[Message part 1 (text/plain, inline)]

Hello,

The attached patch adds MuseScore. It builds and lint doesn't complain.

I used glib-or-gtk-build-system because, somewhere in the Makefile,
there's a call to `gtk-update-icon-cache'. However, since that command
cannot be found during the build process, I skip it with
UPDATE_CACHE=FALSE. So, should I leave the package as-is, or add
a "gtk+" input, or simply downgrade to gnu-build-system?

Also, the description is a bit verbose. It is an excerpt from
Wikipedia's introduction about the software. Debian's is much terser.
FSF directory's is out of date. WDYT?

Regards,

Since it uses Qt, perhaps we’d better use ‘gnu-build-system’ (or
‘cmake-build-system’?) no?  Would we lose something?

FWIW I trimmed the description a bit and moved ‘cmake’ to
‘native-inputs’.  Also, a couple of #:use-module were missing.

Hello,

cmake-build-system is a path I already walked. Using cmake is
insufficient to build the package, as it fails during the install phase.

IIUC, the Makefile is a wrapper that calls the cmake command, which, in
turn, generates a new make target that the initial make call can
process... The new target is responsible for, at the very least,
generating the translation files.

About gnu-build-system, I don't know if we loose something. It builds
with it. I can run the application. I thought that calling
gtk-update-icon-cache was somehow a clue that glib-or-gtk-build-system
would be needed, but I was wrong, if I interpret correctly your
question.

The updated patch uses gnu-build-system.

> FWIW I trimmed the description a bit

OK.

Maybe the linter could suggest it. It already told me that "qttools"
input should be moved there, but didn't complain about "cmake".

> Also, a couple of #:use-module were missing.

Oops. It probably happened when I moved the package definition from my
incubator to music.scm.

About the bundled freetype library: it is skipped per the cmake option.
Should we also delete it from source in a snippet or is it fine as-is?

Regards,

Good idea, I’ve added “cmake” to the list.

It’s always safer to remove it in a snippet.

I started doing that and then noticed that removing all of thirdparty/
won’t cut it.  Yet there’s quite a lot of stuff in that directory, so it
would be good to make sure we use as little as possible of this bundled
code:

$ ls /tmp/guix-build-musescore-2.1.0.drv-0/MuseScore-2.1.0/thirdparty/
beatroot  diff	intervaltree  kQOAuth  ofqf  portmidi  qzip  rtf2html  singleapp  xmlstream

For example, we could add portmidi as an input.

Could you take a look?

Thanks!

Ludo’.

It's even more wonderful when you realize that at 3am.

Fair enough.

The attached update includes the following changes:

  - un-bundle OpenSSL. Since it doesn't prevent compilation, do not even
    include ours, much like what Debian does.

  - remove unused portmidi from "thirdparty", per the following snippet
    in CMakeLists.txt

      # Disable components not supported on Linux/BSD
      if (NOT APPLE AND NOT MINGW)
             set(NIX_NOT_AVAIL "Not available on Linux/BSD")
             option(BUILD_PORTMIDI "PortMidi disabled on Linux. (It uses ALSA but it's better to use ALSA directly)" OFF)
      endif (NOT APPLE AND NOT MINGW)

  - un-bundle freetype, remove it from the "thirdparty" directory.

  - add "gtk+-bin" as inuput so that we can run `gtk-update-icon-cache'
    (still not sure this is really needed).

WDYT?

Regards,

Note that there’s still bundled software under thirdparty/ (those I
listed above), but apparently we have no existing packages for these.
So let’s assume it’s OK to have them for now, but we may have to revisit
that and actually remove them later on.

Thank you!

Ludo’.

I know, but it may be trickier than in sounds. For the record, some
software, "rtf2html" for example, seems to be modified for MuseScore. It
could be difficult to find a drop-in replacement.
