collect2: ld returned 1 exit status

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

再检查php

#./configure --with-mysql=/backup/mysql --with-freetype-dir

--with-jpeg-dir --with-png-dir --with-zlib --with-curl --with-gd

--enable-gd-native-ttf --with-apxs2=/usr/local/apache/bin/apxs

--enable-sockets --with-iconv=/usr/local/libiconv

#make

#make install

另一种解决方法为去除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

再运行make就可以了。
