Create snap package
- Install snapcraft to your Ubuntu machine with sudo apt install snapcraft
- Create snap subdirectory in your project
- Execute snapcraft init to create snap/snapcraft.yaml initial file
- Example file:
name: myapp version: '1.0.0' summary: Short description of package. description: | Some more detailed multi-line description. confinement: devmode base: core20 grade: devel parts: myapp: plugin: nil source: . source-type: local build-packages: - fpc - lazarus - lcl - lcl-utils stage-packages: # Autodetected dependencies - libatk1.0-0 - libcairo2 - libdatrie1 - libfontconfig1 - libfreetype6 - libfribidi0 - libgdk-pixbuf2.0-0 - libgraphite2-3 - libgtk2.0-0 - libharfbuzz0b - libpango-1.0-0 - libpangocairo-1.0-0 - libpangoft2-1.0-0 - libpixman-1-0 - libpng16-16 - libthai0 - libx11-6 - libxau6 - libxcb-render0 - libxcb-shm0 - libxcb1 - libxcomposite1 - libxcursor1 - libxdamage1 - libxdmcp6 - libxext6 - libxfixes3 - libxi6 - libxinerama1 - libxrandr2 - libxrender1 override-build: | lazbuild --build-mode=Release myapp.lpi ROOT=/root/parts/myapp/install install -d -m 755 $ROOT/usr/share/myapp install -s -m 755 myapp $ROOT/usr/share/myapp install -d -m 755 $ROOT/usr/share/applications install -m 755 Install/deb/myapp.desktop $ROOT/usr/share/applications stage: - etc - lib - usr - usr/share/myapp - usr/share/applications/myapp.desktop apps: myapp: command: usr/share/myapp/myapp desktop: usr/share/applications/myapp.desktop plugs: - home - desktop
- Build snap using snapcraft command
- Install newly created snap with sudo snap install --dangerous --devmode myapp_1.0.0_amd64.snap
Snap supports sound through plugs pulseaudio and audio-playback.
apps: myapp: plugs: - pulseaudio - audio-playback
You can play wav and mp3 files from command line using play command. See Play Sound Multiplatform. Then you also need to add stage-packages to myapp part:
parts: myapp: stage-packages: - sox - libsox-fmt-mp3 - libsox-fmt-pulse - libpulse0
snapcraft.yaml file in non-standard subdirectory
Snapcraft normally expect snapcraft.yaml file in snap directory. If your project has packaging for multiple other packaging formats, then you need to use build workaround script. Such shell script can put into directory like myapp/install/snap/local as build.sh file.
#!/bin/bash ln -s install/snap ../../../snap pushd ../../.. snapcraft popd rm ../../../snap
