Version 1.4.x had RELEASE of 1.4. 73 # 74 # Ideally, we would not be using RELEASE at all; instead we could just 75 # use the VERSION_INFO field to label our backward-incompatible ABI 76 # changes, and those would be few and far between. Unfortunately, 77 # Libevent still exposes far too many volatile structures in its 78 # headers, so we pretty much have to assume that most development 79 # series will break ABI compatibility. For now, it's simplest just to 80 # keep incrementing the RELEASE between series and resetting VERSION_INFO. 81 # 82 # Eventually, when we get to the point where the structures in the 83 # headers are all non-changing (or not there at all!), we can shift to 84 # a more normal worldview where backward-incompatible ABI changes are 85 # nice and rare. For the next couple of years, though, 'struct event' 86 # is user-visible, and so we can pretty much guarantee that release 87 # series won't be binary-compatible. 88 89 if INSTALL_LIBEVENT 90 dist_bin_SCRIPTS = event_rpcgen.py 91 endif 92 93 pkgconfigdir=$(libdir)/pkgconfig 94 LIBEVENT_PKGCONFIG=libevent.pc 95 96 # These sources are conditionally added by configure.in or conditionally 97 # included from other files. 98 PLATFORM_DEPENDENT_SRC = \ 99 epoll_sub.c \ 100 arc4random.c 101 102 EXTRA_DIST = \ 103 LICENSE \ 104 autogen.sh \ 105 event_rpcgen.py \ 106 libevent.pc.in \ 107 make-event-config.sed \ 108 Doxyfile \ 109 whatsnew-2.0.txt \ 110 Makefile.nmake test/Makefile.nmake \ 111 $(PLATFORM_DEPENDENT_SRC) 112 113 LIBEVENT_LIBS_LA = libevent.la libevent_core.la libevent_extra.la 114 if PTHREADS 115 LIBEVENT_LIBS_LA += libevent_pthreads.la 116 LIBEVENT_PKGCONFIG += libevent_pthreads.pc 117 endif 118 if OPENSSL 119 LIBEVENT_LIBS_LA += libevent_openssl.la 120 LIBEVENT_PKGCONFIG += libevent_openssl.pc 121 endif 122 123 if INSTALL_LIBEVENT 124 lib_LTLIBRARIES = $(LIBEVENT_LIBS_LA) 125 pkgconfig_DATA = $(LIBEVENT_PKGCONFIG) 126 else 127 noinst_LTLIBRARIES = $(LIBEVENT_LIBS_LA) 128 endif 129 130 SUBDIRS = . include sample test 131 132 if BUILD_WIN32 133 134 SYS_LIBS = -lws2_32 -lshell32 -ladvapi32 135 SYS_SRC = win32select.c evthread_win32.c buffer_iocp.c event_iocp.c \ 136 bufferevent_async.c 137 SYS_INCLUDES = -IWIN32-Code 138 139 else 140 141 SYS_LIBS = 142 SYS_SRC = 143 SYS_INCLUDES = 144 145 endif 146 147 if SELECT_BACKEND 148 SYS_SRC += select.c 149 endif 150 if POLL_BACKEND 151 SYS_SRC += poll.c 152 endif 153 if DEVPOLL_BACKEND 154 SYS_SRC += devpoll.c 155 endif 156 if KQUEUE_BACKEND 157 SYS_SRC += kqueue.c 158 endif 159 if EPOLL_BACKEND 160 SYS_SRC += epoll.c 161 endif 162 if EVPORT_BACKEND 163 SYS_SRC += evport.c 164 endif 165 if SIGNAL_SUPPORT 166 SYS_SRC += signal.c 167 endif 168 169 BUILT_SOURCES = include/event2/event-config.h 170 171 include/event2/event-config.h: config.h make-event-config.sed 172 test -d include/event2 || $(MKDIR_P) include/event2 173 $(SED) -f $(srcdir)/make-event-config.sed < config.h > $@T 174 mv -f $@T $@ 175 176 CORE_SRC = event.c evthread.c buffer.c \ 177 bufferevent.c bufferevent_sock.c bufferevent_filter.c \ 178 bufferevent_pair.c listener.c bufferevent_ratelim.c \ 179 evmap.c log.c evutil.c evutil_rand.c strlcpy.c $(SYS_SRC) 180 EXTRA_SRC = event_tagging.c http.c evdns.c evrpc.c 181 182 if BUILD_WITH_NO_UNDEFINED 183 NO_UNDEFINED = -no-undefined 184 MAYBE_CORE = libevent_core.la 185 else 186 NO_UNDEFINED = 187 MAYBE_CORE = 188 endif 189 190 GENERIC_LDFLAGS = -version-info $(VERSION_INFO) $(RELEASE) $(NO_UNDEFINED) 191 192 libevent_la_SOURCES = $(CORE_SRC) $(EXTRA_SRC) 193 libevent_la_LIBADD = @LTLIBOBJS@ $(SYS_LIBS) 194 libevent_la_LDFLAGS = $(GENERIC_LDFLAGS) 195 196 libevent_core_la_SOURCES = $(CORE_SRC) 197 libevent_core_la_LIBADD = @LTLIBOBJS@ $(SYS_LIBS) 198 libevent_core_la_LDFLAGS = $(GENERIC_LDFLAGS) 199 200 if PTHREADS 201 libevent_pthreads_la_SOURCES = evthread_pthread.c 202 libevent_pthreads_la_LIBADD = $(MAYBE_CORE) 203 libevent_pthreads_la_LDFLAGS = $(GENERIC_LDFLAGS) 204 endif 205 206 libevent_extra_la_SOURCES = $(EXTRA_SRC) 207 libevent_extra_la_LIBADD = $(MAYBE_CORE) $(SYS_LIBS) 208 libevent_extra_la_LDFLAGS = $(GENERIC_LDFLAGS) 209 210 if OPENSSL 211 libevent_openssl_la_SOURCES = bufferevent_openssl.c 212 libevent_openssl_la_LIBADD = $(MAYBE_CORE) $(OPENSSL_LIBS) 213 libevent_openssl_la_LDFLAGS = $(GENERIC_LDFLAGS) 214 endif 215 216 noinst_HEADERS = util-internal.h mm-internal.h ipv6-internal.h \ 217 evrpc-internal.h strlcpy-internal.h evbuffer-internal.h \ 218 bufferevent-internal.h http-internal.h event-internal.h \ 219 evthread-internal.h ht-internal.h defer-internal.h \ 220 minheap-internal.h log-internal.h evsignal-internal.h evmap-internal.h \ 221 changelist-internal.h iocp-internal.h \ 222 ratelim-internal.h \ 223 WIN32-Code/event2/event-config.h \ 224 WIN32-Code/tree.h \ 225 compat/sys/queue.h 226 227 EVENT1_HDRS = event.h evhttp.h evdns.h evrpc.h evutil.h 228 229 if INSTALL_LIBEVENT 230 include_HEADERS = $(EVENT1_HDRS) 231 else 232 noinst_HEADERS += $(EVENT1_HDRS) 233 endif 234 235 AM_CPPFLAGS = -I$(srcdir)/compat -I$(srcdir)/include -I./include $(SYS_INCLUDES) 236 237 verify: check 238 239 doxygen: FORCE 240 doxygen $(srcdir)/Doxyfile 241 FORCE: 242 243 DISTCLEANFILES = *~ libevent.pc ./include/event2/event-config.h 244 245
