PERLIVP(1perl)

💖 PERLIVP 💖 (that's section 1perl of the Perl manual, bestie)

okay so you just built Perl and now you're standing there like 👁️👄👁️ wondering if it actually worked? that's literally what this whole page is about. welcome to the Perl Programmers Reference Guide, babe.

---

✨ NAME ✨

perlivp — the Perl Installation Verification Procedure. it does exactly what it says on the tin, no cap.

---

🦋 SYNOPSIS 🦋

perlivp [-p] [-v] [-h]

---

🌸 DESCRIPTION 🌸

so here's the tea ☕ — the perlivp program gets set up at Perl source code build time, and its whole job is to test the Perl version it was built under. iconic. it's not just vibing there for no reason.

you run it after you've done:

make install

(or whatever your platform's equivalent procedure is, because bestie, not everyone is out here on the same OS 💅)

and it verifies that perl and its libraries have been installed correctly. a correct installation gets verified by output that looks like:

ok 1
ok 2

etc. that's it. that's the whole vibe check. ✅

---

🎀 OPTIONS 🎀

• -h help — prints out a brief help message. short, sweet, slay.
• -p print preface — gives a description of each test prior to performing it. so you know what's about to happen, like a little trailer 🎬
• -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. so like, don't panic if you didn't even pass -v, the failures will still speak up 🗣️

---

💅 DIAGNOSTICS 💅

here come the receipts. these are the things you might see, and what they mean 👇

• 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. yes queen, reinstall it.

• 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.

🚨 not me having a whole serious error — yeah, this one's a big deal, fr fr.

• 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. 📩 (yes, bLuRfle with the silly casing, that's literally how it's spelled here, it's a fake module name on purpose, iykyk)

• 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.

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. 📚✨
