[PATCH VTPM v9 6/8] stubdom: Add autoconf

Matthew Fioravante
Thu, 10 Jan 2013 23:01:05 -0000

Stub domains now use autoconf to build.
This configure script can enable or disable specific domains
and also specify custom download locations for stubdom library
packages. See ./configure --help for details.

C and Caml are disabled by default. vtpm-stubdom is conditional
on the presense of cmake.

Rename vtpmmgrdom to vtpmmgr-stubdom

Also update .*ignore

+\`configure'' configures Xen Hypervisor Stub Domains 4.3 to adapt to
many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...'' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache''
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or
\`..'']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install'' will install all the files in
+\`$ac_default_prefix/bin'', \`$ac_default_prefix/lib'' etc.
You can specify
+an installation prefix other than \`$ac_default_prefix'' using
\`--prefix'',
+for instance \`--prefix=\$HOME''.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
