 \`configure' configures bcm2835 1.71 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:
   --bindir=DIR            user executables [EPREFIX/bin]
   --sbindir=DIR           system admin executables [EPREFIX/sbin]
   --libexecdir=DIR        program executables [EPREFIX/libexec]
   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
   --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
   --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
   --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
   --libdir=DIR            object code libraries [EPREFIX/lib]
   --includedir=DIR        C header files [PREFIX/include]
   --oldincludedir=DIR     C header files for non-gcc [/usr/include]
   --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
   --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
   --infodir=DIR           info documentation [DATAROOTDIR/info]
   --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
   --mandir=DIR            man documentation [DATAROOTDIR/man]
   --docdir=DIR            documentation root [DATAROOTDIR/doc/bcm2835]
   --htmldir=DIR           html documentation [DOCDIR]
   --dvidir=DIR            dvi documentation [DOCDIR]
   --pdfdir=DIR            pdf documentation [DOCDIR]
   --psdir=DIR             ps documentation [DOCDIR]

 Program names:
   --program-prefix=PREFIX            prepend PREFIX to installed program names
   --program-suffix=SUFFIX            append SUFFIX to installed program names
   --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

 Optional Features:
   --disable-option-checking  ignore unrecognized --enable/--with options
   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
   --enable-silent-rules   less verbose build output (undo: "make V=1")
   --disable-silent-rules  verbose build output (undo: "make V=0")
   --enable-dependency-tracking
                           do not reject slow dependency extractors
   --disable-dependency-tracking
                           speeds up one-time build
 Some influential environment variables:
   CC          C compiler command
   CFLAGS      C compiler flags
   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
               nonstandard directory <lib dir>
   LIBS        libraries to pass to the linker, e.g. -l<library>
   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
               you have headers in a nonstandard directory <include dir>
 Use these variables to override the choices made by `configure' or to help
 it to find libraries and programs with nonstandard names/locations.

 Oops!
 Your 'rm' program seems unable to run without file operands specified
 on the command line, even when the '-f' option is present.  This is contrary
 to the behaviour of most rm programs out there, and not conforming with
 the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
 Please tell bug-automake@gnu.org about your system, including the value
 of your $PATH and any error possibly output before this message.  This
 can help us improve future automake versions.

 Aborting the configuration process, to ensure you take notice of the issue.
 You can download and install GNU coreutils to get an 'rm' implementation
 that behaves properly: <https://www.gnu.org/software/coreutils/>.
 If you want to complete the configuration process using your problematic
 'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
 to "yes", and re-run configure.
