Next: PHP+Apache suddenly not working
From: Mari Masuda on 24 Oct 2009 18:33
Hi,

I am setting up my Mac Book Pro running Mac OS X 10.6.1 as a
development environment for Drupal. I already successfully have MySQL
5.1.40 and Apache 2.2.11 up and running. I tried to compile PHP
5.2.11 in the following manner and keep getting an error. Any help
would be great!

1. Downloaded php-5.2.11.tar.gz from php.net. The MD5 checksum of
the downloaded file is the same as what is listed on php.net so I do
not think the file is corrupt.
2. Expanded php-5.2.11.tar.gz by double-clicking the file I
downloaded and moving the resulting folder (named "php-5.2.11") to my
desktop.

In terminal did the following (I am following the instructions in the
box labeled "Example #1 Installation Instructions (Apache 2 Shared
Module Version)" at http://www.php.net/manual/en/install.unix.apache2.php
)
3. cd /Users/mari/Desktop/php-5.2.11
4. ./configure --prefix=/Applications/php --disable-short-tags --with-
mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config
--with-apxs2=/Applications/apache/bin/apxs --enable-mbstring --with-
pdo-mysql=/usr/local/mysql
5. make

At this point, make does not complete and it exits with an error:

---start error---
Undefined symbols:
"_res_9_dn_expand", referenced from:
_zif_dns_get_mx in dns.o
"_res_9_search", referenced from:

_zif_dns_get_mx in dns.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [libs/libphp5.bundle] Error 1
---end error---

To try to simplify things, I deleted the php-5.2.11 folder I created
in step 2 above and repeated steps 2 and 3. Then at this point I only
did ./configure by itself with no options, thinking that I could try
to see if any of my configuration options were causing the issue.
Alas, no, the problem still happens; the error is now this:

---start error---
Undefined symbols:
"_res_9_dn_expand", referenced from:
_zif_dns_get_mx in dns.o

ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [sapi/cgi/php-cgi] Error 1
---end error---

What can I do to get around this problem and compile PHP? Thanks!

Hi,

So I found out there are two bugs filed in bugs.php.net that are
related to this problem. The bugs are http://bugs.php.net/bug.php?id=49332and
http://bugs.php.net/bug.php?id=49267.

To anyone else that has the same issues as me, here is how to get
around the problem if you are trying to compile a freshly downloaded
copy of PHP 5.2.11 on Mac OS X 10.6.1.

1. First, open <php-5.2.11>/ext/iconv/iconv.c and edit line 197.
Lines 196-198 look like this originally:
---
#ifdef HAVE_LIBICONV
#define iconv libiconv
#endif
---
You need to change it to look like this:
---
#ifdef HAVE_LIBICONV
#define iconv iconv
#endif
---

2. When you run ./configure, prepend LIBS=-lresolv so the resulting
command is:
---
LIBS=-lresolv ./configure <...your options here...>
---

Now when you run make you should not get a compilation error and you
should be able to follow the rest of the instructions on http://www.php.net/manual/en/install.unix.apache2.php
to get your PHP 5.2.11 up and running.
