Compiling PHP 5.3.3 on mac os snow leopard. Issue with iconv linking

I'm trying to recompile PHP 5.3.3 on mac os snow leopard with iconv and getting the following error:

Undefined symbols:
  "_libiconv_open", referenced from:
      _php_iconv_string in iconv.o

I know it's old problem and I could not find the right solution in google.

Any ideas how to fix it will be appreciated.

I'm using:

./configure --prefix=/usr/local/php5 --with-iconv=/usr/local --with-apxs2=/usr/sbin/apxs --enable-pdo --with-gd=/usr/local --with-zlib --with-jpeg-dir=/usr/local/lib --with-png-dir=/usr/local/lib --with-libxml-dir=/usr/local --with-curl --with-mcrypt --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql=/usr/local/mysql --with-mhash --with-libxml-dir=/usr/local --with-t1lib=/usr/local --with-xsl --with-freetype-dir=/usr/local --with-gettext --with-bz2=/usr --with-openssl=/usr/local/ssl --enable-bcmath --enable-calendar --enable-cgi --enable-exif --enable-ftp --enable-gd-native-ttf --enable-mbstring --enable-soap --enable-sqlite-utf8 --enable-cli --enable-wddx --enable-zip

And I have recompiled libiconv 1.13.1 as well.

Hola! I had this same problem on both php 5.3.3 and php 5.3.5. My errors read like this on 5.3.5

Undefined symbols:
  "_libiconv", referenced from:
      __php_iconv_strlen in iconv.o
      _php_iconv_string in iconv.o
      _php_iconv_string in iconv.o
      __php_iconv_strpos in iconv.o
      __php_iconv_appendl in iconv.o
      __php_iconv_appendl in iconv.o
      _zif_iconv_substr in iconv.o
      _zif_iconv_mime_encode in iconv.o
      _zif_iconv_mime_encode in iconv.o
      _zif_iconv_mime_encode in iconv.o
      _zif_iconv_mime_encode in iconv.o
      _zif_iconv_mime_encode in iconv.o
      _zif_iconv_mime_encode in iconv.o
      _php_iconv_stream_filter_append_bucket in iconv.o
      _php_iconv_stream_filter_append_bucket in iconv.o
     (maybe you meant: __libiconv_version)
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [libs/libphp5.bundle] Error 1

the solution is alterations to the file ext/iconv/iconv.c

open it up and change around line 185 to look like this

• #if defined(HAVE_LIBICONV) && defined(ICONV_ALIASED_LIBICONV)
• #define iconv iconv
• #endif

basically changing "libiconv" to just "iconv"

that solution worked for me on both php 5.3.3 and 5.3.5 on snowleopard 10.6.4

peace

This is one of a class of problems compiling PHP on Mac OS X that relates to multiple versions of libraries -- the PHP developers' response is almost invariably "Just delete the extra libraries. Problem solved" -- completely ignoring the fact that there are often quite legitimate reasons to have multiple libs installed. They refuse to address the issue.

covers the case of libxml, but it's a similar problem.
