# The following explanation may help to understand the above rules a bit
|
|
# better: consider that there are three possible kinds of reactions from
|
|
# users of your library to changes in a shared library:
|
|
#
|
|
# 1. Programs using the previous version may use the new version as drop-in
|
|
# replacement, and programs using the new version can also work with the
|
|
# previous one. In other words, no recompiling nor relinking is needed.
|
|
# In this case, bump revision only, don't touch current nor age.
|
|
#
|
|
# 2. Programs using the previous version may use the new version as drop-in
|
|
# replacement, but programs using the new version may use APIs not
|
|
# present in the previous one. In other words, a program linking against
|
|
# the new version may fail with “unresolved symbols” if linking against
|
|
# the old version at runtime: set revision to 0, bump current and age.
|
|
#
|
|
# 3. Programs may need to be changed, recompiled, relinked in order to use
|
|
# the new version. Bump current, set revision and age to 0.
