Description:
------------
The gd module can include undefined references to the following symbols..

         U libiconv
         U libiconv_close
         U libiconv_open

If compiled as a shared module, it can only load if something else w/ a libiconv dependency has loaded before it.  On systems where GD detects libconv during configuration, -liconv should be added to GD_SHARED_LIBADD so the runtime linker can resolve those symbols.

It looks like libiconv is only mentioned in gdkanji.c, but I had the same problem regardless of whether I built php with --enable-gd-jis-conv or not.

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

Can't reproduce.
Also there is no '--with-iconv-lib' option neither in 5.x, nor in 4.3 branch.

With php5-200506272030 exact the same problem as my posting of Jun 12 is recurring. BTW, when I do grep on ./configure --help, I get -
[php5-200506272030]$ ./configure --help | grep iconv
  --without-iconv[=DIR]   Exclude iconv support
  --with-iconv-dir=DIR      XMLRPC-EPI: iconv dir for XMLRPC-EP
tony2001, are you saying that you are not seeing this, or this option actually is null? This option is not helping resolve the problem anyways, though.

Same problem with Solaris 10 and the latest snapshot (php5-200508190830).

./configure --with-apxs=/usr/local/apache/bin/apxs --with-zlib --with-jpeg-dir --with-png-dir --with-config-file-path=/usr/local/apache/conf --with-gd --with-freetype-dir=/usr/sfw --enable-gd-native-ttf --with-pgsql --with-dom --enable-mbstring --with-xmlrpc

Make dies with:

Undefined                       first referenced
 symbol                             in file
libiconv_close                      ext/gd/libgd/.libs/gdkanji.o
libiconv_open                       ext/gd/libgd/.libs/gdkanji.o
libiconv                            ext/gd/libgd/.libs/gdkanji.o
ld: fatal: Symbol referencing errors. No output written to sapi/cli/php
collect2: ld returned 1 exit status
make: *** [sapi/cli/php] Error 1

And as suggested, adding -liconv to EXTRA_LIBS in Makefile by hand fixes the problem.

Also by using --disable-mbstring it will work fine..
 [2005-08-19 14:04 UTC] pajoye@php.net 
We cannot fix that now.

With the unicode, mbstring will be useless here.

Sorry, do it manually until php and unicode are available in a release.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.
