解決編譯PHP找不到libc-client.a的問題

最近PHP爆出漏洞，老高也在升級PHP版本，並加入一些支援，但是遇到這個問題很蛋疼

configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation.
網上搜了各種教程，各種cp都沒用，索性我們就自己編譯吧！

I. 安裝devel庫

yum install pam-devel libc-client libc-client-devel -y

如果使用了yum安裝了libc-client，那麼在以後編譯參數--with-imap=/usr/local/php-imap中的路徑應該刪除，即--with-imap。

如果這樣還不能解決，那麼就需要手動編譯imap2007f了！

II. 手動編譯imap2007f

指令碼取自 http://forum.directadmin.com/showthread.php?t=45434

在/usr/src目錄下運行以下指令碼，將會在/usr/local/php-imap目錄下產生imap需要的庫

#!/bin/sh

#Is it a 64-bit OS?
B64=0

B64COUNT=`uname -m | grep -c 64`
if [ "$B64COUNT" -eq 1 ]; then
    B64=1
    LD_LIBRARY_PATH=/lib64:/usr/lib64:/usr/local/lib64:/lib:/usr/lib:/usr/local/lib
    export LD_LIBRARY_PATH

if [ ! -e /usr/include/krb5.h ] && [ -e /etc/redhat-release ]; then
    echo "Installing krb5-devel"
    yum -y install krb5-devel

    if [ ${B64} -eq 0 ]; then

exit 0;

III. 開始編譯

下面是編譯PHP的參數，如果出現問題，請參考編譯PHP5.6 和 PHP編譯錯誤的解決辦法。

./configure --prefix=/usr/local/php --with-pdo-pgsql --with-zlib-dir --with-freetype-dir --enable-mbstring --with-libxml-dir=/usr --enable-soap --enable-calendar --with-curl --with-mcrypt --with-zlib --with-gd --with-pgsql --disable-rpath --enable-inline-optimization --with-bz2 --with-zlib --enable-sockets --enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex --enable-exif --enable-bcmath --with-mhash --enable-zip --with-pcre-regex --with-mysql --with-pdo-mysql --with-mysqli --with-jpeg-dir=/usr --with-png-dir=/usr --enable-gd-native-ttf --with-openssl --enable-ftp --with-imap=/usr/local/php-imap --with-imap-ssl --with-kerberos --with-gettext --with-xmlrpc --with-xsl --enable-opcache --enable-fpm --with-fpm-user=www --with-fpm-group=www --disable-fileinfo
IV. 其他問題

在本次編譯中，老高又遇到了幾個怪事

set --enable-opcache=no

configure: error: Don't know how to define struct flock on this system, set --enable-opcache=no
這個問題還是庫檔案的連結問題

解決：

echo /usr/local/lib > /etc/ld.so.conf.d/local.conf
ldconfig -v
讓編譯的PHP支援memcache
