AGE is always dnl *changed* at the same time. dnl - AGE (Micro): Increment if any interfaces have been added; set to 0 dnl if any interfaces have been removed. 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 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 C:A:R dnl 12:0:1 0.6.13 dnl 13:1:0 added EXIF_DATA_OPTION_DONT_CHANGE_MAKER_NOTE (for 0.6.14) dnl 14:2:0 added XP_ WinXP tags (for 0.6.15) dnl 14:2:1 0.6.17 dnl 15:3:0 added exif_loader_get_buf (for 0.6.18) dnl 15:3:1 0.6.19 dnl 15:3:2 0.6.20 dnl 15:3:3 0.6.21 dnl 15:3:4 0.6.22 LIBEXIF_CURRENT=15 LIBEXIF_AGE=3 LIBEXIF_REVISION=4 AC_SUBST([LIBEXIF_AGE]) AC_SUBST([LIBEXIF_REVISION]) AC_SUBST([LIBEXIF_CURRENT]) AC_SUBST([LIBEXIF_CURRENT_MIN],[`expr $LIBEXIF_CURRENT - $LIBEXIF_AGE`]) LIBEXIF_VERSION_INFO="$LIBEXIF_CURRENT:$LIBEXIF_REVISION:$LIBEXIF_AGE" AC_SUBST([LIBEXIF_VERSION_INFO]) AC_C_INLINE AM_PROG_AR LT_INIT([win32-dll]) AM_CPPFLAGS="$CPPFLAGS" GP_CONFIG_MSG([Compiler], [${CC}]) dnl -------------------------------------------------------------------- dnl check for "diff" and "diff -u" dnl -------------------------------------------------------------------- AC_ARG_VAR([DIFF], [path to diff utility (default: no)]) AC_PATH_PROG([DIFF], [diff], [no]) AM_CONDITIONAL([HAVE_DIFF], [test "x$DIFF" != xno]) DIFF_U="no" AS_IF([test "x$DIFF" != xno], [dnl AC_MSG_CHECKING([whether diff supports -u]) echo moo > conftest-a.c echo moo > conftest-b.c AS_IF([${DIFF} -u conftest-a.c conftest-b.c], [dnl AC_MSG_RESULT([yes]) DIFF_U="$DIFF -u" ], [dnl AC_MSG_RESULT([no]) ]) rm -f conftest-a.c conftest-b.c ]) AC_SUBST([DIFF_U]) AM_CONDITIONAL([HAVE_DIFF_U], [test "x$DIFF_U" != xno]) dnl -------------------------------------------------------------------- AC_SYS_LARGEFILE dnl Create a stdint.h-like file containing size-specific integer definitions dnl that will always be available AX_NEED_STDINT_H([libexif/_stdint.h]) dnl ------------------------------------------------------------------------ dnl Whether we're supposed to ship binaries in the tarball dnl ------------------------------------------------------------------------ ship_binaries=false AC_ARG_ENABLE([ship-binaries], [AS_HELP_STRING([--enable-ship-binaries], [Whether to ship binaries in the tarball [default=no]])], [ AS_VAR_IF([enableval], [yes], [ship_binaries=true]) ]) AM_CONDITIONAL([SHIP_BINARIES], [$ship_binaries]) GP_CONFIG_MSG([Ship binaries in tarball], [$ship_binaries]) dnl --------------------------------------------------------------------------- dnl Whether -lm is required for our math functions dnl --------------------------------------------------------------------------- # we need sqrt and pow which may be in libm # We cannot use AC_CHECK_FUNC because if CFLAGS contains # -Wall -Werror here the check fails because # char *sqrt() conflicts with double sqrt(double xx) # Start by assuming -lm is needed, because it's possible that the little # test program below will be optimized to in-line floating point code that # doesn't require -lm, whereas the library itself cannot be so optimized # (this actually seems to be the case on x86 with gcc 4.2).
