\`configure' configures Wireshark 2.2.3 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:
--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]

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: <http://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.

# Using Import Files as archive members, it is possible to support
# filename-based versioning of shared library archives on AIX. While
# this would work for both with and without runtime linking, it will
# prevent static linking of such archives. So we do filename-based
# shared library versioning with .so extension only, which is used
# when both runtime linking and shared linking is enabled.
# Unfortunately, runtime linking may impact performance, so we do
# not want this to be the default eventually. Also, we use the
# versioned .so libs for executables only if there is the -brtl
# linker flag in LDFLAGS as well, or --with-aix-soname=svr4 only.
# To allow for filename-based versioning support, we need to create
# libNAME.so.V as an archive file, containing:
# *) an Import File, referring to the versioned filename of the
# archive as well as the shared archive member, telling the
# bitwidth (32 or 64) of that shared object, and providing the
# list of exported symbols of that shared object, eventually
# decorated with the 'weak' keyword
# *) the shared object with the F_LOADONLY flag set, to really avoid
# it being seen by the linker.
# At run time we better use the real file rather than another symlink,
# but for link time we create the symlink libNAME.so -> libNAME.so.V

# Using Import Files as archive members, it is possible to support
# filename-based versioning of shared library archives on AIX. While
# this would work for both with and without runtime linking, it will
# prevent static linking of such archives. So we do filename-based
# shared library versioning with .so extension only, which is used
# when both runtime linking and shared linking is enabled.
# Unfortunately, runtime linking may impact performance, so we do
# not want this to be the default eventually. Also, we use the
# versioned .so libs for executables only if there is the -brtl
# linker flag in LDFLAGS as well, or --with-aix-soname=svr4 only.
# To allow for filename-based versioning support, we need to create
# libNAME.so.V as an archive file, containing:
# *) an Import File, referring to the versioned filename of the
# archive as well as the shared archive member, telling the
# bitwidth (32 or 64) of that shared object, and providing the
# list of exported symbols of that shared object, eventually
# decorated with the 'weak' keyword
# *) the shared object with the F_LOADONLY flag set, to really avoid
# it being seen by the linker.
# At run time we better use the real file rather than another symlink,
# but for link time we create the symlink libNAME.so -> libNAME.so.V
