NAME
perlivp - Perl Installation Verification Procedure
SYNOPSIS
perlivp [-p] [-v] [-h]
DESCRIPTION
The 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 perl and its
libraries have been installed correctly. A correct installation is
verified by output that looks like:
ok 1
ok 2
etc.
OPTIONS
-h help
Prints out a brief help message.
-p print preface
Gives a description of each test prior to performing it.
-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.
DIAGNOSTICS
• print "# Perl binary '$perlpath' does not appear executable.\n";
Likely to occur for a perl binary that was not properly installed.
Correct by conducting a proper installation.
• print "# Perl version '$]' installed, expected $ivp_VERSION.\n";
Likely to occur for a perl that was not properly installed.
Correct by conducting a proper installation.
• print "# Perl \@INC directory '$_' 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.
• print "# Needed module '$_' does not appear to be properly
installed.\n";
One of the two modules that is used by perlivp was not present in
the installation. This is a serious error since it adversely
affects perlivp's ability to function. You may be able to correct
this by performing a proper perl installation.
• print "# Required module '$_' does not appear to be properly
installed.\n";
An attempt to "eval "require $module"" failed, even though the list
of extensions indicated that it should succeed. Correct by
conducting a proper installation.
• print "# Unnecessary module 'bLuRfle' appears to be installed.\n";
This test not coming out ok could indicate that you have in fact
installed a bLuRfle.pm module or that the "eval " require
\"$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.
• print "# file",+($#missing == 0) ? '' : 's'," missing from
installation:\n";
One or more files turned up missing according to a run of
"ExtUtils::Installed -> validate()" over your installation.
Correct by conducting a proper installation.
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.
