make: *** [sapi/cli/php] Error 1

解决方法:

#wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
#tar -zxvf libiconv-1.13.1.tar.gz
#cd libiconv-1.13.1
# ./configure --prefix=/usr/local/libiconv
# make
# make install

方法一:法为去除iconv模块也能正常编译php,如下:
編輯 Makefile 大約 77 行左右的地方:
EXTRA_LIBS = ..... -lcrypt
在最後加上 -liconv,例如:
EXTRA_LIBS = ..... -lcrypt -liconv

再检查php,指定 iconv的位置  --with-iconv=/usr/local/libiconv
#./configure --prefix=/usr/local/php52 --with-iconv=/usr/local/libiconv
#make
#make install

再运行make就可以了。

最后一种方法:

#make ZEND_EXTRA_LIBS='-liconv'
#make install
