Update of /cvsroot/dirac/compress/m4 In directory sc8-pr-cvs12.sourceforge.net:/tmp/cvs-serv28533/m4 Added Files: acinclude.m4 ax_create_stdint_h.m4 Log Message: Use autoconf macro AX_CREATE_STDINT_H to create a local stdint file because different versions of gcc have the "ISO C9X: 7.18 Integer types" in different header files. MS VC++ does not define these types so manually typedef the ones used in Dirac (int64_t and uint64_t) to MSVC++ types. --- NEW FILE: acinclude.m4 --- dnl dnl $Id: acinclude.m4,v 1.1 2008/05/06 09:35:51 asuraparaju Exp $ $Name: $ dnl AC_DEFUN([AC_TRY_CXXFLAGS], [AC_MSG_CHECKING([if $CXX supports $3 flags]) SAVE_CXXFLAGS="$CXXFLAGS" CXXFLAGS="$3" AC_COMPILE_IFELSE([AC_LANG_PROGRAM([[$1]], [[$2]])],[ac_cv_try_cxxflags_ok=yes], [ac_cv_try_cxxflags_ok=no]) CXXFLAGS="$SAVE_CXXFLAGS" AC_MSG_RESULT([$ac_cv_try_cxxflags_ok]) if test x"$ac_cv_try_cxxflags_ok" = x"yes"; then ifelse([$4],[],[:],[$4]) else ifelse([$5],[],[:],[$5]) fi]) --- NEW FILE: ax_create_stdint_h.m4 --- # ============================================================ =============== # http://autoconf-archive.cryp.to/ax_create_stdint_h.html # ============================================================ =============== # # SYNOPSIS # # AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])] # # DESCRIPTION # # the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the # existence of an include file <stdint.h> that defines a set of typedefs, # especially uint8_t,int32_t,uintptr_t. Many older installations will not # provide this file, but some will have the very same definitions in # <inttypes.h>. In other enviroments we can use the inet-types in # <sys/types.h> which would define the typedefs int8_t and u_int8_t # respectivly. # # This macros will create a local "_stdint.h" or the headerfile given as # an argument. In many cases that file will just "#include <stdint.h>" or # "#include <inttypes.h>", while in other environments it will provide the # set of basic 'stdint's definitions/typedefs: # # int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,ui ntptr_t # int_least32_t.. int_fast32_t.. intmax_t # # which may or may not rely on the definitions of other files, or using # the AC_CHECK_SIZEOF macro to determine the actual sizeof each type. # # if your header files require the stdint-types you will want to create an # installable file mylib-int.h that all your other installable header may # include. So if you have a library package named "mylib", just use # # AX_CREATE_STDINT_H(mylib-int.h) # # in configure.ac and go to install that very header file in Makefile.am # along with the other headers (mylib.h) - and the mylib-specific headers # can simply use "#include <mylib-int.h>" to obtain the stdint-types. # # Remember, if the system already had a valid <stdint.h>, the generated # file will include it directly. No need for fuzzy HAVE_STDINT_H things... # (oops, GCC 4.2.x has deliberatly disabled its stdint.h for non-c99 # compilation and the c99-mode is not the default. Therefore this macro # will not use the compiler's stdint.h - please complain to the GCC # developers). # # LAST MODIFICATION # # 2008-04-12 # # COPYLEFT # # Copyright (c) 2008 Guido U.
