Perl Installation Verification Procedure

## 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.
