Make编译安装php时提示collect2: ld returned 1 exit status make: *** [sapi/cli/php] Error 1是什么问题

在安裝 PHP 到系统中时要是发生「undefined reference to libiconv_open’」之类的错误信息，那表示在「./configure 」沒抓好一些环境变数值。错误发生点在建立「-o sapi/cli/php」是出错，没給到要 link 的 iconv 函式库参数。 解决方法：编辑Makefile 大约77 行左右的地方: EXTRA_LIBS = ….. -lcrypt 在最后加上 -liconv，例如: EXTRA_LIBS = ….. -lcrypt -liconv 然后重新再次 make 即可。
或者用另一种办法
建立软链接
ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/
再执行Make
make ZEND_EXTRA_LIBS=’-liconv’
