我希望用imap支持安装php（--with-imap），但是我收到了这个错误。
checking for U8T_DECOMPOSE...
configure: error: utf8_mime2text() has new signature, but U8T_CANONICAL is
missing. This should not happen. Check config.log for additional information.
版本php是5.6.24（在Centos7 64上），命令运行它是
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql --enable-sockets --with-snmp --enable-mbstring --with-curl --with-gd --with-mysqli --with-imap
yum install libc-client.x86_64
Package libc-client-2007f-4.el7.1.x86_64 already installed and latest version
Nothing to do
