解决方法
代码如下:
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gztar -zxvf libiconv-1.13.1.tar.gzcd libiconv-1.13.1./configure –prefix=/usr/local/libiconvmakemake install
再检查php
代码如下:
#./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-ic/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。
以上就介绍了linux下为php添加iconv模块的方法，包括了方面的内容，希望对php教程有兴趣的朋友有所帮助。
