1 2dnl AC_SNPRINTFV_CONVENIENCE[(dir)] - sets LIBSNPRINTFV to the link flags for 3dnl the snprintfv convenience library and INCSNPRINTFV to the include flags for 4dnl the snprintfv header and adds --enable-snprintfv-convenience to the 5dnl configure arguments. Note that AC_CONFIG_SUBDIRS is not called. If DIR 6dnl is not provided, it is assumed to be `snprintfv'. LIBSNPRINTFV will be 7dnl prefixed with '${top_builddir}/' and INCSNPRINTFV will be prefixed with 8dnl '${top_srcdir}/' (note the single quotes!). If your package is not 9dnl flat and you're not using automake, define top_builddir and 10dnl top_srcdir appropriately in the Makefiles. 11AC_DEFUN([AC_SNPRINTFV_CONVENIENCE], 12[case $enable_snprintfv_convenience in 13 no) AC_MSG_ERROR([this package needs a convenience snprintfv]) ;; 14 "") enable_snprintfv_convenience=yes 15 ac_configure_args="$ac_configure_args --enable-snprintfv-convenience" ;; 16 esac 17 LIBSNPRINTFV='${top_builddir}/'ifelse($#,1,[$1],['snprintfv'])/snprintfv/libsnprintfvc.la 18 INCSNPRINTFV='-I${top_builddir}/'ifelse($#,1,[$1],['snprintfv'])' -I${top_srcdir}/'ifelse($#,1,[$1],['snprintfv']) 19 AC_SUBST(LIBSNPRINTFV) 20 AC_SUBST(INCSNPRINTFV) 21]) 22 23AC_DEFUN([INVOKE_SNPRINTFV_MACROS],[ 24 AC_SNPRINTFV_CONVENIENCE 25 # ---------------------------------------------------------------------- 26 # Set up and process configure options 27 # ---------------------------------------------------------------------- 28 AC_ARG_ENABLE(snprintfv-install, 29 [ --enable-snprintfv-install install libsnprintfv [yes]]) 30 AM_CONDITIONAL(INSTALL_SNPRINTFV, 31 test x"${enable_snprintfv_install-no}" != xno) 32 AM_CONDITIONAL(CONVENIENCE_SNPRINTFV, 33 test x"${enable_snprintfv_convenience-no}" != xno) 34 AM_CONDITIONAL(SUBDIR_SNPRINTFV, 35 test x"${enable_subdir-no}" != xno) 36 37 AM_WITH_DMALLOC 38 AC_PROG_AWK 39 40 # ---------------------------------------------------------------------- 41 # check for various programs used during the build. 42 # On OS/X, "wchar.h" needs "runetype.h" to work properly. 43 # ---------------------------------------------------------------------- 44 AC_CHECK_HEADERS([runetype.h wchar.h], [], [],[ 45 AC_INCLUDES_DEFAULT 46 #if HAVE_RUNETYPE_H 47 # include <runetype.h> 48 #endif 49 ]) 50 dnl am_cv_prog_cc_stdc is set by AC_PROG_CC_STDC 51 case x$am_cv_prog_cc_stdc in 52 xno) 53 # Non ansi C => won't work with stdarg.h 54 AC_CHECK_HEADER(varargs.h) 55 ;; 56 *) 57 case x$ac_cv_header_varargs_h in 58 xyes) 59 # Parent package is using varargs.h which is incompatible with 60 # stdarg.h, so we do the same. 61 AC_CHECK_HEADER(varargs.h) 62 ;; 63 *) 64 # If stdarg.h is present define HAVE_STDARG_H, otherwise if varargs.h 65 # is present define HAVE_VARARGS_H. 66 AC_CHECK_HEADERS(stdarg.h varargs.h, break) 67 ;; 68 esac 69 ;; 70 esac 71 72 case x$ac_cv_header_stdarg_h$ac_cv_header_varargs_h in 73 x*yes*) ;; 74 *) AC_MSG_ERROR(Could not find either stdarg.h or varargs.h.) ;; 75 esac 76 77 # ---------------------------------------------------------------------- 78 # Checks for typedefs 79 # ---------------------------------------------------------------------- 80 AC_CHECK_TYPES(wchar_t) 81 AC_CHECK_TYPES(wint_t, [], [], [ 82 AC_INCLUDES_DEFAULT 83 #if HAVE_RUNETYPE_H 84 # include <runetype.h> 85 #endif 86 #if HAVE_WCHAR_H 87 # include <wchar.h> 88 #endif 89 ]) 90 AC_CHECK_TYPES([long double]) 91 92 # ---------------------------------------------------------------------- 93 # Checks for library calls 94 # ---------------------------------------------------------------------- 95 AC_REPLACE_FUNCS(strtoul ldexpl frexpl) 96 AC_CHECK_LIB(m, log) 97 AC_CHECK_FUNCS(copysign copysignl) 98]) 99
