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