Perl 5 version 12.3 documentation
perlivp - Perl Installation Verification Procedure
perlivp [-a] [-p] [-v] [-h]
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
- -h help
Prints out a brief help message.
- -a run all tests
Normally tests for optional features are skipped. With -a all tests are executed.
- -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.
- 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",+($#missing == 0) ? '' : 's'," missing from installation:\n";
One or more files turned up missing according to a run of
ExtUtils::Installed -> validate()over your installation. Correct by conducting a proper installation.
- print "# Perl header `$_' does not appear to be properly installed.\n";
Correct by running h2ph over your system's C header files. If necessary, edit the resulting *.ph files to eliminate perl syntax errors.
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.
