# If either revision or age are omitted, they default to 0. Also note that age
|
# The following explanation may help to understand the above rules a bit
|

# must be less than or equal to the current interface number.
|
# better: consider that there are three possible kinds of reactions from
|

|
# users of your library to changes in a shared library:
|

#
|
||||||
# Here are a set of rules to help you update your library version information:
|
# 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.
|
||||||
#
|
#
|
||||||
# 1. Start with version information of `0:0:0' for each libtool library.
|
# 2. Programs using the previous version may use the new version as drop-in
|
||||||
# 2. Update the version information only immediately before a public release
|
# replacement, but programs using the new version may use APIs not
|
||||||
# of your software. More frequent updates are unnecessary, and only
|
# present in the previous one. In other words, a program linking against
|
||||||
# guarantee that the current interface number gets larger faster.
|
# the new version may fail with “unresolved symbols” if linking against
|
||||||
# 3. If the library source code has changed at all since the last update, then
|
# the old version at runtime: set revision to 0, bump current and age.
|
||||||
# increment revision (`c:r:a' becomes `c:r+1:a').

|
||||||
# update, increment current, and set revision to 0.
|
# the new version. Bump current, set revision and age to 0.
|
||||||
# 5. If any interfaces have been added since the last public release, then

# increment age.
|
|
