迷离的夜空，灰黑色的天际悬着一轮金色的孤舟，载着满仓的梦想，驶向云层深处；凉风微微的吹袭着黑夜的素纱，掸掉岁月的风尘；融融的月光静静的流淌，冲断记忆的决堤；零星点点，柔柔的洒在树叶上，泛出浅浅的绿；如华的银色裹住一丝清凉，铺设一地的奢华。

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。
以上就是linux下为php添加iconv模块的方法。坎坷之身须怀壮志之情，穷困之境应无颓唐之意。更多关于linux下为php添加iconv模块的方法请关注haodaima.com其它相关文章！
