| 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 |
| 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. |
