dnl CURRENT and AGE describe the binary compatibility interval of a |

dnl dynamic library. |

dnl See also http://www.gnu.org/software/libtool/manual.html#Interfaces |

dnl |
|
dnl The name of the library will be libisofs.so.$CURRENT-$AGE.$AGE.$REV |
|
dnl In the terminology of this file: |
|
dnl CURRENT = LT_CURRENT |
|
dnl REV = LT_REVISION |
|
dnl AGE = LT_AGE |
|
dnl |
|
dnl LT_CURRENT, LT_REVISION and LT_AGE get set directly now. |
|
dnl |
|
dnl SONAME of the emerging library is LT_CURRENT - LT_AGE. |
|
dnl The linker will do no finer checks. If SONAME matches, then the couple |
|
dnl starts. |
|
dnl |
|
dnl Therefore a run time check is provided by libisofs function |
|
dnl iso_lib_version(). It returns the major, minor and micro revision of the |
|
dnl library. This means LIBISOFS_*_VERSION kept its second job which does not |
|
dnl comply to the usual ways of configure.ac . I.e. now *officially* this is |
|
dnl the source code release version as announced to the public. It has no |
|
dnl connection to SONAME or libtool version numbering. |
|
dnl It rather feeds the API function iso_lib_version(). |
