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 [2.1.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 AC_CONFIG_MACRO_DIR([m4]) 35 36 37 dnl 38 dnl Increment LIBREVISION if source code has changed at all 39 dnl 40 dnl If the API has changed, increment LIBCURRENT and set LIBREVISION to 0 41 dnl 42 dnl If the API changes compatibly (i.e. simply adding a new function 43 dnl without changing or removing earlier interfaces), then increment LIBAGE. 44 dnl 45 dnl If the API changes incompatibly set LIBAGE back to 0 46 dnl 47 48 LIBCURRENT=7 49 LIBREVISION=0 50 LIBAGE=6 51 52 AC_CONFIG_HEADER(expat_config.h) 53 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_CXX 66 AC_PROG_INSTALL 67 68 if test "$GCC" = yes ; then 69 dnl 70 dnl Be careful about adding the -fexceptions option; some versions of 71 dnl GCC don't support it and it causes extra warnings that are only 72 dnl distracting; avoid. 73 dnl 74 OLDCFLAGS="$CFLAGS -Wall -Wmissing-prototypes -Wstrict-prototypes" 75 CFLAGS="$OLDCFLAGS -fexceptions" 76 AC_MSG_CHECKING(whether $CC accepts -fexceptions) 77 AC_TRY_LINK( , , 78 AC_MSG_RESULT(yes), 79 AC_MSG_RESULT(no); CFLAGS="$OLDCFLAGS") 80 CXXFLAGS=`echo "$CFLAGS" | sed 's/ -Wmissing-prototypes -Wstrict-prototypes//'` 81 fi 82 83 dnl Checks for header files. 84 AC_HEADER_STDC 85 86 dnl Checks for typedefs, structures, and compiler characteristics. 87 88 dnl Note: Avoid using AC_C_BIGENDIAN because it does not 89 dnl work in a cross compile. 90 AC_C_BIGENDIAN_CROSS 91 92 AC_C_CONST 93 AC_TYPE_SIZE_T 94 AC_CHECK_FUNCS(memmove bcopy) 95 96 dnl Only needed for xmlwf: 97 AC_CHECK_HEADERS(fcntl.h unistd.h) 98 AC_TYPE_OFF_T 99 AC_FUNC_MMAP 100 101 if test "$ac_cv_func_mmap_fixed_mapped" = "yes"; then 102 FILEMAP=unixfilemap 103 else 104 FILEMAP=readfilemap 105 fi 106 AC_SUBST(FILEMAP) 107 108 dnl Needed for the test support code; this was found at 109 dnl http://lists.gnu.org/archive/html/bug-autoconf/2002-07/msg00028.html 110 111 # AC_CPP_FUNC 112 # ------------------ # 113 # Checks to see if ANSI C99 CPP variable __func__ works. 114 # If not, perhaps __FUNCTION__ works instead. 115 # If not, we'll just define __func__ to "". 116 AC_DEFUN([AC_CPP_FUNC], 117 [AC_REQUIRE([AC_PROG_CC_STDC])dnl 118 AC_CACHE_CHECK([for an ANSI C99-conforming __func__], ac_cv_cpp_func, 119 [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], 120 [[char *foo = __func__;]])], 121 [ac_cv_cpp_func=yes], 122 [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], 123 [[char *foo = __FUNCTION__;]])], 124 [ac_cv_cpp_func=__FUNCTION__], 125 [ac_cv_cpp_func=no])])]) 126 if test $ac_cv_cpp_func = __FUNCTION__; then 127 AC_DEFINE(__func__,__FUNCTION__, 128 [Define to __FUNCTION__ or "" if `__func__' does not conform to 129 ANSI C.]) 130 elif test $ac_cv_cpp_func = no; then 131 AC_DEFINE(__func__,"", 132 [Define to __FUNCTION__ or "" if `__func__' does not conform to 133 ANSI C.]) 134 fi 135 ])# AC_CPP_FUNC 136 137 AC_CPP_FUNC 138 139 140 dnl Some basic configuration: 141 AC_DEFINE([XML_NS], 1, 142 [Define to make XML Namespaces functionality available.]) 143 AC_DEFINE([XML_DTD], 1, 144 [Define to make parameter entity parsing functionality available.]) 145 AC_DEFINE([XML_CONTEXT_BYTES], 1024, 146 [Define to specify how much context to retain around the current parse point.]) 147 148 AC_CONFIG_FILES([Makefile expat.pc]) 149 AC_OUTPUT 150 151 abs_srcdir="`cd $srcdir && pwd`" 152 abs_builddir="`pwd`" 153 if test "$abs_srcdir" != "$abs_builddir"; then 154 make mkdir-init 155 fi 156
