dh_makeshlibs - Linux
Overview
dh_makeshlibs is a command used in Debian packaging to generate shared libraries (.so) from static libraries (.a). It is used to prepare a Debian package for building and installing shared libraries, ensuring compatibility across different architectures and distributions.
Syntax
dh_makeshlibs [OPTIONS] [FILES...]
Options/Flags
- -a, –all: Process all available libraries in the package.
- -e, –exclude-regex=PATTERN: Exclude libraries matching the given regular expression from processing.
- -p, –patterns=PATTERN: Only process libraries matching the given comma-separated pattern.
- -i, –ignore-missing: Ignore missing files or dependencies and continue processing.
- -P, –preserve: Preserve existing .so files during processing.
- -V, –verbose: Print detailed messages about the processing.
- –help: Display help information and exit.
- –version: Display version information and exit.
Examples
Simple usage: Process all libraries in the package:
dh_makeshlibs
Exclude libraries: Ignore libraries whose names start with "libz":
dh_makeshlibs --exclude-regex="^libz"
Process specific libraries: Only process libraries matching the pattern "libfoo":
dh_makeshlibs --patterns="libfoo"
Preserve existing .so files:
dh_makeshlibs --preserve
Common Issues
- Missing dependencies: Ensure that all necessary dependencies are installed before running dh_makeshlibs.
- Incorrect patterns: Check that the specified patterns correctly match the desired libraries.
- Failed compilation: If libraries fail to compile, verify that the necessary compilers and libraries are available.
Integration
dh_makeshlibs is typically used in a Debian package build process:
- Create a "debian/rules" file that calls dh_makeshlibs in the "override_dh_installinit" target.
- Add a "debian/shlibs" file to specify the shared libraries to be installed.
- Build the package using
dpkg-buildpackage -us -uc
.
