This allows us to create an m4 18 dnl symbol holding the correct version number. AC_INIT() requires the 19 dnl version number at m4-time, rather than when ./configure is run, so 20 dnl all this must happen as part of m4, not as part of the shell code 21 dnl contained in ./configure. 22 dnl 23 dnl NOTE: esyscmd() is a GNU M4 extension. Thus, we wrap it in an appropriate 24 dnl test. I believe this test will work, but I don't have a place with non- 25 dnl GNU M4 to test it right now. 26 define([expat_version], ifdef([__gnu__], 27 [esyscmd(conftools/get-version.sh lib/expat.h)], 28 [2.0.x])) 29 AC_INIT(expat, expat_version, expat-bugs (a] libexpat.org) 30 undefine([expat_version]) 31 32 AC_CONFIG_SRCDIR(Makefile.in) 33 AC_CONFIG_AUX_DIR(conftools) 34 35 36 dnl 37 dnl Increment LIBREVISION if source code has changed at all 38 dnl 39 dnl If the API has changed, increment LIBCURRENT and set LIBREVISION to 0 40 dnl 41 dnl If the API changes compatibly (i.e. simply adding a new function 42 dnl without changing or removing earlier interfaces), then increment LIBAGE. 43 dnl 44 dnl If the API changes incompatibly set LIBAGE back to 0 45 dnl 46 47 LIBCURRENT=6 48 LIBREVISION=2 49 LIBAGE=5 50 51 AC_CONFIG_HEADER(expat_config.h) 52 53 sinclude(conftools/libtool.m4) 54 sinclude(conftools/ac_c_bigendian_cross.m4) 55 56 AC_LIBTOOL_WIN32_DLL 57 AC_PROG_LIBTOOL 58 59 AC_SUBST(LIBCURRENT) 60 AC_SUBST(LIBREVISION) 61 AC_SUBST(LIBAGE) 62 63 dnl Checks for programs. 64 AC_PROG_CC 65 AC_PROG_INSTALL 66 67 if test "$GCC" = yes ; then 68 dnl 69 dnl Be careful about adding the -fexceptions option; some versions of 70 dnl GCC don't support it and it causes extra warnings that are only 71 dnl distracting; avoid. 72 dnl 73 OLDCFLAGS="$CFLAGS -Wall -Wmissing-prototypes -Wstrict-prototypes" 74 CFLAGS="$OLDCFLAGS -fexceptions" 75 AC_MSG_CHECKING(whether $CC accepts -fexceptions) 76 AC_TRY_LINK( , , 77 AC_MSG_RESULT(yes), 78 AC_MSG_RESULT(no); CFLAGS="$OLDCFLAGS") 79 CXXFLAGS=`echo "$CFLAGS" | sed 's/ -Wmissing-prototypes -Wstrict-prototypes//'` 80 fi 81 82 dnl Checks for header files. 83 AC_HEADER_STDC 84 85 dnl Checks for typedefs, structures, and compiler characteristics. 86 87 dnl Note: Avoid using AC_C_BIGENDIAN because it does not 88 dnl work in a cross compile. 89 AC_C_BIGENDIAN_CROSS 90 91 AC_C_CONST 92 AC_TYPE_SIZE_T 93 AC_CHECK_FUNCS(memmove bcopy) 94 95 dnl Only needed for xmlwf: 96 AC_CHECK_HEADERS(fcntl.h unistd.h) 97 AC_TYPE_OFF_T 98 AC_FUNC_MMAP 99 100 if test "$ac_cv_func_mmap_fixed_mapped" = "yes"; then 101 FILEMAP=unixfilemap 102 else 103 FILEMAP=readfilemap 104 fi 105 AC_SUBST(FILEMAP) 106 107 dnl Needed for the test support code; this was found at 108 dnl http://lists.gnu.org/archive/html/bug-autoconf/2002-07/msg00028.html 109 110 # AC_CPP_FUNC 111 # ------------------ # 112 # Checks to see if ANSI C99 CPP variable __func__ works. 113 # If not, perhaps __FUNCTION__ works instead. 114 # If not, we'll just define __func__ to "". 115 AC_DEFUN([AC_CPP_FUNC], 116 [AC_REQUIRE([AC_PROG_CC_STDC])dnl 117 AC_CACHE_CHECK([for an ANSI C99-conforming __func__], ac_cv_cpp_func, 118 [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], 119 [[char *foo = __func__;]])], 120 [ac_cv_cpp_func=yes], 121 [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], 122 [[char *foo = __FUNCTION__;]])], 123 [ac_cv_cpp_func=__FUNCTION__], 124 [ac_cv_cpp_func=no])])]) 125 if test $ac_cv_cpp_func = __FUNCTION__; then 126 AC_DEFINE(__func__,__FUNCTION__, 127 [Define to __FUNCTION__ or "" if `__func__' does not conform to 128 ANSI C.]) 129 elif test $ac_cv_cpp_func = no; then 130 AC_DEFINE(__func__,"", 131 [Define to __FUNCTION__ or "" if `__func__' does not conform to 132 ANSI C.]) 133 fi 134 ])# AC_CPP_FUNC 135 136 AC_CPP_FUNC 137 138 139 dnl Some basic configuration: 140 AC_DEFINE([XML_NS], 1, 141 [Define to make XML Namespaces functionality available.]) 142 AC_DEFINE([XML_DTD], 1, 143 [Define to make parameter entity parsing functionality available.]) 144 AC_DEFINE([XML_CONTEXT_BYTES], 1024, 145 [Define to specify how much context to retain around the current parse point.]) 146 147 AC_CONFIG_FILES(Makefile) 148 AC_OUTPUT 149 150 abs_srcdir="`cd $srcdir && pwd`" 151 abs_builddir="`pwd`" 152 if test "$abs_srcdir" != "$abs_builddir"; then 153 make mkdir-init 154 fi 155
