From 6d2139e829308254b581fef7db96984dacd975b1 Mon Sep 17 00:00:00 2001 From: Vadim Zeitlin Date: Tue, 22 Feb 2011 13:26:00 +0000 Subject: [PATCH] Test for cairo_push_group() in configure. This function is required by wxGraphicsContext Cairo-based implementation but is missing in old Cairo versions so check for it in configure and disable wxGraphicsContext is it's not available. Closes #12966. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@66995 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- configure | 111 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++--- configure.in | 24 +++++++++---- 2 files changed, 125 insertions(+), 10 deletions(-) diff --git a/configure b/configure index fea56a8..07d613a 100755 --- a/configure +++ b/configure @@ -48320,14 +48320,117 @@ echo "${ECHO_T}yes" >&6; } wx_has_graphics=1 fi if test "$wx_has_graphics" = 1; then - cat >>confdefs.h <<\_ACEOF + save_LIBS="$LIBS" + LIBS="$LIBS $CAIRO_LIBS" + +for ac_func in cairo_push_group +do +as_ac_var=`echo "ac_cv_func_$ac_func" | $as_tr_sh` +{ echo "$as_me:$LINENO: checking for $ac_func" >&5 +echo $ECHO_N "checking for $ac_func... $ECHO_C" >&6; } +if { as_var=$as_ac_var; eval "test \"\${$as_var+set}\" = set"; }; then + echo $ECHO_N "(cached) $ECHO_C" >&6 +else + cat >conftest.$ac_ext <<_ACEOF +/* confdefs.h. */ +_ACEOF +cat confdefs.h >>conftest.$ac_ext +cat >>conftest.$ac_ext <<_ACEOF +/* end confdefs.h. */ +/* Define $ac_func to an innocuous variant, in case declares $ac_func. + For example, HP-UX 11i declares gettimeofday. */ +#define $ac_func innocuous_$ac_func + +/* System header to define __stub macros and hopefully few prototypes, + which can conflict with char $ac_func (); below. + Prefer to if __STDC__ is defined, since + exists even on freestanding compilers. */ + +#ifdef __STDC__ +# include +#else +# include +#endif + +#undef $ac_func + +/* Override any GCC internal prototype to avoid an error. + Use char because int might match the return type of a GCC + builtin and then its argument prototype would still apply. */ +#ifdef __cplusplus +extern "C" +#endif +char $ac_func (); +/* The GNU C library defines this for functions which it implements + to always fail with ENOSYS.
