perlivp \- Perl Installation Verification Procedure
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBperlivp\fR [\fB\-a\fR] [\fB\-p\fR] [\fB\-v\fR] [\fB\-h\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBperlivp\fR 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:
.PP
.Vb 1
\&    make install
.Ve
.PP
(or your platform's equivalent procedure) to verify that \fBperl\fR and its
libraries have been installed correctly.  A correct installation is verified
by output that looks like:
.PP
.Vb 2
\&    ok 1
\&    ok 2
.Ve
.PP
etc.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-h\fR help" 5
.IX Item "-h help"
Prints out a brief help message.
.IP "\fB\-a\fR run all tests" 5
.IX Item "-a run all tests"
Normally tests for optional features are skipped.  With \-a all tests
are executed.
.IP "\fB\-p\fR print preface" 5
.IX Item "-p print preface"
Gives a description of each test prior to performing it.
.IP "\fB\-v\fR verbose" 5
.IX Item "-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.
.SH "DIAGNOSTICS"
.IX Header "DIAGNOSTICS"
.IP "\(bu" 4
print \*(L"# Perl binary `$perlpath' does not appear executable.\en\*(R";
.Sp
Likely to occur for a perl binary that was not properly installed.
Correct by conducting a proper installation.
.IP "\(bu" 4
print \*(L"# Perl version `$]' installed, expected \f(CW$ivp_VERSION\fR.\en\*(R";
.Sp
Likely to occur for a perl that was not properly installed.
Correct by conducting a proper installation.
.IP "\(bu" 4
print \*(L"# Perl \e@INC directory `$_' does not appear to exist.\en\*(R";
.Sp
Likely to occur for a perl library tree that was not properly installed.
Correct by conducting a proper installation.
.IP "\(bu" 4
print \*(L"# Needed module `$_' does not appear to be properly installed.\en\*(R";
.Sp
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.
.IP "\(bu" 4
print \*(L"# Required module `$_' does not appear to be properly installed.\en\*(R";
.Sp
An attempt to \f(CW\*(C`eval "require $module"\*(C'\fR failed, even though the list of 
extensions indicated that it should succeed.  Correct by conducting a proper 
installation.
.IP "\(bu" 4
print \*(L"# Unnecessary module `bLuRfle' appears to be installed.\en\*(R";
.Sp
This test not coming out ok could indicate that you have in fact installed 
a bLuRfle.pm module or that the \f(CW\*(C`eval " require \e"$module_name.pm\e"; "\*(C'\fR
test may give misleading results with your installation of perl.  If yours
is the latter case then please let the author know.
.IP "\(bu" 4
print \*(L"# file\*(R",+($#missing == 0) ? '' : 's',\*(L" missing from installation:\en\*(R";
.Sp
One or more files turned up missing according to a run of 
\&\f(CW\*(C`ExtUtils::Installed \-> validate()\*(C'\fR over your installation.
Correct by conducting a proper installation.
.IP "\(bu" 4
print \*(L"# Perl header `$_' does not appear to be properly installed.\en\*(R";
.Sp
Correct by running \fBh2ph\fR over your system's C header files.  If necessary, 
edit the resulting *.ph files to eliminate perl syntax errors.
.PP
For further information on how to conduct a proper installation consult the 
\&\s-1INSTALL\s0 file that comes with the perl source and the \s-1README\s0 file for your 
platform.
