dh_shlibdeps - Linux
Overview
dh_shlibdeps generates dependency information for shared libraries, making it easier to package them for distribution. It reads object files and creates a Depends:
line for a Debian package’s control
file, ensuring that the package includes all necessary dependencies.
Syntax
dh_shlibdeps [-e|--exclude=PACKAGES...] [-x|--extra=PACKAGES...] [-a|--arch=ARCHITECTURE...] [-- DEBIAN_FILE]
Options/Flags
- -e, –exclude=PACKAGES…: Exclude packages from dependency resolution.
- -x, –extra=PACKAGES…: Include extra packages in dependency resolution.
- -a, –arch=ARCHITECTURE…: Specify the target architecture(s) for dependency resolution.
- —: Pass options directly to
ldd
.
Examples
Simple Usage:
dh_shlibdeps hello -- hello.deb
Custom Architecture:
dh_shlibdeps --arch=armhf,arm64 hello -- hello.deb
Common Issues
- Missing Dependencies: Ensure that all relevant packages are included in
--extra
or that they are already installed on the system. - Conflicting Architectures: Check that the target architecture specified in
--arch
matches the architecture of the system where the package will be installed.
Integration
- Build Dependencies: Integrate dh_shlibdeps into build processes to automatically generate dependency information for packaged shared libraries.
- Package Maintenance: Use dh_shlibdeps to update dependency information during package updates or when new dependencies are introduced.
