The library linter is a Snapcraft linter that is used to verify whether any ELF file dependencies, typically libraries, are missing from a snap. It also verifies if any libraries are included in a snap but are not used.
See Disabling linters for details on how to stop this linter running.
If a snapped application depends on libraries neither provided by the base system, nor included as a dependency, the snap package may execute in an incorrect or unpredictable way. The library linter issues a warning if a missing dependency is detected.
Snap package size can be reduced by removing extra libraries that are not used by the applications in the snap. The library linter issues a warning if unused libraries are detected.
The library linter will issue a warning if:
The example below shows two missing libraries (libcaca
and libslang
) and one unused library (libpng16
).
Running linter: library
Lint warnings:
- library: my-app: missing dependency 'libcaca.so.0'.
- library: my-app: missing dependency 'libslang.so.2'.
- library: libpng16.so.16: unused library 'usr/lib/x86_64-linux-gnu/libpng16.so.16.37.0'.
To address library linter issues, packages containing any missing libraries need to be added to the list of stage-packages
. Unused libraries can be removed from stage-packages
. See Build and staging dependencies for further details.
