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