perlivp - Perl Installation Verification Procedure
program is set up at Perl source code build time to test thePerl version it was built under. It can be used after running:
(or your platform's equivalent procedure) to verify that perl and itslibraries have been installed correctly. A correct installation is verifiedby output that looks like:
ok 1 ok 2
- -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 whetheror not -v is thrown.
- 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 '$_' does not appear to be properly installed.\n'';
One of the two modules that is used by perlivp was not present in the installation. This is a serious error since it adversely affects perlivp'sability to function. You may be able to correct this by performing aproper perl installation.
- print ``# Required module '$_' 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 yoursis 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.
