CARES_VERSION_INFO="7:1:5" |
|
dnl This flag accepts an argument of the form current[:revision[:age]]. So, |
|
dnl passing -version-info 3:12:1 sets current to 3, revision to 12, and age to |
|
dnl 1. |
|
dnl |
|
dnl If either revision or age are omitted, they default to 0. Also note that age |
|
dnl must be less than or equal to the current interface number. |
|
dnl |
|
dnl Here are a set of rules to help you update your library version information: |
|
dnl |
|
dnl 1.Start with version information of 0:0:0 for each libtool library. |
|
dnl |
|
dnl 2.Update the version information only immediately before a public release of |
|
dnl your software. More frequent updates are unnecessary, and only guarantee |
|
dnl that the current interface number gets larger faster. |
|
dnl |
|
dnl 3.If the library source code has changed at all since the last update, then |
|
dnl increment revision (c:r+1:a) |
|
dnl |
|
dnl 4.If any interfaces have been added, removed, or changed since the last |
|
dnl update, increment current, and set revision to 0. (c+1:r=0:a) |
|
dnl |
|
dnl 5.If any interfaces have been added since the last public release, then |
|
dnl increment age. (c:r:a+1) |
|
dnl |
|
dnl 6.If any interfaces have been removed since the last public release, then |
|
dnl set age to 0. (c:r:a=0) |
