Add WITHOUT_IPV6 knob (Requested by Jens Rehsack in PR 53754, implemented in a slightly different way). Add GIF and animated GIF write support by default in GD and add WITH_LZW knob to enable the LZW compression algorithm (patented in some countries). Removed gd_gif_out.diff patch and added many new patches. >How-To-Repeat: >Fix: --- php4.diff begins here --- diff -ruN php4.orig/Makefile php4/Makefile --- php4.orig/Makefile Wed Jun 25 03:35:17 2003 +++ php4/Makefile Sat Jun 28 17:15:10 2003 @@ -63,7 +63,7 @@ USE_SUBMAKE= yes GNU_CONFIGURE= yes USE_BISON= yes -USE_LIBTOOL= yes +USE_LIBTOOL_VER=14 CONFIGURE_ARGS= --enable-versioning \ --enable-memory-limit \ @@ -126,7 +126,7 @@ .include -.if ${OSVERSION} < 400014 +.if ${OSVERSION} < 400014 || defined(WITHOUT_IPV6) CONFIGURE_ARGS+=--disable-ipv6 .endif @@ -303,6 +303,9 @@ LIB_DEPENDS+= Xpm.4:${PORTSDIR}/x11/XFree86-4-libraries CONFIGURE_ARGS+=--with-xpm-dir=${LOCALBASE} .endif +.if defined(WITH_LZW) +CONFIGURE_ARGS+=--enable-gd-lzw-gif +.endif .endif .if defined(WITH_GDBM) @@ -570,13 +573,11 @@ @${SETENV} ${SCRIPTS_ENV} ${SH} ${SCRIPTDIR}/configure.php post-patch: -.if defined(WITH_GD_GIF_OUT) - @${PATCH} -b .orig -d ${WRKSRC} -N -s -E -p1 -t < ${FILESDIR}/gd_gif_out.diff -.endif @${SED} "s|%%PREFIX%%|${PREFIX}|g" \ ${WRKSRC}/pear/scripts/pearcmd.php > ${WRKSRC}/pear/scripts/pear pre-configure: + @${ECHO_CMD} "" .if defined(WITH_IMAP) && defined(WITH_RECODE) @${ECHO_CMD} "You cannot define WITH_IMAP *and* WITH_RECODE!" @${FALSE} @@ -593,8 +594,11 @@ @${ECHO_CMD} "You cannot define WITH_SYBASEDB *and* WITH_SYBASECT!" @${FALSE} .endif -.if !defined(WITHOUT_APACHE) && !defined(WITHOUT_CLI) +.if defined(WITH_GD) && !defined(WITH_LZW) + @${ECHO_CMD} "To enable LZW-compressed GIF support in GD define the WITH_LZW knob." @${ECHO_CMD} "" +.endif +.if !defined(WITHOUT_APACHE) && !defined(WITHOUT_CLI) @${ECHO_CMD} "You are building the Apache Module and the Command Line Interpreter of PHP." @${ECHO_CMD} "" @${ECHO_CMD} "Use port:" diff -ruN php4.orig/files/gd_gif_out.diff php4/files/gd_gif_out.diff --- php4.orig/files/gd_gif_out.diff Mon Jun 23 15:06:55 2003 +++ php4/files/gd_gif_out.diff Thu Jan 1 01:00:00 1970 @@ -1,1418 +0,0 @@ -diff -ruN php-4.3.3RC1.orig/configure php-4.3.3RC1/configure ---- php-4.3.3RC1.orig/configure Mon Jun 23 10:06:05 2003 -+++ php-4.3.3RC1/configure Mon Jun 23 10:06:17 2003 -@@ -28248,7 +28248,7 @@ - libgd/gd_io_file.c libgd/gd_ss.c libgd/gd_io_ss.c libgd/gd_png.c libgd/gd_jpeg.c \ - libgd/gdxpm.c libgd/gdfontt.c libgd/gdfonts.c libgd/gdfontmb.c libgd/gdfontl.c \ - libgd/gdfontg.c libgd/gdtables.c libgd/gdft.c libgd/gdcache.c libgd/gdkanji.c \ -- libgd/wbmp.c libgd/gd_wbmp.c libgd/gdhelpers.c libgd/gd_topal.c libgd/gd_gif_in.c \ -+ libgd/wbmp.c libgd/gd_wbmp.c libgd/gdhelpers.c libgd/gd_topal.c libgd/gd_gif_in.c libgd/gd_gif_out.c \ - libgd/xbm.c" - - for ac_func in fabsf floorf -@@ -29724,6 +29724,9 @@ - - cat >> confdefs.h <<\EOF - #define HAVE_GD_BUNDLED 1 -+#define HAVE_GD_GIF_CREATE 1 -+#define HAVE_GD_GIF_CTX 1 -+#define HAVE_GD_GIF_ANIM 1 - EOF - - cat >> confdefs.h <<\EOF -@@ -32260,6 +32263,60 @@ - LDFLAGS=$save_old_LDFLAGS - cat >> confdefs.h <<\EOF - #define HAVE_GD_GIF_CTX 1 -+EOF -+ -+ -+else -+ echo "$ac_t""no" 1>&6 -+ -+ LDFLAGS=$save_old_LDFLAGS -+ unset ac_cv_func_gd -+ -+ -+fi -+ -+ -+ save_old_LDFLAGS=$LDFLAGS -+ LDFLAGS=" -L$GD_LIB $GD_SHARED_LIBADD $LDFLAGS" -+ echo $ac_n "checking for gdImageGifAnimBegin in -lgd""... $ac_c" 1>&6 -+echo "configure:32003: checking for gdImageGifAnimBegin in -lgd" >&5 -+ac_lib_var=`echo gd'_'gdImageGifAnimBegin | sed 'y%./+-%__p_%'` -+if eval "test \"`echo '$''{'ac_cv_lib_$ac_lib_var'+set}'`\" = set";
