388 perlivp - Perl Installation Verification Procedure
392 B<perlivp> [B<-a>] [B<-p>] [B<-v>] [B<-h>]
396 The B<perlivp> program is set up at Perl source code build time to test the
397 Perl version it was built under. It can be used after running:
401 (or your platform's equivalent procedure) to verify that B<perl> and its
402 libraries have been installed correctly. A correct installation is verified
403 by output that looks like:
416 Prints out a brief help message.
418 =item B<-a> run all tests
420 Normally tests for optional features are skipped. With -a all tests
423 =item B<-p> print preface
425 Gives a description of each test prior to performing it.
429 Gives more detailed information about each test, after it has been performed.
430 Note that any failed tests ought to print out some extra information whether
439 =item * print "# Perl binary `$perlpath' does not appear executable.\n";
441 Likely to occur for a perl binary that was not properly installed.
442 Correct by conducting a proper installation.
444 =item * print "# Perl version `$]' installed, expected $ivp_VERSION.\n";
446 Likely to occur for a perl that was not properly installed.
447 Correct by conducting a proper installation.
449 =item * print "# Perl \@INC directory `$_' does not appear to exist.\n";
451 Likely to occur for a perl library tree that was not properly installed.
452 Correct by conducting a proper installation.
454 =item * print "# Needed module `$_' does not appear to be properly installed.\n";
456 One of the two modules that is used by perlivp was not present in the
457 installation. This is a serious error since it adversely affects perlivp's
458 ability to function. You may be able to correct this by performing a
459 proper perl installation.
461 =item * print "# Required module `$_' does not appear to be properly installed.\n";
463 An attempt to C<eval "require $module"> failed, even though the list of
464 extensions indicated that it should succeed. Correct by conducting a proper
467 =item * print "# Unnecessary module `bLuRfle' appears to be installed.\n";
469 This test not coming out ok could indicate that you have in fact installed
470 a bLuRfle.pm module or that the C<eval " require \"$module_name.pm\"; ">
471 test may give misleading results with your installation of perl. If yours
472 is the latter case then please let the author know.
474 =item * print "# file",+($#missing == 0) ? '' : 's'," missing from installation:\n";
476 One or more files turned up missing according to a run of
477 C<ExtUtils::Installed -E<gt> validate()> over your installation.
478 Correct by conducting a proper installation.
480 =item * print "# Perl header `$_' does not appear to be properly installed.\n";
482 Correct by running B<h2ph> over your system's C header files. If necessary,
483 edit the resulting *.ph files to eliminate perl syntax errors.
487 For further information on how to conduct a proper installation consult the
488 INSTALL file that comes with the perl source and the README file for your
