安装re2c

brew install re2c

安装libiconv

brew install libiconv

./configure --enable-debug --with-iconv=/opt/homebrew/opt/libiconv -prefix=/Users/xiaoyu/Desktop/software_source_reader/read-php-src-master/php-src/source/

make -j4

报错一修复，修改文件main/reentrancy.c改成下面这行

报错二修复

将Zend/zend_language_parser.c中添加如下两行

报错三修复

将makefile文件中的EXTRA_LIBS中的-liconv -liconv 修改为 -liconv /opt/homebrew/opt/libiconv/lib/libiconv.dylib

报错四修复

./configure --enable-debug --with-iconv=/opt/homebrew/opt/libiconv --without-pear --disable-phar -prefix=/Users/xiaoyu/Desktop/software_source_reader/read-php-src-master/php-src/source/
make clean
make -j4 && make install
