我正在尝试使用此配置在我的新计算机上构建PHP：
export MACOSX_DEPLOYMENT_TARGET=10.7 CFLAGS="-arch x86_64" CXXFLAGS="-arch x86_64" LIBS=-lresolv
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib
./configure --prefix=/usr/local --with-apxs2=/usr/sbin/apxs --with-ldap=/usr --with-kerberos=/usr --enable-cli --with-zlib-dir=/usr --enable-exif --enable-ftp --enable-mbstring --enable-mbregex --enable-sockets --with-iodbc=/usr --with-curl=/usr --with-config-file-path=/etc --sysconfdir=/private/etc --with-mysql-sock=/var/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql=/usr/local/mysql --with-openssl=/usr --with-xmlrpc --with-xsl=/usr --without-pear --with-libxml-dir=/usr --with-iconv=/usr/local --with-pdo-mysql=/usr/local/mysql/bin/mysql_config --with-gd --with-jpeg-dir=/usr/local/Cellar --with-png-dir=/usr/X11 --with-freetype-dir=/usr/X11 --with-mcrypt=/usr/local/Cellar --enable-pcntl
配置运行正常，但是当我尝试运行“make”时，它最终会出现此错误：
Generating phar.phar
dyld: Library not loaded: libmysqlclient.18.dylib
Referenced from: /Users/mdiamond/Downloads/php-5.3.8/sapi/cli/php
Reason: image not found

考虑到我指定了“export DYLD_LIBRARY_PATH = / usr / local / mysql / lib”并且libmysqlclient.18.dylib在该路径中，这非常奇怪。似乎链接器正在寻找没有路径的libmysqlclient.18.dylib（在根目录中？）。我还在我的php二进制文件上运行了otool并得到了这个：

请注意libmysqlclient是唯一没有路径的库。有谁知道我怎么解决这个问题？我运行配置错了吗？

我遇到了类似的问题，我认为这与/usr/local/mysql符号链接到我的计算机上的/usr/local/mysql-5.5.15-osx10.6-x86_64（通过DMG安装的MySQL）有关。更改DYLD_LIBRARY_PATH以使用完全限定的路径似乎让make对我有效。
但是，我在make install过程中确实遇到了后续问题。在Installing PEAR environment步骤中出现了相同的错误消息。 问题的解决方案是事先做到这一点：
install_name_tool -change libmysqlclient.18.dylib \
/usr/local/mysql-5.5.15-osx10.6-x86_64/lib/libmysqlclient.18.dylib \
/path/to/php-5.3.8/sapi/cli/php

当我尝试在MacOS X 10.6.8 Snow Leopard上与MariaDB 5.5一起编译PHP 5.4.16时，发生了类似的事情。在make期间，此过程意外停止并显示此错误报告：

我正在使用一大堆非标准目录来运行我的服务器（带有PHP-CGI的apache），因此我的配置设置有点奇怪而且对其他人没有帮助。他们使用MariaDB 5.2为PHP的整个5.4分支工作，直到今天才停止按预期工作。
感谢您的帖子，这就是我想到的，让它再次成功编译和安装（当然，根据自己的要求更改路径）：
在compile之前，设置数据库lib目录的路径：
export DYLD_LIBRARY_PATH=/customserver/maria55/lib
根据需要使用选项运行./compile
make 运行此命令来修复CGI和CLI二进制文件中mysql客户端库的损坏路径：
install_name_tool -change install_name_tool -change libmysqlclient.18.dylib /customserver/maria55/lib/libmysqlclient.18.dylib /sources/php-5.4.16/sapi/cli/php
install_name_tool -change libmysqlclient.18.dylib /customserver/maria55/lib/libmysqlclient.18.dylib /sources/php-5.4.16/sapi/cgi/php-cgi
运行sudo make install
希望这对同样情况下的其他人有帮助
