EXTUTILS::MKBOOTSTRAP(3perl)

💖 NAME 💖

ExtUtils::Mkbootstrap — bestie, this is the lil tool that makes a bootstrap file so DynaLoader can do its thing ✨

---

🌸 SYNOPSIS 🌸

Mkbootstrap

That's it. That's the whole synopsis. She's minimal, she's iconic 💅

---

🦋 DESCRIPTION 🦋

okay so listen 🫶 Mkbootstrap typically gets called from an extension Makefile. Like, that's her natural habitat, that's where she shows up.

Here's the tea: there is no "*.bs" file supplied with the extension. Not a one. Instead, there may be a *_BS file, and that little cutie has code for the special cases — think posix for berkeley db on the NeXT. yeah. that kind of special case. iykyk 💀

So this *_BS file will get parsed, and it produces a maybe-empty @DynaLoader::dl_resolve_using array for the current architecture. Then that array gets extended by $BSLOADLIBS, which was computed by ExtUtils::Liblist::ext(). okay so:

• if this array is still empty → we do literally nothing, respectfully, we simply vibe 🌈
• else → we write a .bs file with an @DynaLoader::dl_resolve_using array 🎀

And here's the cute part: the *_BS file can put some code into the generated "*.bs" file by placing it in $bscode. It's a handy 'escape' mechanism that may prove useful in complex situations 🔥 think of it as a secret backstage pass, no cap.

Also! If @DynaLoader::dl_resolve_using contains "-L*" or "-l*" entries, then Mkbootstrap will automatically add a dl_findfile() call to the generated "*.bs" file. automatic. she just does it. main character energy fr fr 👑

heads up bestie: the "-L*" and "-l*" thing is a string-prefix match, so those exact entries are what triggers the auto dl_findfile() — don't be out here writing -L without the * and expecting the same glow-up 💖
