# 编译安装php时出现 /encodings.c:101: undefined reference to `libiconv_close’ 错误的解决方法

# 在装php时出现以下的错误：

# /root/Downloads/php-5.6.5/ext/xmlrpc/libxmlrpc/encodings.c:73: undefined reference to `libiconv_open'

# /root/Downloads/php-5.6.5/ext/xmlrpc/libxmlrpc/encodings.c:81: undefined reference to `libiconv'

# /root/Downloads/php-5.6.5/ext/xmlrpc/libxmlrpc/encodings.c:101: undefined reference to `libiconv_close'

# /root/Downloads/php-5.6.5/ext/xmlrpc/libxmlrpc/encodings.c:101: undefined reference to `libiconv_close'

# collect2: error: ld returned 1 exit status

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

# 根据php官网描述这是一个bug（https://bugs.php.net/bug.php?id=52611）。在configure以后要手动修改下Makefile文件，找到EXTRA_LIBS 在最后添加 -liconv 即可顺利通过

# （大约在Makefile文件的104）

# EXTRA_LIBS = -lcrypt -lz -lresolv -lcrypt -lrt -lmysqlclient -lmcrypt -lltdl -lpng -lz -ljpeg -lcurl -lz -lrt -lm -ldl -lnsl -lxml2 -lz -lm -ldl -lssl -lcrypto -lcurl -lxml2 -lz -lm -ldl -lfreetype -lmysqlclient -lz -lm -lssl -lcrypto -ldl -lxml2 -lz -lm
