From 5acfd58da0032c752ca9c21d355058e774d5d8d9 Mon Sep 17 00:00:00 2001 From: Michael Wetherell Date: Tue, 22 Aug 2006 21:15:21 +0000 Subject: [PATCH] Add WX_CHECK_DECLS macro and try it out on strtok_r. Otherwise the test for strtok_r succeeds on Minix though the function is not available. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@40754 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- acinclude.m4 | 38 +++++++++++++++++ configure | 118 +++++++++++++++++++++------------------------------ configure.in | 7 ++- 3 files changed, 92 insertions(+), 71 deletions(-) diff --git a/acinclude.m4 b/acinclude.m4 index dcd3a5ecf7..d6c0566e8f 100644 --- a/acinclude.m4 +++ b/acinclude.m4 @@ -227,6 +227,44 @@ AC_DEFUN([WX_CPP_EXPLICIT], fi ]) +dnl --------------------------------------------------------------------------- +dnl WX_CHECK_DECLS(TARGET..., +dnl HEADER, +dnl [ACTION-IF-FOUND], +dnl [ACTION-IF-NOT-FOUND]) +dnl +dnl Checks that the functions, macros or variables listed in TARGET are +dnl declared when HEADER is included. +dnl --------------------------------------------------------------------------- + +AC_DEFUN([WX_CHECK_DECLS], +[ + for target in $1 + do + AC_CACHE_CHECK([for $target in $2], + [wx_cv_decl_$target], + [ + AC_TRY_COMPILE([#include <$2>], + [ + #ifndef $target + &$target; + #endif + ], + [eval wx_cv_decl_$target=yes], + [eval wx_cv_decl_$target=no]) + ]) + + if eval test \$wx_cv_decl_$target = yes + then + AC_DEFINE_UNQUOTED([HAVE_`echo $target | tr 'a-z' 'A-Z'`]) + $3 + else + : + $4 + fi + done +]) + dnl --------------------------------------------------------------------------- dnl a slightly better AC_C_BIGENDIAN macro which allows cross-compiling dnl --------------------------------------------------------------------------- diff --git a/configure b/configure index 3e3da0f653..60e9df6a4e 100755 --- a/configure +++ b/configure @@ -2124,6 +2124,9 @@ _ACEOF echo "$as_me: WARNING: *** System type ${host} is unknown, assuming generic Unix and continuing nevertheless." >&2;} { echo "$as_me:$LINENO: WARNING: *** Please report the build results to wx-dev@lists.wxwidgets.org." >&5 echo "$as_me: WARNING: *** Please report the build results to wx-dev@lists.wxwidgets.org." >&2;} + + DEFAULT_DEFAULT_wxUSE_X11=1 + DEFAULT_wxUSE_SHARED=no esac @@ -2145,7 +2148,7 @@ if test $DEBUG_CONFIGURE = 1; then DEFAULT_wxUSE_THREADS=yes - DEFAULT_wxUSE_SHARED=yes + DEFAULT_wxUSE_SHARED=${DEFAULT_wxUSE_SHARED:-yes} DEFAULT_wxUSE_OPTIMISE=no DEFAULT_wxUSE_PROFILE=no DEFAULT_wxUSE_NO_DEPS=no @@ -2359,7 +2362,7 @@ else DEFAULT_wxUSE_THREADS=yes - DEFAULT_wxUSE_SHARED=yes + DEFAULT_wxUSE_SHARED=${DEFAULT_wxUSE_SHARED:-yes} DEFAULT_wxUSE_OPTIMISE=yes DEFAULT_wxUSE_PROFILE=no DEFAULT_wxUSE_NO_DEPS=no @@ -28758,7 +28761,7 @@ _ACEOF cat confdefs.h >>conftest.$ac_ext cat >>conftest.$ac_ext <<_ACEOF /* end confdefs.h. */ -#include +#include _ACEOF if { (eval echo "$as_me:$LINENO: \"$ac_cpp conftest.$ac_ext\"") >&5 (eval $ac_cpp conftest.$ac_ext) 2>conftest.er1 @@ -28785,7 +28788,7 @@ else sed 's/^/| /' conftest.$ac_ext >&5 for ac_dir in $ac_x_header_dirs; do - if test -r "$ac_dir/X11/Xlib.h"; then + if test -r "$ac_dir/X11/Intrinsic.h"; then ac_x_includes=$ac_dir break fi @@ -28799,18 +28802,18 @@ if test "$ac_x_libraries" = no; then # See if we find them without any special options. # Don't add to $LIBS permanently. ac_save_LIBS=$LIBS - LIBS="-lX11 $LIBS" + LIBS="-lXt $LIBS" cat >conftest.$ac_ext <<_ACEOF /* confdefs.h. */ _ACEOF cat confdefs.h >>conftest.$ac_ext cat >>conftest.$ac_ext <<_ACEOF /* end confdefs.h. */ -#include +#include int main () { -XrmInitialize () +XtMalloc (0) ; return 0; } @@ -28848,7 +28851,7 @@ for ac_dir in `echo "$ac_x_includes $ac_x_header_dirs" | sed s/include/lib/g` do # Don't even attempt the hair of trying to link an X program!
