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 [2.2.x])) 29AC_INIT(expat, expat_version, expat-bugs@libexpat.org) 30undefine([expat_version]) 31 32AC_CONFIG_SRCDIR(Makefile.in) 33AC_CONFIG_AUX_DIR(conftools) 34AC_CONFIG_MACRO_DIR([m4]) 35 36 37dnl 38dnl Increment LIBREVISION if source code has changed at all 39dnl 40dnl If the API has changed, increment LIBCURRENT and set LIBREVISION to 0 41dnl 42dnl If the API changes compatibly (i.e. simply adding a new function 43dnl without changing or removing earlier interfaces), then increment LIBAGE. 44dnl 45dnl If the API changes incompatibly set LIBAGE back to 0 46dnl 47 48LIBCURRENT=7 # sync 49LIBREVISION=2 # with 50LIBAGE=6 # CMakeLists.txt! 51 52AC_CONFIG_HEADER(expat_config.h) 53 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_CXX 66AC_PROG_INSTALL 67 68if 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 if test "x$CXXFLAGS" = x ; then 81 CXXFLAGS=`echo "$CFLAGS" | sed 's/ -Wmissing-prototypes -Wstrict-prototypes//'` 82 fi 83fi 84 85dnl Checks for header files. 86AC_HEADER_STDC 87 88dnl Checks for typedefs, structures, and compiler characteristics. 89 90dnl Note: Avoid using AC_C_BIGENDIAN because it does not 91dnl work in a cross compile. 92AC_C_BIGENDIAN_CROSS 93 94AC_C_CONST 95AC_TYPE_SIZE_T 96AC_CHECK_FUNCS(memmove bcopy) 97 98dnl Only needed for xmlwf: 99AC_CHECK_HEADERS(fcntl.h unistd.h) 100AC_TYPE_OFF_T 101AC_FUNC_MMAP 102 103if test "$ac_cv_func_mmap_fixed_mapped" = "yes"; then 104 FILEMAP=unixfilemap 105else 106 FILEMAP=readfilemap 107fi 108AC_SUBST(FILEMAP) 109 110dnl Needed for the test support code; this was found at 111dnl http://lists.gnu.org/archive/html/bug-autoconf/2002-07/msg00028.html 112 113# AC_CPP_FUNC 114# ------------------ # 115# Checks to see if ANSI C99 CPP variable __func__ works. 116# If not, perhaps __FUNCTION__ works instead. 117# If not, we'll just define __func__ to "". 118AC_DEFUN([AC_CPP_FUNC], 119[AC_REQUIRE([AC_PROG_CC_STDC])dnl 120AC_CACHE_CHECK([for an ANSI C99-conforming __func__], ac_cv_cpp_func, 121[AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], 122[[char *foo = __func__;]])], 123 [ac_cv_cpp_func=yes], 124 [AC_COMPILE_IFELSE([AC_LANG_PROGRAM([], 125[[char *foo = __FUNCTION__;]])], 126 [ac_cv_cpp_func=__FUNCTION__], 127 [ac_cv_cpp_func=no])])]) 128if test $ac_cv_cpp_func = __FUNCTION__; then 129 AC_DEFINE(__func__,__FUNCTION__, 130 [Define to __FUNCTION__ or "" if `__func__' does not conform to 131ANSI C.]) 132elif test $ac_cv_cpp_func = no; then 133 AC_DEFINE(__func__,"", 134 [Define to __FUNCTION__ or "" if `__func__' does not conform to 135ANSI C.]) 136fi 137])# AC_CPP_FUNC 138 139AC_CPP_FUNC 140 141 142dnl Some basic configuration: 143AC_DEFINE([XML_NS], 1, 144 [Define to make XML Namespaces functionality available.]) 145AC_DEFINE([XML_DTD], 1, 146 [Define to make parameter entity parsing functionality available.]) 147AC_DEFINE([XML_CONTEXT_BYTES], 1024, 148 [Define to specify how much context to retain around the current parse point.]) 149 150AC_CONFIG_FILES([Makefile expat.pc]) 151AC_OUTPUT 152 153abs_srcdir="`cd $srcdir && pwd`" 154abs_builddir="`pwd`" 155if test "$abs_srcdir" != "$abs_builddir"; then 156 make mkdir-init 157fi 158
