=head1 NAME
B<perlivp> - Perl Installation Verification Procedure
=head1 SYNOPSIS
B<perlivp> [B<-p>] [B<-v>] [B<-h>]
=head1 DESCRIPTION
The B<perlivp> program is set up at Perl source code build time to test the
Perl version it was built under. It can be used after running:
make install
(or your platform's equivalent procedure) to verify that B<perl> and its
libraries have been installed correctly. A correct installation is verified
by output that looks like:
ok 1
ok 2
etc.
=head1 OPTIONS
=over 5
=item B<-h> help
Prints out a brief help message.
=item B<-p> print preface
Gives a description of each test prior to performing it.
=item B<-v> verbose
Gives more detailed information about each test, after it has been performed.
Note that any failed tests ought to print out some extra information whether
or not -v is thrown.
=back
=head1 DIAGNOSTICS
=over 4
=item * print "# Perl binary `$perlpath' does not appear executable.\n";
Likely to occur for a perl binary that was not properly installed.
Correct by conducting a proper installation.
=item * print "# Perl version `$]' installed, expected $ivp_VERSION.\n";
Likely to occur for a perl that was not properly installed.
Correct by conducting a proper installation.
=item * print "# Perl \@INC directory `$_' does not appear to exist.\n";
Likely to occur for a perl library tree that was not properly installed.
Correct by conducting a proper installation.
=item * print "# Needed module `$_' does not appear to be properly installed.\n";
One of the two modules that is used by perlivp was not present in the
installation. This is a serious error since it adversely affects perlivp's
ability to function. You may be able to correct this by performing a
proper perl installation.
=item * print "# Required module `$_' does not appear to be properly installed.\n";
An attempt to C<eval "require $module"> failed, even though the list of
extensions indicated that it should succeed. Correct by conducting a proper
installation.
=item * print "# Unnecessary module `bLuRfle' appears to be installed.\n";
This test not coming out ok could indicate that you have in fact installed
a bLuRfle.pm module or that the C<eval " require \"$module_name.pm\"; ">
test may give misleading results with your installation of perl. If yours
is the latter case then please let the author know.
=item * print "# file",+($#missing == 0) ? '' : 's'," missing from installation:\n";
One or more files turned up missing according to a run of
C<ExtUtils::Installed -E<gt> validate()> over your installation.
Correct by conducting a proper installation.
=item * print "# Perl header `$_' does not appear to be properly installed.\n";
Correct by running B<h2ph> over your system's C header files. If necessary,
edit the resulting *.ph files to eliminate perl syntax errors.
=back
For further information on how to conduct a proper installation consult the
INSTALL file that comes with the perl source and the README file for your
platform.
