ABI/API changes incompatibly from release to release, but
libQuantLib.so.{0,0.0.0} keep its name?
Until you convince upstream to do things properly you'll have to add
Replaces: libquantlib-1.1, libquantlib-1.0.0
Breaks: libquantlib-1.1, libquantlib-1.0.0
to libquantlib-X.Y
I see there is already
Replaces: libquantlib0
Conflicts: libquantlib0
If you add
Provides: libquantlib0
you can stop adding future package names to the above list as it will
ensure only one package providing the virtual package libquantlib0 can
be installed at a time.
The short Description: seems to be swapped, too:
libquantlib-1.2 - Quantitative Finance Library -- development package
libquantlib0-dev - Quantitative Finance Library -- library package
quantlib-examples - Quantitative Finance Library -- example binaries
