Obtaining General Build Information

The --info, or -i retrieves the options (flags) used when building Mailutils. It may be used with or without arguments.

When used without arguments, it prints the list of all build flags, e.g.:

     $ mailutils-config --info
     VERSION=0.4.1
     USE_LIBPAM
     HAVE_LIBLTDL
     WITH_GDBM
     WITH_GNUTLS
     WITH_GSASL
     WITH_GUILE
     WITH_PTHREAD
     WITH_READLINE
     HAVE_MYSQL
     ENABLE_VIRTUAL_DOMAINS
     ENABLE_IMAP
     ENABLE_POP
     ENABLE_MH
     ENABLE_MAILDIR
     ENABLE_SMTP
     ENABLE_SENDMAIL

This option also accepts any number of arguments. When these are given, each argument is treated as a name of a build flag. Mailutils-config checks if such a flag was defined and prints its full name if so. It exits with zero code if all the flags given on the command line are defined. Otherwise, it exits with code of 1.

The comparison of the flag names is case-insensitive. The arguments given need not include the leading prefix (i.e. the characters up to and including the first underscore character).

Given the previous example, the invocation

     $ mailutils --info readline use_libpam pop

will produce the following output:

     WITH_READLINE
     USE_LIBPAM
     ENABLE_POP

and will exit with a zero status.

The following command:

     $ mailutils --info readline gssapi pop

will exit with status 1, and will print:

     WITH_READLINE
     ENABLE_POP

since WITH_GSSAPI flag is not defined.

The flags and their meanings are:
