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