AGE is always 41dnl *changed* at the same time. 42dnl - AGE (Micro): Increment if any interfaces have been added; set to 0 43dnl if any interfaces have been removed. Removal has 44dnl precedence over adding, so set to 0 if both happened. 45dnl It denotes upward compatibility. 46dnl - REVISION (Minor): Increment any time the source changes; set to 47dnl 0 if you incremented CURRENT. 48dnl 49dnl To summarize. Any interface *change* increment CURRENT. If that interface 50dnl change does not break upward compatibility (ie it is an addition), 51dnl increment AGE, Otherwise AGE is reset to 0. If CURRENT has changed, 52dnl REVISION is set to 0, otherwise REVISION is incremented. 53dnl --------------------------------------------------------------------------- 54dnl C:A:R 55dnl 12:0:1 0.6.13 56dnl 13:1:0 added EXIF_DATA_OPTION_DONT_CHANGE_MAKER_NOTE (for 0.6.14) 57dnl 14:2:0 added XP_ WinXP tags (for 0.6.15) 58dnl 14:2:1 0.6.17 59dnl 15:3:0 added exif_loader_get_buf (for 0.6.18) 60dnl 15:3:1 0.6.19 61dnl 15:3:2 0.6.20 62dnl 15:3:3 0.6.21 63LIBEXIF_CURRENT=15 64LIBEXIF_AGE=3 65LIBEXIF_REVISION=3 66AC_SUBST([LIBEXIF_AGE]) 67AC_SUBST([LIBEXIF_REVISION]) 68AC_SUBST([LIBEXIF_CURRENT]) 69AC_SUBST([LIBEXIF_CURRENT_MIN],[`expr $LIBEXIF_CURRENT - $LIBEXIF_AGE`]) 70LIBEXIF_VERSION_INFO="$LIBEXIF_CURRENT:$LIBEXIF_REVISION:$LIBEXIF_AGE" 71AC_SUBST([LIBEXIF_VERSION_INFO]) 72 73AC_PROG_CC 74AC_C_CONST 75AC_C_INLINE 76dnl FIXME: AC_LIBTOOL_WIN32_DLL 77AM_PROG_LIBTOOL 78AM_CPPFLAGS="$CPPFLAGS" 79GP_CONFIG_MSG([Compiler],[${CC}]) 80 81 82dnl Create a stdint.h-like file containing size-specific integer definitions 83dnl that will always be available 84AX_NEED_STDINT_H([libexif/_stdint.h]) 85 86 87dnl ------------------------------------------------------------------------ 88dnl Whether we're supposed to ship binaries in the tarball 89dnl ------------------------------------------------------------------------ 90 91ship_binaries=false 92AC_ARG_ENABLE([ship-binaries], 93[AS_HELP_STRING([--enable-ship-binaries], 94[Whether to ship binaries in the tarball [default=no]])],[ 95 if test x$enableval = xyes; then 96 ship_binaries=true 97 fi 98]) 99AM_CONDITIONAL([SHIP_BINARIES],[$ship_binaries]) 100GP_CONFIG_MSG([Ship binaries in tarball],[$ship_binaries]) 101 102 103dnl --------------------------------------------------------------------------- 104dnl Whether -lm is required for our math functions 105dnl --------------------------------------------------------------------------- 106 107# we need sqrt and pow which may be in libm 108# We cannot use AC_CHECK_FUNC because if CFLAGS contains 109# -Wall -Werror here the check fails because 110# char *sqrt() conflicts with double sqrt(double xx) 111 112# Start by assuming -lm is needed, because it's possible that the little 113# test program below will be optimized to in-line floating point code that 114# doesn't require -lm, whereas the library itself cannot be so optimized 115# (this actually seems to be the case on x86 with gcc 4.2).
