PHP 8.1.28 Released!


この拡張モジュールを使うには、 c-client ライブラリがインストールされている必要があります。 » から 最新版を入手し、コンパイルしてください。

IMAP のソースファイルをシステムの include ディレクトリに直接コピー しないことが大切です。そのようなことをすると既存のファイルと衝突を 引き起こす可能性があります。そのかわりにシステムの include ディレクトリの 下に新しいディレクトリ(例: /usr/local/imap-2000b/ 場所や名前は、あなたのシステムの設定や IMAP のバージョンに依存します)を作成し、 この新規ディレクトリの下に lib/include/ という新しいディレクトリを作成します。IMAP ソースツリーの c-client ディレクトリからすべての *.h ファイルを include/ に、そしてすべての *.c ファイルを lib/ にコピーします。 IMAP をコンパイルすると、c-client.a というファイルが つくられます。これも lib/ ディレクトリにコピーし、 名前を libc-client.a に変更してください。


c-client ライブラリを SSL や Kerberos のサポートつきでビルド するには、パッケージとともに提供されるドキュメントを参照ください。

注意: Mandrake Linux では、IMAP ライブラリ(libc-client.a) が Kerberos のサポートなしでコンパイルされています。また、SSL 対応バージョン(client-PHP4.a)が別に インストールされます。Kerberos サポートを使用するには、これらの ライブラリを再コンパイルする必要があります。

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.

php-imap package is not available neither in Red Hat Enterprise Linux 7 nor 8.

To compile the extension yourself:

# yum install pam-devel openssl-devel

Follow steps 2 and 3 from the previous post of "ldi at email dot cz"

Download the c-client library from github, you can see the link at the top of the page and compile with:
# make lr5 SSLINCLUDE=/usr/include/openssl/ EXTRACFLAGS=-fPIC
(if you are using another distro, instead of lr5 you will type something else, you can view the Makefile for other unix flavors)

Follow step 5 from the previous post of "ldi at email dot cz" which is what the second paragraph at the top of the page explains.

Download the PHP source code of the version installed in your system and go to the php/ext/imap folder.

# phpize
(If you installed the PHP packages from the Red Hat Software Collections you must run the following command before to set the enviroment eg: scl enable rh-php73 bash)

# ./configure --with-imap=<<path_to_where_you_unpacked_the_c-client_library_and_compiled_it>> --with-imap-ssl

# make

This creates the file php/ext/imap/modules/ :)
Copy it to your extension_dir (you can find it in the phpinfo() page).
Create an .ini file in the php.d folder with the text:

Restart apache and be happy.

P.S. You could probably find the extension compiled out there but who knows the trustiness of the source so better to get the official unaltered sources.

It should be noted that the source code archives at the University of Washington, and the mirrors, have been dead for some time.

When compiling IMAP on a 64 bit machine, use: make EXTRACFLAGS=-fPIC.

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

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

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

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.

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 `'

You need to recompile the IMAP library and add -fpic or -fPIC to your CFLAGS.


Also, if you compiled OpenSSL from source, you'll need to do the same, as you'll get error messages for libc-client.a
