fragments of shell that live in various parts
of the tree (Makefiles). It's just static shell, the build system doesn't
need to do any substitions.

I think sync-with-kernel doesn't really belong in the build system; This
can be moved into its own shell script.

Nice! This will really help when I'm testing on the rpi.

Yup, meson allows really simple and fast cross builds.

My colleague Stéphane has blogged [1] about this
recently.
