Programs using the previous version may use the new version as drop-in 25# replacement, and programs using the new version can also work with the 26# previous one. In other words, no recompiling nor relinking is needed. 27# In this case, bump revision only, don't touch current nor age. 28# 29# 2. Programs using the previous version may use the new version as drop-in 30# replacement, but programs using the new version may use APIs not 31# present in the previous one. In other words, a program linking against 32# the new version may fail with “unresolved symbols” if linking against 33# the old version at runtime: set revision to 0, bump current and age. 34# 35# 3. Programs may need to be changed, recompiled, relinked in order to use 36# the new version. Bump current, set revision and age to 0. 37 38m4_define([libnl_lt_current], [220]) 39m4_define([libnl_lt_revision], [0]) 40m4_define([libnl_lt_age], [20]) 41 42m4_define([libnl_version], 43 [libnl_major_version.libnl_minor_version.libnl_micro_version]) 44 45AC_INIT(libnl, [libnl_version], [], [], [http://www.infradead.org/~tgr/libnl/]) 46AC_CONFIG_HEADERS([lib/defs.h]) 47AC_CONFIG_AUX_DIR([build-aux]) 48AC_CONFIG_MACRO_DIR([m4]) 49AM_INIT_AUTOMAKE([-Wall foreign subdir-objects]) 50m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES(yes)], []) 51m4_ifdef([AM_PROG_AR], [AM_PROG_AR]) 52 53MAJ_VERSION=libnl_major_version 54AC_SUBST(MAJ_VERSION) 55MIN_VERSION=libnl_minor_version 56AC_SUBST(MIN_VERSION) 57MIC_VERSION=libnl_micro_version 58AC_SUBST(MIC_VERSION) 59LIBNL_GIT_SHA=libnl_git_sha 60LIBNL_VERSION=libnl_version 61AC_SUBST(LIBNL_VERSION) 62 63LT_CURRENT=libnl_lt_current 64AC_SUBST(LT_CURRENT) 65LT_REVISION=libnl_lt_revision 66AC_SUBST(LT_REVISION) 67LT_AGE=libnl_lt_age 68AC_SUBST(LT_AGE) 69 70AC_PROG_CC 71AM_PROG_CC_C_O 72AC_PROG_INSTALL 73AM_PROG_LIBTOOL 74AC_PROG_MKDIR_P 75AC_CHECK_PROGS(FLEX, 'flex') 76AC_CHECK_PROGS(YACC, 'bison -y') 77 78AC_C_CONST 79AC_C_INLINE 80 81PKG_CHECK_MODULES([CHECK], [check >= 0.9.0], 82 [enable_unit_tests="yes"], 83 [AC_MSG_WARN([*** Disabling building of unit tests]) 84 enable_unit_tests="no"]) 85 86AM_CONDITIONAL([ENABLE_UNIT_TESTS], [test "$enable_unit_tests" = "yes"]) 87 88AC_ARG_WITH([pkgconfigdir], AS_HELP_STRING([--with-pkgconfigdir=PATH], 89 [Path to the pkgconfig directory [[LIBDIR/pkgconfig]]]), 90 [pkgconfigdir="$withval"], [pkgconfigdir='${libdir}/pkgconfig']) 91AC_SUBST([pkgconfigdir]) 92 93AC_ARG_ENABLE([cli], 94 AS_HELP_STRING([--disable-cli], [Do not build command line interface utils]), 95 [enable_cli="$enableval"], [enable_cli="yes"]) 96AM_CONDITIONAL([ENABLE_CLI], [test "$enable_cli" = "yes"]) 97 98AC_ARG_ENABLE([pthreads], 99 AS_HELP_STRING([--disable-pthreads], [Disable pthreads support]), 100 [enable_pthreads="$enableval"], [enable_pthreads="yes"]) 101AM_CONDITIONAL([DISABLE_PTHREADS], [test "$enable_pthreads" = "no"]) 102 103AC_ARG_ENABLE([debug], 104 AS_HELP_STRING([--disable-debug], [Do not include debugging statements]), 105 [enable_debug="$enableval"], [enable_debug="yes"]) 106AM_CONDITIONAL([ENABLE_DEBUG], [test "$enable_debug" = "no" ]) 107 108AC_CHECK_LIB([m], [pow], [], AC_MSG_ERROR([libm is required])) 109 110if test "x$enable_pthreads" = "xno"; then 111 AC_DEFINE([DISABLE_PTHREADS], [1], [Define to 1 to disable pthreads]) 112else 113 AC_CHECK_LIB([pthread], [pthread_mutex_lock], [], AC_MSG_ERROR([libpthread is required])) 114fi 115 116if test "x$enable_debug" = "xyes"; then 117 AC_DEFINE([NL_DEBUG], [1], [Define to 1 to enable debugging]) 118fi 119 120AC_CONFIG_SUBDIRS([doc]) 121 122AC_CONFIG_FILES([ 123Makefile 124libnl.sym 125libnl-3.0.pc 126libnl-route-3.0.pc 127libnl-genl-3.0.pc 128libnl-nf-3.0.pc 129libnl-cli-3.0.pc 130lib/Makefile 131include/Makefile 132src/Makefile 133src/lib/Makefile 134tests/Makefile 135man/Makefile 136python/Makefile 137python/setup.py 138python/doc/Makefile 139python/examples/Makefile 140python/netlink/Makefile 141python/netlink/genl/Makefile 142python/netlink/route/Makefile 143python/tests/Makefile 144include/netlink/version.h 145]) 146 147ac_errcount=0 148if test -z "$YACC"; then 149 AC_MSG_WARN(bison not found.
