问题描述

在 Mac 电脑中,编译 PHP 5系列(5.4.45/5.5.38/5.6.40)的源码。运行以下命令。

$ ./configure  --prefix=/opt/php-5.4.45 --enable-fpm --with-mysql
$ make

在运行 make 的时候,报错了。

Undefined symbols for architecture x86_64:

解决方法

Mac 自带了 libiconv,但是并适合 PHP 5。

1. 重新安装 libiconv

运行 brew 重新安装 libiconv

brew install libiconv

查看 libiconv.dylib的路径,我的电脑是在 /usr/local/Cellar/libiconv/1.16/lib/libiconv.dylib

2. 修改 Makefile

打开当前目录的 Makefile 文件,搜索 -liconv,找到以下一行。

EXTRA_LIBS = -lresolv -liconv -liconv -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm

删除 -liconv,并在行最后,添加第一步的 libiconv.dylib 路径。修改结果如下。

- EXTRA_LIBS = -lresolv -liconv -liconv -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm

+ EXTRA_LIBS = -lresolv -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm /usr/local/Cellar/libiconv/1.16/lib/libiconv.dylib

3. 重新编译

$ make
$ sudo make install
