dnl Notes by ts A71207 - A80126 :
|
|
dnl
|
|
dnl Regrettably the meaning of the various version types was misunderstood
|
|
dnl before version 0.4.1.
|
|
dnl
|
|
dnl In the past MAJOR.MINOR.MICRO versions led to the following SONAME numbers:
|
|
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 = 0 (also released as SONAME 4)
|
|
dnl
|
|
dnl Meanwhile the following schemes are maintained in parallel:
|
|
dnl
|
|
dnl BURN_MAJOR_VERSION , BURN_MINOR_VERSION , BURN_MICRO_VERSION
|
|
dnl are three small non-negative integers which describe the evolution
|
|
dnl steps of the library.
|
|
dnl Older applications are able to use younger libraries over
|
|
dnl quite a long range of such steps. Some day, nevertheless,
|
|
dnl compatibility might get terminated, after due notice.
|
|
dnl
|
|
dnl SONAME (libburn.so.4)
|
|
dnl is a small positive integer which marks a family of compatible
|
|
dnl evolution steps. Libraries with a particular SONAME allow a binary
|
|
dnl with the same SONAME to start up. Any further compatibility check is to
|
|
dnl be done by own runtime means. Especially *_version() calls in the API
|
|
dnl which return BURN_MAJOR_VERSION, BURN_MINOR_VERSION, BURN_MICRO_VERSION.
|
|
dnl See below.
|
|
dnl
|
|
dnl CURRENT, AGE, REVISION
|
|
dnl are three integers used by libtool. CURRENT is positive, the others
|
|
dnl non-negative. The use at runtime is not known yet. But libtool computes
|
|
dnl at build time SONAME = CURRENT - AGE.
|
|
dnl So this is a superspace of the SONAME version space. To avoid
|
|
dnl ill SONAME, the value of CURRENT must be larger than AGE.
|
|
dnl See also http://www.gnu.org/software/libtool/manual.html#Interfaces
|
|
dnl
|
|
dnl The name of the dynamic library will be libburn.so.$SONAME.$AGE.$REV .
|
|
dnl In the terminology of this file:
|
|
dnl CURRENT = LT_CURRENT
|
|
dnl AGE = LT_AGE
|
|
dnl REVISION= LT_REVISION
|
|
dnl
|
|
dnl Beginning with libburn-0.4.1 a rectified counting was introduced as
|
|
dnl CURRENT=10, REVISION=1, AGE=6
|
|
dnl This rectification declared that version to be binary compatible up
|
|
dnl from libburn-0.3.4.
|
|
dnl Real compatibility was given since libburn-0.3.2.
|
|
dnl Beware of libburn-0.2.6 which had SONAME=6 and is not binary compatible.
|
|
dnl Applications for libburn-0.2 to libburn-0.3.1 need recompilation but no
|
|
dnl source code changes.
|
|
dnl
|
|
dnl Neatly versioned stable releases meanwhile:
|
|
dnl 0.4.2 = libburn.so.4.7.0
|
|
dnl 0.4.4 = libburn.so.4.9.0
|
|
dnl 0.4.6 = libburn.so.4.11.0
|
|
dnl 0.4.8 = libburn.so.4.13.0
|
|
dnl 0.5.0 = libburn.so.4.15.0
|
|
dnl 0.5.2 = libburn.so.4.17.0
|
|
dnl 0.5.4 = libburn.so.4.19.0
|
|
dnl
|
|
dnl So LT_CURRENT, LT_REVISION and LT_AGE get set directly here.
|
|
dnl SONAME of the emerging library is LT_CURRENT - LT_AGE.
|
|
dnl The linker will do no finer checks. Especially no age range check for
|
|
dnl the application binary. If SONAME matches, then the couple starts.
|
|
dnl
|
|
dnl Therefore at run time info is provided by libburn function burn_version().
|
|
dnl It returns the major, minor and micro revision of the library.
|
|
dnl Before using any API feature, a program should check for age.
|
|
dnl
|
|
dnl The variables BURN_*_VERSION are mere copies for informing libtool.
|
|
dnl The true values which get issued and should be compared are macros
|
|
dnl defined in libburn/libburn.h .
|
|
dnl
|
|
dnl Normally one can allow a program to run with a library which passed the
|
|
dnl linker SONAME test and which is not older than the library it was
|
|
dnl developed for. Library2 is younger than library1 if:
|
|
dnl major2>major1 || (major2==major1 &&
|
|
dnl (minor2>minor1 || (minor2==minor1 && micro2 > micro1)))
|
|
dnl
|
|
dnl If BURN_*_VERSION changes, be sure to change AC_INIT above to match.
