troubles with symbols files on a Qt extension library

[Thomas PIERSON]

Hello Qt/Kde maintainers,

I maintain the LibQxt package which is a Qt extension library. LibQxt
source package provides multiple binary packages (core and modules).
I want to improve the package quality using symbols files but I have
some troubles and I need some help.

I used pkg-kde-tools to create symbols files for each core and modules
of LibQxt. I followed the pkg-kde.alioth documentation page [1].
After that, I built the package without any errors. But when the package
was uploaded and built on other architectures the build fail because of
differences between symbols files :

dpkg-gensymbols: warning: some new symbols appeared in the symbols file:
see diff output below
dpkg-gensymbols: warning: some symbols or patterns disappeared in the
symbols file: see diff output below
dpkg-gensymbols: warning: debian/libqxt-core0/DEBIAN/symbols doesn't
match completely debian/libqxt-core0.symbols
[ ...diff below...]

So, I used this command to patch each libraries components :

pkgkde-symbolshelper batchpatch -v 1.8 buildlog

I repeated this for each architectures and I obtained symbols files
which was "confirmed" for all architectures.

After a new upload, the build process on some architectures failed again
cause of new differences! (see all build logs here [2])
I also remark that some builds failed for the same reasons if I build on
stable instead of unstable repository.

Finally, I don't know why the symbols are different according to
architectures and repositories. Maybe I simply can't use symbol files
with this library! Maybe someone have an idea about this situation?

Thanks for your help.

Best regards,
Thomas Pierson
