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