Removal has dnl precedence over adding, so set to 0 if both happened. dnl It denotes upward compatibility. dnl - REVISION (Minor): Increment any time the source changes; set to dnl 0 if you incremented CURRENT. dnl - CURRENT (Major): Increment if the interface has changes. AGE is always dnl *changed* at the same time. dnl dnl To summarize. Any interface *change* increment CURRENT. If that interface dnl change does not break upward compatibility (ie it is an addition), dnl increment AGE, Otherwise AGE is reset to 0. If CURRENT has changed, dnl REVISION is set to 0, otherwise REVISION is incremented. dnl --------------------------------------------------------------------------- dnl A:R:C=6:1:6 libgphoto2_port-0.6.1 libgphoto2-2.2.1 dnl A:R:C=7:0:7 libgphoto2_port-0.7.0 libgphoto2-2.3 dnl A:R:C=7:1:7 libgphoto2_port-0.7.1 libgphoto2-2.3.x dnl A:R:C=8:0:8 libgphoto2_port-0.8.0 libgphoto2-2.4.x dnl A:R:C=9:1:9 libgphoto2_port-0.10.0 libgphoto2-2.5.x dnl A:R:C=1:0:13 libgphoto2-2.5.30 (added gp_port_init_localedir ... ) dnl A:R:C=2:0:14 libgphoto2-2.5.31 (added gpi_libltdl_mutex ... ) AC_SUBST([LIBGPHOTO2_PORT_AGE], [2]) AC_SUBST([LIBGPHOTO2_PORT_REVISION], [0]) AC_SUBST([LIBGPHOTO2_PORT_CURRENT], [14]) AC_SUBST([LIBGPHOTO2_PORT_CURRENT_MIN], [`expr $LIBGPHOTO2_PORT_CURRENT - $LIBGPHOTO2_PORT_AGE`]) AC_SUBST([LIBGPHOTO2_PORT_VERSION_INFO], [$LIBGPHOTO2_PORT_CURRENT:$LIBGPHOTO2_PORT_REVISION:$LIBGPHOTO2_PORT_AGE]) dnl --------------------------------------------------------------------------- dnl Checks for programs. dnl --------------------------------------------------------------------------- AC_PROG_CC AC_PROG_CPP AC_PROG_INSTALL AC_PROG_SED AM_PROG_AR dnl check for/set up libtool and libltdl m4_pattern_forbid([^LT_PREREQ])dnl LT_PREREQ([2.4.2]) dnl Disable building static library, as no one uses it anyway. m4_pattern_forbid([^LT_INIT])dnl LT_INIT([ disable-static dlopen win32-dll ]) dnl dnl LTDL_INIT([external]) dnl dnl We are using our own libltdl checks instead of LTDL_INIT because dnl we do not want to ship our own two copies of libltdl (one for dnl libgphoto2 and one for libgphoto2_port), and LTDL_INIT insists on dnl that.
