Programs using the previous version may use the new version as drop-in 19# replacement, and programs using the new version can also work with the 20# previous one. In other words, no recompiling nor relinking is needed. 21# In this case, bump revision only, don't touch current nor age. 22# 23# 2. Programs using the previous version may use the new version as drop-in 24# replacement, but programs using the new version may use APIs not 25# present in the previous one. In other words, a program linking against 26# the new version may fail with “unresolved symbols” if linking against 27# the old version at runtime: set revision to 0, bump current and age. 28# 29# 3. Programs may need to be changed, recompiled, relinked in order to use 30# the new version. Bump current, set revision and age to 0. 31 32m4_define([libnl_lt_current], [226]) 33m4_define([libnl_lt_revision], [0]) 34m4_define([libnl_lt_age], [26]) 35 36m4_define([libnl_version], 37 [libnl_major_version.libnl_minor_version.libnl_micro_version]) 38 39AC_INIT(libnl, [libnl_version], [], [], [http://www.infradead.org/~tgr/libnl/]) 40AC_CONFIG_HEADERS([lib/defs.h]) 41AC_CONFIG_AUX_DIR([build-aux]) 42AC_CONFIG_MACRO_DIR([m4]) 43AM_INIT_AUTOMAKE([-Wall foreign subdir-objects]) 44m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES(yes)], []) 45m4_ifdef([AM_PROG_AR], [AM_PROG_AR]) 46 47MAJ_VERSION=libnl_major_version 48AC_SUBST(MAJ_VERSION) 49MIN_VERSION=libnl_minor_version 50AC_SUBST(MIN_VERSION) 51MIC_VERSION=libnl_micro_version 52AC_SUBST(MIC_VERSION) 53LIBNL_GIT_SHA=libnl_git_sha 54LIBNL_VERSION=libnl_version 55AC_SUBST(LIBNL_VERSION) 56 57LT_CURRENT=libnl_lt_current 58AC_SUBST(LT_CURRENT) 59LT_REVISION=libnl_lt_revision 60AC_SUBST(LT_REVISION) 61LT_AGE=libnl_lt_age 62AC_SUBST(LT_AGE) 63 64AC_PROG_CC 65AM_PROG_CC_C_O 66AC_PROG_INSTALL 67AM_PROG_LIBTOOL 68AC_PROG_MKDIR_P 69AC_CHECK_PROGS(FLEX, 'flex') 70AC_CHECK_PROGS(YACC, 'bison -y') 71 72AC_C_CONST 73AC_C_INLINE 74 75PKG_CHECK_MODULES([CHECK], [check >= 0.9.0], 76 [has_check="yes"], 77 [AC_MSG_WARN([*** Disabling building of unit tests]) 78 has_check="no"]) 79AM_CONDITIONAL(WITH_CHECK, [test "$has_check" = 'yes']) 80 81AC_ARG_WITH([pkgconfigdir], AS_HELP_STRING([--with-pkgconfigdir=PATH], 82 [Path to the pkgconfig directory [[LIBDIR/pkgconfig]]]), 83 [pkgconfigdir="$withval"], [pkgconfigdir='${libdir}/pkgconfig']) 84AC_SUBST([pkgconfigdir]) 85 86AC_ARG_ENABLE([cli], 87 AS_HELP_STRING([--enable-cli=yes|no|no-inst|bin|sbin], [Whether to build command line interface utils.
