.Sh NAME
.Nm autoswc
.Nd generates system wide cache files for GNU autoconf
.Sh SYNOPSIS
.Nm
.Op Fl c Ar ac_file
.Op Fl n Ar cache_name
.Sh DESCRIPTION
.Nm
is an utility that automatically generates system wide cache files for use
with configure scripts created by
.Nm GNU autoconf ,
and specially by those executed within
.Nm pkgsrc .
.Pp
.Nm
starts by reading the configuration script template.
It will use
.Pa @SYSCONFDIR@/configure.ac
if found, or fallback to
.Pa @PREFIX@/share/autoswc/configure.ac
otherwise (a custom file may be given using the
.Fl c
flag, though).
This issues all checks that the user wants to store in the system wide
cache file, and are basically calls to standard
.Nm GNU autoconf ,
.Nm GNU automake
and/or
.Nm GNU libtool
macros.
There is no need to manually execute any of the
.Sq AC_INIT ,
.Sq AM_INIT_AUTOMAKE ,
.Sq AC_CACHE_SAVE
and
.Sq AC_OUTPUT
macros, as they are automatically inserted in the right place during
execution.
.Pp
The default cache file is stored inside the
.Pa @CACHEDIR@
directory, using
.Pa config.cache.default
as the file name.
The
.Sq default
part can be changed using the
.Fl n
flag, which takes the base name of the cache file.
.Pp
To tell
.Nm pkgsrc
to use the system wide cache, all you need to do is append the following
line to your
.Pa @MKCONF@
file:
.Bd -literal -offset indent
\&.sinclude "@PREFIX@/share/autoswc/autoswc.mk"
.Ed
.Pp
In case you used the
.Fl n
flag, you also need to define the
.Va AUTOSWC_CACHE_NAME
variable in this file, setting it to the value passed to the flag.
.Sh NOTES
Be very careful about what you add to
.Pa configure.ac .
You should only check for things that are unlikely to change over time,
as functions in the
.Lb libc
and its header files.
Failure to do so can easily lead to cache files that get outdated very
easily during installation of new packages, and cause unexpected
configuration errors.
.Pp
It is recommended that you rebuild the cache file periodically.
You can configure a simple
.Xr cron 8
job to it, which just needs to launch this utility.
.Pp
If you hit a compilation problem in any package when using
.Nm ,
be
.Em absolutely
sure it is not beeing caused by an outdated cache before reporting
problems.
The safest and easiest way to do this is to clean the package in question
and restart the build with the
.Va AUTOSWC_DISABLE
variable set, like in the following example:
.Bd -literal -offset indent
$ @MAKE@ clean
$ @MAKE@ AUTOSWC_DISABLE=YES
.Ed

You have used a non-standard cache name. To let configure scripts

Please remember that by using a system wide cache file, you assume
that the results stored in it may get outdated and cause strange build

sure it is not your fault. Check the autoswc(8) manpage for more
details.
