dnl Note by ts A71207:
|

dnl
|

dnl if MAJOR or MINOR version changes, be sure to change AC_INIT above to match
|
||||
dnl BURN_MICRO_VERSION is _not_ the third component Z of libburn-X.Y.Z
|
||||
dnl but an eternal counter which leads to SONAME. This misunderstanding
|
||||
dnl caused a messed up sequence of SONAMEs.
|
||||
dnl
|
||||
dnl SONAME and AGE describe the binary compatibility interval of a
|
||||
dnl dynamic library. See also http://www.gnu.org/software/libtool/manual.html
|
||||
dnl
|
||||
dnl The name of the library will be libburn.so.$SONAME.$REV.$AGE
|
||||
dnl In the terminology of this file:
|
||||
dnl SONAME= LT_CURRENT
|
||||
dnl REV = LT_REVISION
|
||||
dnle AGE = LT_AGE
|
||||
dnl
|
||||
dnl In the past the following SONAMEs of libburn have been released.
|
||||
dnl All with AGE=0.
|
||||
dnl 0.2.2 = 2 , 0.2.3 = 3 , 0.2.6 = 6
|
||||
dnl 0.3.0 = 0 , 0.3.2 = 2 , 0.3.4 = 4 . 0.3.6 = 6 , 0.3.8 = 4
|
||||
dnl 0.4.0 = 4
|
||||
dnl
|
||||
dnl Beginning with libburn-0.4.1 a rectified counting was introduced as
|
||||
dnl SONAME=10, REV=1, AGE=6
|
||||
dnl This rectification declared the current version
|
||||
dnl to be binary compatible down to libburn-0.3.4.
|
||||
dnl Real backward compatibility is given down to libburn-0.3.2.
|
||||
dnl Beware of libburn-0.2.6 which had SONAME=6.
|
||||
dnl
|
||||
dnl SONAME=10, REV=0, AGE=6 would be appropriate for libburn-0.4.0
|
||||
dnl but was not issued, regreattably.
|
||||
dnl
|
||||
dnl If libburn-0.4.0 gets patched, its SONAME will become 10, AGE 6, and
|
||||
dnl REV will be set to one higher than the highest REV of SONAME 10.
|
||||
dnl If libburn-0.4.1 is still on SONAME 10 then its REV gets set one higher
|
||||
dnl than that.
|
||||
dnl As soon as 0.4.1 becomes upwardly incompatible, it shall become 11,0,7.
|
||||
dnl From then on it counts REV independently of libburn-0.4.0.
|
||||
dnl Whether 0.4.1 alters independent REV at all, is not decided yet.
|
||||
dnl It may well stay 0 until a release version joins SONAME 11.
|
||||
dnl
|
||||
dnl Under the preconditions
|
||||
dnl SONAME= $BURN_MICRO_VERSION - $BURN_INTERFACE_AGE
|
||||
dnl REV= $BURN_INTERFACE_AGE
|
||||
dnl AGE= $BURN_BINARY_AGE
|
||||
dnl the following old instructions were reasonable. Their drawback
|
||||
dnl is that they cause large jumps in SONAME, when BURN_INTERFACE_AGE gets
|
||||
dnl reset to 0 from a high value. So this is outdated now:
