Pulseeffects: Missing pulseeffects.desktop file

[muzena]

@mikhailnov
There is missing pulseeffects.desktop in /usr/share/applications deb file

And won't start from terminal.
I get this error:
$ pulseeffects
Traceback (most recent call last):
File "/usr/bin/pulseeffects", line 6, in

ValueError: Namespace GstInsertBin not available

The error ValueError: Namespace GstInsertBin not available is happening because you do not have gst-plugins-bad. It may not have been included as dependency in the deb file

If you are looking for the desktop entry file it is named com.github.wwmm.pulseeffects.desktop, as recommended in the desktop entry specification. A simple way is queering for files owned by a package:

dpkg-query -L pulseeffects | grep \.desktop

[mikhailnov]

@wwmm it is a dependency:

python3, libgtk-3-0 (>= 3.18), python3-gi-cairo, python3-cairo, gstreamer1.0-plugins-bad (>= 1.12), gstreamer1.0-plugins-good (>= 1.12), swh-plugins, python3-scipy (>= 0.18), python3-gst-1.0

@muzena please post an output of
# env LANG=c apt -f install
to make sure that all dependencies have been installed.

I see that .desktop and glib schemas are missing, will try to fix it, I missed it because I first installed PulseEffects from source and did not do sudo ninja uninstall before testing the package.

[mikhailnov]

@wwmm please assign me to this issue if possible

[wwmm]

For some reason it only lists me and muzena as possible users

[mikhailnov]

Wow, I've commented out export DH_ALWAYS_EXCLUDE=.git from debian/rules and now .desktop and other files do not mysteriously disappear when building the package
I have no idea why this works)

[muzena]

@wwmm @mikhailnov
I solved problem by installing gir1.2-gst-plugins-bad-1.0 package
You need add this to install dependencies in debian control file.

When I try to build pulseeffects_*.deb from source on this way:
git clone https://github.com/wwmm/pulseeffects.git
cd pulseeffects
mk-build-deps --install debian/control
debuild -I

I get this error:

[mikhailnov]

gir1.2-gst-plugins-base-1.0 are not needed?

[mikhailnov]

Do I understand correctly that gstreamer1.0-plugins-bad (>= 1.12) is a dependency for running PulseEffects and gir1.2-gst-plugins-base-1.0 are needed only to build it?

[mikhailnov]

to be more exact, libgstreamer-plugins-bad1.0-dev

[mikhailnov]

it seems that gir1.2-gst-plugins-bad-1.0 is needed not only while building

[wwmm]

I don't know. I do not understand why Debian distro split the libraries in so many packages. Here you can see the dependencies in the package I maintain for Arch Linux https://aur.archlinux.org/packages/pulseeffects/. Maybe it helps to figure out what is really needed in ubuntu

[mikhailnov]

I've commited the changes, now I will try to make a test on a very clean system to see if it works or not. What makes testing not so easy is that many of the dependencies are pulled bu other desktop packages

[mikhailnov]

Also it's possible to use https://gitlab.com/ole.tange/tangetools/blob/master/tracefile/tracefile to see all the files which are accessed but the results will probably be innaccurate

[AsavarTzeth]

The packages you require are quite clearly documented in the wiki.

I added those packages to the wiki page based on test results in a clean Ubuntu 17.10 virtual machine. I added that information as a response to a lot of users asking about Debian dependencies in issue threads.

Runtime dependencies:

libgtk-3-0 python3-gi python3-gi-cairo python3-numpy python3-scipy libgstreamer1.0-0 libgstreamer-plugins-good1.0-0 libgstreamer-plugins-bad1.0-0 python3-gst-1.0 swh-plugins

Build time dependencies and tools:

libgtk-3-dev python-gi-dev python3-cairo-dev libgstreamer1.0-dev libgstreamer-plugins-bad1.0-dev libpulse-dev git meson ninja-build pkg-config

Depending on how you fetch pulseeffects "git" might not be necessary.

As a rule, *-dev packages are only used during building. Although in this case its not actually used to build anything since it is python. It is instead used for dependency resolution, i.e. it is required in order for meson to be able to tell if dependencies are missing.

Sorry for spending everyone's time with not properly tested pull requests. I've tested this one and now everything should work.

@AsavarTzeth python3-numpy is a dependency of python3-scipy, so I did not add it
