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".
