Bug #11654: configure fails on iconv_open

From: tom@minnesota.com Operating system: NetBSD/Alpha 1.5W-current PHP version: 4.0.6 PHP Bug Type: Sablotron XSL Bug description: configure fails on iconv_open Sablot-0.60 (also 0.5x), PHP-4.0.7-dev i tried 'configure' with and without --iconv-dir=/usr/pkg flag. in either case, i get the following error: ---cut--- configure:46596: checking for iconv_open in -lc configure:46615: gcc -o conftest -DLIBICONV_PLUG -DNETBSD -DEAPI -DUSE_EXPAT -I/usr/pkg/include -Wl,-export-dynamic -Wl,-R/usr/lib -L/usr/lib -Wl,-R/usr/pkg/lib -L/usr/pkg/lib -Wl,-R/usr/ local/lib -L/usr/local/lib -Wl,-R/usr/X11R6/lib -L/usr/X11R6/lib -L/usr/pkg/lib -R/usr/pkg/lib -L/usr/pkg/lib -R/usr/local/lib/mysql -L/usr/local/lib/mysql -R/usr/local/lib -L/usr/local/lib co nftest.c -lc -lexpat -lexpat -lsablot -lpq -lmysqlclient -lz -lgd -lttf -lz -lcrypt -lresolv -lm -lz -lpng -lm -lc -lpng -ljpeg -lttf -lintl -lXpm -lX11 -lresolv -lgcc 1>&5 /tmp/ccpa03fT.o: In function `main': conftest.c(.text+0x18): undefined reference to `iconv_open' conftest.c(.text+0x1c): undefined reference to `iconv_open' collect2: ld returned 1 exit status configure: failed program was: #line 46604 "configure" #include "confdefs.h" /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char iconv_open(); int main() { iconv_open() ; return 0; } ---cut--- the type declared above doesn't match with libiconv's type for iconv_open (should be iconv_t instead of char). in addition, iconv_open is an alias function for libiconv_open and therefore will fail if "#include <iconv.h>" isn't included. here is my env setup: ---cut--- rm config.cache export LIBS="-lz -lpng -lm -lc -lpng -ljpeg -lttf -lintl -lXpm -lX11" && \ export LDFLAGS="-Wl,-export-dynamic \ -Wl,-R/usr/lib -L/usr/lib \ -Wl,-R/usr/pkg/lib -L/usr/pkg/lib \ -Wl,-R/usr/local/lib -L/usr/local/lib \ -Wl,-R/usr/X11R6/lib -L/usr/X11R6/lib" ./configure \ --with-apxs \ --disable-pear \ --with-gd=/usr/pkg \ --with-sablot=/usr/local \ --with-expat-dir=/usr/local \ --without-iconv \ <== tried w/ --with-iconv=/usr/local also --with-pgsql=/usr/local \ --with-mysql=/usr/local \ --enable-libgcc \ --with-gnu-ld \ --with-zlib \ --with-system-regex \ --with-config-file-path=/usr/local/etc \ --enable-track-vars \ --enable-force-cgi-redirect \ --enable-discard-path \ --enable-memory-limit \ --enable-sysvsem \ --enable-sysvshm \ --enable-sockets \ --with-ttf=/usr/pkg \ --enable-freetype-4bit-antialias-hack ---cut--- please note, according to the docs from Sablot, iconv support is optional. i think php's config needs to change to reflect the use of libiconv with Sablot 0.5X - 0.60. -- Edit Bug report at: http://bugs.php.net/?id=11654&edit=1
