How to compile PHP with OpenSSL on OS X 10.9?

问题

I'm trying to compile PHP 5.6.10 from the source, and I encountered the following problem:

Undefined symbols for architecture x86_64:
  "_PKCS5_PBKDF2_HMAC", referenced from:
      _zif_openssl_pbkdf2 in openssl.o
  "_TLSv1_1_client_method", referenced from:
      _php_openssl_setup_crypto in xp_ssl.o
  "_TLSv1_1_server_method", referenced from:
      _php_openssl_setup_crypto in xp_ssl.o
  "_TLSv1_2_client_method", referenced from:
      _php_openssl_setup_crypto in xp_ssl.o
  "_TLSv1_2_server_method", referenced from:
      _php_openssl_setup_crypto in xp_ssl.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libs/libphp5.bundle] Error 1

OpenSSL is installed via Brew. In PHP included like --with-openssl=/usr/local/Cellar/openssl/1.0.2c

P.S. Before tried to use just /usr for OpenSSL but got the same error.

回答1:

The Makefile has a line with EXTRA_LIBS, something like:

EXTRA_LIBS = -lresolv -lmcrypt -lltdl -liconv-lm -lxml2 -lcurl -lssl -lcrypto

Remove all occurrences of -lssl and -lcrypto and add the full path to libssl.dylib and libcrypto.dylib (brew links openssl to /usr/local/opt/openssl/lib/)

EXTRA_LIBS = -lresolv -lmcrypt /usr/local/opt/openssl/lib/libssl.dylib /usr/local/opt/openssl/lib/libcrypto.dylib -lltdl -liconv-lm -lxml2 -lcurl

To follow up on Bob Fanger's answer (which worked perfectly for me on os x 10.11.3), here's a little script you can run from within the build directory that makes the Makefile changes:

#!/usr/bin/php
<?php
if (true != copy('Makefile', 'Makefile.sav'))
    die("** cannot copy 'Makefile' to 'Makefile.sav'\n");
$lines = file('Makefile');
if (false == $lines)
    die("** connot read 'Makefile'\n");
$output = fopen('Makefile', 'wb');
if (false == $output)
    die("** unable to open 'Makefile'\n");
foreach ($lines as $line) {
    if (preg_match('/^EXTRA_LIBS\s+=\s+/', $line)) {
        $line = preg_replace('/^EXTRA_LIBS\s+=\s+/', 'EXTRA_LIBS = /usr/local/opt/openssl/lib/libssl.dylib /usr/local/opt/openssl/lib/libcrypto.dylib', $line);
        $line = preg_replace(['/-lssl/', '/-lcrypto/'], [], $line);
    }
    if (false === fwrite($output, $line))
        die("** writing line to 'Makefile' failed\n");
}
fclose($output);
echo "Success - your Makefile is set for ssl\n";

Enjoy!
