#  Curses needs the following two variables defined here in order to
#  compile the library.  They are:
#
#    $inc    contains any includes or defines (-I or -D) that are
#               needed to compile libcurses applications
#    $libs   contains any libraries or library paths (-l or -L) that are
#               needed to compile libcurses applications

my $inc;
my $libs;

# If you do not set these explicitly, Makefile.PL will try in a fairly
# stupid fashion to pick them for you, along with a "c-config.h" file.
#
# If you want to see examples of what needs to go in the $inc and
# $libs variables, check out the `guess_cfg' tables of values below.
# In fact, one way to set the variables would be to add or modify an
# entry for your 'osname'.  If you're not sure what the osname is for
# your machine, you can use the following at your command line to
# print it out:
#
#    perl -e 'use Config; print "$Config{osname}\n"'
#
# Some lines have multiple versions (such as `freebsd' and `linux'),
# representing different versions of curses that an OS might have.
# You can pick the version you want by setting the `default' entry.

# Here are some notes provided by the hint providers for certain of the
# OSes.  You should scan them first to see if they apply to you.

# Notes for FreeBSD ncurses:
#   [Courtesy of "Andrew V. Stesin" <stesin@elvisti.kiev.ua>]
#   FreeBSD-2.0.5 ncurses + mytinfo	NOTE! Straight curses works much
#					better for me!
#
# Notes for Solaris:
#   Under 2.3, it was reported that to get the module to compile properly
#   with gcc, you must add `-DSYSV=1' to $inc.  This will disable the
#   redefinition of memcpy to bcopy that is present in /usr/include/curses.h.
#   [Courtesy of Dave Blaszyk <dvb@ycc.Kodak.COM>]
#
#   $inc also contained "-I/usr/include", but this seems to cause a great
#   deal of trouble for gcc under perl5.002, so I removed it by default.
#   I have tested Curses-a9 with perl5.002 and gcc263 and Sun's unbundled
#   cc on Solaris 2.4 with an empty $inc and had no problems, but your
#   mileage may vary.
#
#   If you are having trouble compiling under Solaris, try various
#   combinations of "-I/usr/include" and "-DSYSV=1" in $inc to see if
#   it fixes things.

I'm sorry, but I could not make a good guess for the includes and

follow the instructions for defining the $inc and $libs variables.

I'm sorry, but I couldn't find a hints file that was configured for
your OS.  You will need to create and configure a "c-config.h" file
for yourself.  Please see the "INSTALL" directions for pointers on how
to do this.

I'm sorry.  I was going to try and pick a "c-config.h" for you, but it
looks like there are some non-standard characters in the exec string.
I'm feeling rather paranoid, so I'll let you look at the line and do
it by hand if it looks OK.  I wanted to execute a symbolic link or
copy as follows:

   ln -s $source.h c-config.h [or]
   cp    $source.h c-config.h

Config said I might be able to use:

   $sys

but it has the (possibly) naughty character '$1' in it.
