Compiling the IMAP Server

Once you have unpacked the files by extracting the tar archive, "cd" to the "cyrus-imapd-NNNN" directory where NNNN is the version number. The configuration files and various subdirectories are stored there. In the directory that the configure file is in, type "./configure" to configure the software. Please continue to read this document as there are switches to ./configure that may apply to you.

configure Overview

The "configure" shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a "Makefile" in each directory of the package. Finally, it creates a shell script "config.status" that you can run in the future to recreate the current configuration, a file "config.cache" that saves the results of its tests to speed up reconfiguring, and a file "config.log" containing compiler output (useful mainly for debugging "configure").

Running "configure" takes awhile. While running, it prints some messages telling which features it is checking for.

You can compile the package in a different directory from the one containing the source code. Doing so allows you to compile it on more than one kind of computer at the same time. To do this, you must use a version of "make" that supports the "VPATH" variable, such as GNU "make". "cd" to the directory where you want the object files and executables to go and run the "configure" script. "configure" automatically checks for the source code in the directory that "configure" is in and in "..".

By default, "make install" will install files (other than server-specific programs) in "/usr/local/bin", "/usr/local/man", etc. You can specify an installation prefix other than "/usr/local" by giving "configure" the option "--prefix=PATH".

You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give "configure" the option "--exec-prefix=PATH", the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix.

By default, "make install" will install the server-specific programs in "/usr/cyrus/bin". You can specify a server-specific installation prefix other than "/usr/cyrus" by giving "configure" the option "--with-cyrus-prefix=PATH".

Options to configure

Here are a list of switches that can be used with "configure". 3

--help
Print a summary of the options to "configure", and exit.

--with-auth=METHOD
Specifies the authorization (group membership) module to use. Currently implemented authorization modules are:
unix
Unix /etc/passwd and /etc/group file
krb
Kerberos principals (requires Kerberos libraries). Optionally, specify where to find Kerberos v4 with "--with-krb=DIR" IMPORTANT: The Kerberos v4 support requires the DES library. Some vendor distributions of Kerberos, including the one with Solaris, do not have this support and cannot be used.
krb_pts
Kerberos principals with AFS PTserver groups (requires Kerberos and AFS libraries). Optionally, specify where the AFS libraries are found with "--with-afs=PATH". Also requires krb support as above.
Any method of authenticating with SASL can be used with any authorization module.

--with-cyrus-group=USER
Specifies the group used for installing setguid programs. By default, configure uses "mail".

--with-cyrus-prefix=PATH
Change the location of the server software. By default, the cyrus-prefix is /usr/cyrus.

--with-cyrus-user=USER
Specifies the userid that the Cyrus IMAP server will run as. By default, configure uses "cyrus".

--with-notify=METHOD
--without-notify
Specifies the new mail notification method to use. Currently implemented notification methods are:
zephyr
New mail notification through Zephyr. Specify the location of the zephyr installation with "--with-zephyr=PATH".
unix
New mail notification through a Unix sockets daemon. See overview.html for details.
no
No new mail notification.
By default, uses "zephyr" if the Zephyr libraries are available, otherwise "no".

--with-idle=METHOD
Specifies the IMAP IDLE method to use. Currently implemented IDLE methods are:
idled
Use the IDLE daemon. The IDLE daemon listens on a UNIX socket for messages from lmtpd/imapd/pop3d that a mailbox has been updated. The daemon then signals those (if any) imapd that are idling on the mailbox to check for the changes.
poll
Periodically poll the mailbox for changes.
no
Disable IMAP IDLE.
By default, uses "poll".

--with-sasldir=PATH
Specifies the path to the directories containing the library (.../lib) and include (.../include) files for libsasl.

--with-statedir=PATH
Specifies the directory used for communicating with various daemons. By default, configure uses "/var".

--with-openssl=PATH
Specifies where to find the OpenSSL library.

--with-inn=PATH
Specifies the location of INN's NEWSLIB directory. By default, looks for INN in a few common places. It is only necessary for "configure" to find INN if you are going to export newsgroups using IMAP.

--with-tcl=PATH
--without-tcl
Specifies the path to the Tcl (version 7.5 or 7.6) library and header file (optional). By default, looks in "/usr/local" and then in the compiler's default link path. The Tcl library is necessary to compile "cyradm", the administrative client. If compiling without Tcl, it is necessary to give configure the "--disable-cyradm" switch.

--with-lock=METHOD
Specifies the locking method to use. Currently implemented locking methods are:
flock
flock() locking
fcntl
fcntl() locking
By default, uses "flock" if the "flock()" function exists, "fcntl" otherwise.

--disable-sieve
By default, Sieve support is enabled. Use --disable-sieve to disable compiling the Sieve library and to disable all Sieve support.

--disable-cyradm
Do not compile the cyradm administrative client.

--disable-server
Do not compile the IMAP server programs.

"configure" ignores any other arguments that you give it.

Some systems require unusual options for compilation or linking that the "configure" script does not know about. You can give "configure" initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: 

   CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the "env" program, you can do it like this: 
   env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
The "make" variables that you might want to override with environment variables when running "configure" are:
CC
C compiler program.
Default is "cc", or "gcc" if "gcc" is in your PATH.
(For "CC", any value given in the environment overrides the value that "configure" would choose.)
CFLAGS
Debugging and optimization options for the C compiler.
CPPFLAGS
Header file search directory ("-IDIR") and any other miscellaneous options for the C preprocessor and compiler. If it is not set in the environment when "configure" runs, the default value is empty.
LDFLAGS
Stripping ("-s") and any other miscellaneous options for the linker. If it is not set in the environment when "configure" runs, the default value is empty.
DEFS
Configuration options, in the form "-Dfoo -Dbar ..."
LIBS
Libraries to link with, in the form "-lfoo -lbar ..."
(For "DEFS" and "LIBS", any value given in the environment is added to the value that "configure" chooses.)
If you need to do unusual things to compile the package, we encourage you to figure out how "configure" could check whether to do them. After doing so, please send us a patch! Instructions for doing so can be found on the feedback page.

The file "configure.in" is used as a template to create "configure" by a program called "autoconf". You will only need it if you want to regenerate "configure" using a newer version of "autoconf".

Once you have successfully run "configure", execute the following commands: 

   make depend
   make all CFLAGS=-O
If you want, you can override the "make" variables CFLAGS and LDFLAGS by entering the following: 
   make all CFLAGS=-O2 LDFLAGS=-s
