This extension requires the c-client library to be installed. Grab the latest version from ยป ftp://ftp.cac.washington.edu/imap/ and compile it.
It's important that you do not copy the IMAP source files directly into the system include directory as there may be conflicts. Instead, create a new directory inside the system include directory, such as /usr/local/imap-2000b/ (location and name depend on your setup and IMAP version), and inside this new directory create additional directories named lib/ and include/. From the c-client directory from your IMAP source tree, copy all the *.h files into include/ and all the *.c files into lib/. Additionally when you compiled IMAP, a file named c-client.a was created. Also put this in the lib/ directory but rename it as libc-client.a.
Note:
To build the c-client library with SSL or/and Kerberos support read the docs supplied with the package.
Note: In Mandrake Linux, the IMAP library (libc-client.a) is compiled without Kerberos support. A separate version with SSL (client-PHP4.a) is installed. The library must be recompiled in order to add Kerberos support.
For those using Ubuntu and who are completely daunted by compiling this, it's easy under Ubuntu:
Install libc-client-dev
# sudo apt-get install libc-client-dev
Install PHP5 imap:
# sudo apt-get install php5-imap
Restart Apache
# sudo service apache2 reload
Should work for most people.
Spent hours and hours on compiling PHP with IMAP support on CentOS 64-bit but after many trial and error sessions I got if fixed.
If you have set the '--with-libdir=lib64' flag and you encounter the the 'cannot find the c-client library' error while compiling, try to create a symlink 'lib64' to 'lib' in your imap installation dir.
Apparantly, PHP will search only in lib64 directories if the flag is set. This also applies on the IMAP library but documentation lacks on this point.
After few hours of testing it on CentOS 5 64 bit I'd like to share the steps required to compile imap with php:
1. Install openssl:
yum install openssl openssl-devel
2. If you don't have openssl compiled and installed in /usr/local/ssl create symlink:
ln -s /usr/lib64/openssl/engines/ /usr/local/ssl
3. Add the libraries:
ln -s /usr/include/ /usr/local/ssl/include
4. Compile IMAP
cd /path/to/imap_src
make lnp SSLTYPE=unix
5. Copy files as described above
mkdir lib
mkdir include
cp c-client/*.c lib/
cp c-client/*.h include/
cp c-client/c-client.a lib/libc-client.a
6. Compile PHP
cd /path/to/php/src
./configure --with-imap=/path/to/imap_src --with-libdir=lib64
A more secure & easy way to do this on Debian 7.7, php 5.4:
apt-get install php5-imap
Packages installed
libc-client2007e mlock php5-imap
When compiling IMAP 2007f with php 5.3.27 on a 64 bit OL5.7 machine, add in the Makefile: EXTRACFLAGS=-fPIC and EXTRAAUTHENTICATORS=gss
If you run into an error similar to the following when compiling / making PHP:
errno 0x21c /usr/local/imap-2007e/lib/libc-client.a(netmsg.o)
ld: fatal: relocations remain against allocatable but non-writable sections
make: Fatal error: Command failed for target `libphp5.la'
You need to recompile the IMAP library and add -fpic or -fPIC to your CFLAGS.
See:
http://bugs.php.net/bug.php?id=35465
Also, if you compiled OpenSSL from source, you'll need to do the same, as you'll get error messages for libc-client.a
