Especially no age range check for dnl the cdrskin binary. If SONAME matches, then the couple 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 conection to SONAME or libtool version numbering. dnl It rather feeds the API function iso_lib_version(). dnl dnl If LIBISOFS_*_VERSION changes, be sure to change AC_INIT above to match. dnl LIBISOFS_MAJOR_VERSION=0 LIBISOFS_MINOR_VERSION=6 LIBISOFS_MICRO_VERSION=3 LIBISOFS_VERSION=$LIBISOFS_MAJOR_VERSION.$LIBISOFS_MINOR_VERSION.$LIBISOFS_MICRO_VERSION AC_SUBST(LIBISOFS_MAJOR_VERSION) AC_SUBST(LIBISOFS_MINOR_VERSION) AC_SUBST(LIBISOFS_MICRO_VERSION) AC_SUBST(LIBISOFS_VERSION) dnl Libtool versioning LT_RELEASE=$LIBISOFS_MAJOR_VERSION.$LIBISOFS_MINOR_VERSION # SONAME = 6 - 0 = 6 .
