Programs using the previous version may use the new version as drop-in # replacement, and programs using the new version can also work with the # previous one. In other words, no recompiling nor relinking is needed. # In this case, bump revision only, don't touch current nor age. # # 2. Programs using the previous version may use the new version as drop-in # replacement, but programs using the new version may use APIs not # present in the previous one. In other words, a program linking against # the new version may fail with “unresolved symbols” if linking against # the old version at runtime: set revision to 0, bump current and age. # # 3. Programs may need to be changed, recompiled, relinked in order to use # the new version. Bump current, set revision and age to 0. m4_define([libnl_lt_current], [226]) m4_define([libnl_lt_revision], [0]) m4_define([libnl_lt_age], [26]) m4_define([libnl_version], [libnl_major_version.libnl_minor_version.libnl_micro_version]) AC_INIT(libnl, [libnl_version], [], [], [http://www.infradead.org/~tgr/libnl/]) AC_CONFIG_HEADERS([lib/defs.h]) AC_CONFIG_AUX_DIR([build-aux]) AC_CONFIG_MACRO_DIR([m4]) AM_INIT_AUTOMAKE([-Wall foreign subdir-objects]) m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES(yes)], []) m4_ifdef([AM_PROG_AR], [AM_PROG_AR]) MAJ_VERSION=libnl_major_version AC_SUBST(MAJ_VERSION) MIN_VERSION=libnl_minor_version AC_SUBST(MIN_VERSION) MIC_VERSION=libnl_micro_version AC_SUBST(MIC_VERSION) LIBNL_GIT_SHA=libnl_git_sha LIBNL_VERSION=libnl_version AC_SUBST(LIBNL_VERSION) LT_CURRENT=libnl_lt_current AC_SUBST(LT_CURRENT) LT_REVISION=libnl_lt_revision AC_SUBST(LT_REVISION) LT_AGE=libnl_lt_age AC_SUBST(LT_AGE) AC_PROG_CC AM_PROG_CC_C_O AC_PROG_INSTALL AM_PROG_LIBTOOL AC_PROG_MKDIR_P AC_CHECK_PROGS(FLEX, 'flex') AC_CHECK_PROGS(YACC, 'bison -y') AC_C_CONST AC_C_INLINE PKG_CHECK_MODULES([CHECK], [check >= 0.9.0], [has_check="yes"], [AC_MSG_WARN([*** Disabling building of unit tests]) has_check="no"]) AM_CONDITIONAL(WITH_CHECK, [test "$has_check" = 'yes']) AC_ARG_WITH([pkgconfigdir], AS_HELP_STRING([--with-pkgconfigdir=PATH], [Path to the pkgconfig directory [[LIBDIR/pkgconfig]]]), [pkgconfigdir="$withval"], [pkgconfigdir='${libdir}/pkgconfig']) AC_SUBST([pkgconfigdir]) AC_ARG_ENABLE([cli], AS_HELP_STRING([--enable-cli=yes|no|no-inst|bin|sbin], [Whether to build command line interface utils.
