PKGKDE-SYMBOLSHELPER(1) Debian KDE symbols helper PKGKDE-SYMBOLSHELPER(1)

NAME

pkgkde-symbolshelper - a tool to help simplify managing C++ symbols files for the KDE project.

SYNOPSIS

pkgkde-symbolshelper create | patch | batchpatch | rewrite

DESCRIPTION

pkgkde-symbolshelper provides helps to automate the process of managing your deb-symbols(5) files.

There are four commands, create, patch, batchpatch, and rewrite.

CREATING SYMBOLS FILE

To create the symbols file for a library package libfoo1 whose version is 1.7

pkgkde-gensymbols -plibfoo1 -v1.7 -Osymbols.amd64 -edebian/libfoo1/usr/lib/libfoo.so.1
pkgkde-symbolshelper create -o debian/libfoo1.symbols -v 1.7 symbols.amd64


The above commands should be invoked from the top level directory of your package's source after having built the package before cleaning, so that debian/libfoo1/usr/lib/libfoo.so.1 exists).

"symbols.amd64" is the filename of the intermediate symbols file that will be generated by pkgkde-gensymbols. This filename must be in the format "name.architecture" or "name_architecture" where "architecture" is the cpu architecture on which you have built this package.

UPDATING A SYMBOLS FILE FOR A NEW LIBRARY VERSION

After building a new version of the library (for instance 1.8 of our libfoo1 library from above), symbols may have been added or removed, and in both cases one must check and update the symbols file. During the build, a diff between the current symbols file and the one based on the current built library will printed in the output. pkgkde-symbolshelper can read the build log to find this diff, to save the build log one may want to do:

dpkg-buildpackage | tee buildlog
pkgkde-symbolshelper patch -p libfoo1 -v 1.8 < buildlog


UPDATING MULTIPLE SYMBOLS FILES AT ONCE

For source packages that provide multiple binary library packages, it is useful to have a method to patch all the symbol files at once, pkgkde-symbolshelper offers a way to do this using the batchpatch command. For example:

pkgkde-symbolshelper batchpatch -v 1.8 < buildlog


batchpatch can also be of use when one wants to update symbol files for multiple architectures at once. There is an additional command pkgkde-getbuildlogs that will download the build logs for multiple architectures from Debian's build servers.


pkgkde-getbuildlogs
pkgkde-symbolshelper batchpatch -v 1.8 foo_unstable_logs/foo_1.8-1*.build
