dnl Notes about version numbers and .so numbers: |
|
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 On Linux the name of the dynamic library will be |
|
dnl 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 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. |
