PHP + IMAP on 64Bit machines

[FransVanNispen]

Given the time I have spend solving this problem and all posts I have seen from people with similar problems, still unsolved, I figured a small post on this here might be appreciated.

The two typical errors:

1. configure: error: Cannot find imap library (libc-client.a). Please check your IMAP installation.

2. Check the path given to --with-kerberos (if no path is given, searches in /usr/kerberos, /usr/local and /usr )

The problem seems to be caused by mixture of 32bit and 64bit static code, with which the linker has trouble relocating.

So, how can you fix this? Use PIC-code:

1. Make sure kereberos is installed: yum install krb5 krb5-devel

2. Install the libc-client. This must be the one from DA, as it contains small modifications for virtual accounts (as I read on this forum).

cd /usr/local/directadmin/customapache
wget http://files.directadmin.com/services/da_imap-2004g.tar.gz
tar -zxvf da_imap-2004g.tar.gz
cd imap-2004g

Modify the Makefile for the libc-client to use PIC-code:

Find these lines:

#EXTRACFLAGS= DA CHANGED
EXTRACFLAGS=-I/usr/kerberos/include -L/usr/kerberos/lib

And change them to (only added option -fPIC):

#EXTRACFLAGS= DA CHANGED
EXTRACFLAGS=-I/usr/kerberos/include -L/usr/kerberos/lib -fPIC

./buildit
cd c-client
mkdir /usr/local/imap-2004g/
mkdir /usr/local/imap-2004g/lib
mkdir /usr/local/imap-2004g/include
cp *.h /usr/local/imap-2004g/include
cp *.c /usr/local/imap-2004g/lib
cp c-client.a /usr/local/imap-2004g/lib
mv /usr/local/imap-2004g/lib/c-client.a /usr/local/imap-2004g/lib/libc-client.a

3. Modify the configure.php (or configure.php_ap2 for Apache2) file:

cd /usr/local/directadmin/customapache
vi configure.php

Remove option: --with-kerberos

Add options:
--enable-pic \
--with-libdir=lib64 \
--with-imap=/usr/local/imap-2000e


4. Compile PHP:

./build clean
./build php_ap2 n (for Apache2, for Apache1 use: ./build php n)


Now you should end up with a working PHP+IMAP. Just need to restart Apache to load the new version:

/sbin/service httpd restart (or restart from DA)

Frans, with this info i succeeded with PHP 4.4.7, but now upgrading to php 5.2.4 following the instructions on DA i get:

configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation.

My configure.php:

#!/bin/sh
./configure \
--with-apxs \
--with-curl \
--with-curl-dir=/usr/local/lib \
--with-gd \
--with-gd-dir=/usr/local/lib \
--with-freetype \
--with-freetype-dir=/usr/local/lib \
--with-gettext \
--with-jpeg-dir=/usr/local/lib \
--with-mcrypt \
--with-mhash \
--with-mysql=/usr \
--with-pear \
--with-png-dir=/usr/local/lib \
--with-xml \
--with-zlib \
--with-zlib-dir=/usr/local/lib \
--with-zip \
--with-openssl \
--enable-bcmath \
--enable-calendar \
--enable-ftp \
--enable-magic-quotes \
--enable-sockets \
--enable-track-vars \
--enable-mbstring \
--enable-memory-limit \
--enable-pic \
--with-libdir=lib64 \
--with-imap=/usr/local/imap-2004g

Any suggestion for me ?

Hi Cees,

It means that you either didn't do step 2, or something went wrong in that step as it is the basic fault to start with.

 

[cpisuisse]

Hi Frans,

I followed step 2 and reinstalled this to make sure, does not change the problem however.

Hi again Frans,

When i remove the line with:

--with-libdir=lib64 \

from configure.php it gets installed.
Would leaving this cause problems ?

An alternative to this on CentOS 64, is to simply:

# yum install libc-client-devel.x86_64
# ln -s /usr/lib64/libc-client.a /usr/lib/libc-client.a

Adding --with-imap should now no longer throw libc-client.a errors.

I tried the options here but still receive errors.

-lm -lcrypt -lxml2 -lz -liconv -lm -lxml2 -lz -liconv -lm -lxml2 -lz -liconv -lm -lcrypt  -o sapi/cli/php

Any ideas?

THE BETTER WAY FOR install it on centos5.x 64 bits :

# yum install libc-client-devel.x86_64
# ln -s /usr/lib64/libc-client.a /usr/lib/libc-client.a

make clean your install php and compile php with these options in your configure options of php

--with-imap=/usr/lib64/
--with-imap-ssl

if you have an error
# yum install pam-devel
and retry
