This makes +single host installs simple, and simplifies changing the default +location for the install tree, but doesn't allow for multiple hosts to +effectively share host independent files. + +To configure so that multiple hosts can share common files, use +something like: + +@example +configure @var{host1} -prefix=/usr/gnu/H-@var{host1} -datadir=/usr/gnu/H-independent +make all info install install-info clean +configure @var{host2} -prefix=/usr/gnu/H-@var{host2} -datadir=/usr/gnu/H-independent +make all info install install-info +@end example + +The first line configures the source for @var{host1} in such a way that +host specific programs will be placed in subdirectories of +@file{/usr/gnu/H-@var{host1}} and host independent files will be placed +in @file{/usr/gnu/H-independent}. (See @xref{datadir}.) + +The second line builds and installs all programs for @var{host1}, +including both host independent and host dependent files. + +The third line reconfigures the source for @var{host2} in such a way +that host specific programs will be placed in subdirectories of +@file{/usr/gnu/H-@var{host2}} and host independent files will again be +placed in @file{/usr/gnu/H-independent}. + +The fourth line builds and installs all programs for @var{host2}. Host +dependent files will be installed in new directories but the host +independent files will be installed @emph{on top of} the host +independent files installed for @var{host1}.

This is usually used to +distinguish betwen the numerous variations between @emph{common} +operating systems. +@end defvar + +@defvar{host_os} +Contains the the third element of the canonical triple representing the +host as returned by @file{config.subr}. +@end defvar + +@defvar{target} +Contains the actual name that the user entered for the target. Since many +things that the user could enter would map to the same canonical triple, +this variable is innappropriate to use for picking available +configurations. For that, use @code{target_cpu}, @code{target_vendor}, +and/or @code{target_os}. This variable is useful, however, for error +messages. +@end defvar + +@defvar{target_cpu} +Contains the first element of the canonical triple representing the +target as returned by @file{config.subr}. This is used heavily by +programs involved in building programs, like the compiler, assembler, +linker, etc. Most programs will not need the @code{target} variables at +all, but this one could conceivably be used to build a program, for +instance, that operated on binary data files whose byte order or +alignment are other than that of the system on which the program is +running. +@end defvar + +@defvar{target_vendor} +Contains the second element of the canonical triple representing the +target as returned by @file{config.subr}. This is usually used to +distinguish betwen the numerous variations between @emph{common} +operating systems or object file formats. Sometimes it is used to +switch between different flavors of users interfaces. +@end defvar + +@defvar{target_os} +Contains the the third element of the canonical triple representing the +target as returned by @file{config.subr}. This variable is used by +development tools to distinguish between subtle variations in object +file formats that some vendors use across operating system releases. It +might also be use to decide which libraries to build or what user +interface the tool should provide. +@end defvar + +@defvar{nfp} +Is set to @code{true} if the user invoked configure with the @code{-nfp} +command line option, otherwise it is empty. This is a request to target +a machine with @emph{no floating point} unit, even if the machine ordinarily +has a floating point unit available. This option has no negation. +@end defvar + +@defvar{gas} +Is set to @code{true} if the user invoked configure with the @code{-gas} +command line option, otherwise it is empty. This is a request to assume +that the target machine has gas available even if it ordinarily does +not. The converse option, @code{-no-gas} is not available. +@end defvar + +@defvar{x} +Is set to @code{true} if the user invoked configure with the @code{-x} +command line option, otherwise it is empty. This is a request to assume +that @sc{mit x11} compatible headers files and libraries are available, +regardless of what is normally available on this host. +@end defvar + +@defvar{srcdir} +Is set to the name of the directory containing the source for this +program. This will be different from @file{.} if the user has +specified either the @code{-srcdir=} or the @code{-subdirs} options. +Note that @code{srcdir} is not necessarily an absolute path. +@end defvar + +@defvar{host_makefile_frag} +Is set to a file name representing to the default Makefile fragment for +this host. It may be set in @file{configure.in} to overide this +default. +@end defvar + +@defvar{target_makefile_frag} +Is set to a file name representing to the default Makefile fragment for +this target. It may be set in @file{configure.in} to overide this +default. +@end defvar + +@defvar{site_makefile_frag} +Is set to a file name representing to the default Makefile fragment for +this host. It may be set in @file{configure.in} to overide this +default. Normally @code{site_makefile_frag} is empty, but will have a +value if the user specified @code{-site=} on the command line. This +variable should probably not be overridden. +@end defvar + +@defvar{Makefile} +Is set to the name of the generated @file{Makefile}. Normally this +value is precisely @file{Makefile} but some programs may want something +else. +@end defvar + +@defvar{removing} +Is normally empty but will be set to some non-empty value if the user +specified @code{-rm} on the command line. That is, if @code{removing} +is non-empty, then configure is @emph{removing} a configuration rather +than creating one. +@end defvar + +@defvar{files} +If this variable is non-empty following the @code{per-target:} section, +then each word in it's value will be the target of a symbolic link +named in the @code{links} variable. +@end defvar + +@defvar{links} +If the @code{files} variable is non-empty following the +@code{per-target:} section, then symbolic links will be created with the +first word of links pointing to the first word of files, the second word of +links pointing to the second word of files, and so on. +@end defvar + +@end itemize +@end itemize + +@node Automagic Configuration, , Makefile Support, Adding Configure To Existing Programs +@section Automagic Configuration + + +@menu +* Should Be Used If Prep'D Files Don'T Exist:: Should Be Used If Prep'D Files Don'T Exist +@end menu + +@node Should Be Used If Prep'D Files Don'T Exist, , Automagic Configuration, Automagic Configuration +@subsection Should Be Used If Prep'D Files Don'T Exist + + + +@node Known Bugs, Variables Index, Adding Configure To Existing Programs, top +@chapter Known Bugs + +The following bugs are known to exist. + +@itemize @bullet + +@item +There is no way to query about known hosts, known targets, or the +porting or testing status of any configuration. + +@item +The negations to the options @code{-gas}, @code{-x}, and @code{-nfp} are +not available. + +@end itemize + +@node Variables Index, Concept Index, Known Bugs, top +@unnumbered Variable Index + +@printindex vr + +@node Concept Index, , Variables Index, top +@unnumbered Concept Index + +@printindex cp + +@summarycontents +@contents +@bye + +@c Local Variables: +@c fill-column: 79 +@c outline-regexp: "@chap" +@c End: +@c (setq outline-regexp "@chapt\\\|@unnum\\\|@setf\\\|@conte\\\|@sectio\\\|@subsect\\\|@itemize\\\|@defvar{") |
